How to change your Nameservers

A name server forms the backbone of the DNS (Domain Name System) and is an important part of creating a link from a domain name to a website and/or email service. Sometimes you may need to point your domain name to alternative nameservers. You can update the nameservers for you domain in you account control panel. Log in to your account. Click the Domains icon and choose the Manage next to the domain you wish to amend. Click Nameservers in the Current Domain menu on the top left. In the Primary field under Hostname enter the first nameserver address (nameserver addresses typically start with ns0. or ns1.). In the Secondary field under Hostname enter your second nameserver address. The IP Address field is optional, you can leave this blank. Click Update and allow up to 48 hours for the changes to take effect. NoteYour nameserver changes will normally complete within a few hours, however it can take up to 48 hours for your changes to update globally. WarningIf you are using any of our Web Hosting or Email forwarding services, we do not recommend changing your nameservers as these services will no longer function. Here is a quick demonstration

How to create an A record

A records are the part of the Domain name system (DNS) which maps a domain name to an IP address. This is most commonly used to point a domain name to an server IP address. Another popular DNS use is to help identify services or resources by their hostname, for example: mail.domain.com, ftp.domain.com, shop.domain.com. Both of these can be easily achieved with an Address (A) Record. Log in to your LCN.com account. Click the Domains icon and choose the domain you wish to manage. Click DNS Settings in the Current Domain menu on the left. Click the Add An A Record button. In the Hostname field enter the the text you want before your domain e.g. www In the IP Address field enter the IP address of your server e.g. 94.126.40.226. Click Add A Record and allow up to 24hrs for the changes to take effect. Note: Leaving the hostname field blank will create a blank A record. This means that if anybody types in your wbsite name with www, it will still resolve IF set up on the server side. Our shared hosting offers this as a standard feature. New A records will normally start resolving your hostname to the IP address straight away, although you may need to do some more configuration on the server it is pointing to before it is useful e.g. add it to an Apache web server configuration. Here is a quick demonstration

How to create a CNAME record

When you setup a website, it's quite common to buy all of the most popular extensions (e.g. .com, .co.uk) to make sure as many people as possible can easily get to your website. Normally you will only have one website but want both domains to point to it. Adding a CNAME allows you to get both the .com and .co.uk version of your domain loading your website. CNAME or Canonical name records are used to map or point one hostname to another, for example to alias www.domain.com to www.domain.co.uk. Here's how to create a CNAME record for your domain name: Log in to your LCN.com account. Click the Domains icon and select Manage next to the domain you wish to amend. Click Edit DNS Settings in the Current Domain menu on the left. Scroll down to the CNAME section and click the Add A CNAME Record button. In the Alias field enter the text you want before your domain. For example: Entering www will create the full hostname that be aliased (www.yourdomain.com). Note: The alias field can't be blank. In the Hostname field enter the address of the domain you want to point to e.g. www.domain.co.uk. Click Add CNAME Record and allow up to 24hrs for the changes to take effect. New CNAME records will normally start aliasing to the alternative hostname straight away, however if you were running a website for www.domain.co.uk you would also need to configure the web servers virtual host and include a ServerAlias directive listing the domain you've just aliased. Here is a quick demonstration

How to create an MX record

MX records are the part of the Domain name system (DNS) which serve your email. These normally come in pairs and direct any mail requests on your domain name to the mail server associated with these records. Normally your website and email would be served by the same server or system. However there are situations where you may need to separate them, for example if you want to run your own office mail server or if you want to use a third party mail scanning service. Here's how to create a MX record for your domain name: Log in to your LCN.com account. Click the Domains icon and choose the domain you wish to manage. Click DNS Settings in the Current Domain menu on the left. Click the Add A MX Record button. In the Mail Server field enter the address of the server that will handle your email e.g. mx1.lcn.com. In the Priority field enter the weighting for the mail server, the lowest number will be tried first for delivery, normally a domain will have at least two MX records acting as primary and secondary delivery destinations. Click Add MX Record and allow up to 24hrs for the changes to take effect. New MX records will normally be available for delivering mail straight away (depending on their priority), although you may need to do some more configuration on the mail server you are pointing to before mail is accepted. As with any DNS change, we do advise waiting up to 24 hours for propagation of this change. Here is a quick demonstration

How to create an SPF record

Sender Policy Framework (SPF) records specify which mail servers can send email on behalf of your domain. SPF was created to prevent spammers from sending forged email messages with a From address at your domain name. When an email message is received, the mail server uses the SPF record to check that mail from your domain is being sent by an authorised mail server, if not the mail server can reject it as spam. A common request for SPF records comes from customers using Google Apps with their domain. Google will supply the SPF value for you. If you would like to create your own have a look at this SPF syntax guide. You use a TXT record to create your SPF DNS entry. Here's how to create a SPF record for your domain name: Log in to your LCN.com account. Click the Domains icon and choose Manage next to the domain you wish to amend. Click DNS Settings in the Current Domain menu on the left. Click the Add A TXT Record button. Leave the Name field blank. In the Data field enter your SPF value e.g. v=spf1 include:_spf.google.com ~all. Click Add TXT Record and allow up to 24hrs for the changes to take effect. If you are using our shared hosting platform, the default SPF record we use is as follows: v=spf1 ip4:94.126.40.0/24 ip4:94.126.44.32/27 ?all Warning Please be cautious when configuring your SPF record as doing so incorrectly may result in email not being accepted from your domain. If you would like to check that an SPF record has been configured correctly - you can contact the LCN support team.

How to create a DKIM record

Domain Keys Identified Mail (DKIM) records allow you to digitally sign emails from your domain. Recipients of your emails can then verify that the message really did come from your domain and has not been tampered with. DKIM, like SPF records, are another tool to help fight spam. SPF allows recipients to verify an email message came from an authorised mail server, DKIM allows recipients to verify the actual message. DKIM works by using public and private encryption keys. The private key is used to create encrypted mail headers that are embedded in every email message you send and are unique to your domain. The public key is added to the DNS records for your domain which allows recipients to retrieve it and then use it to decrypt the header and verify the message. A common request for DKIM records comes from customers using Google Apps with their domain. Google will supply the DKIM selector name and value for you. If you run your own mail server and would like to start signing your own emails, dkim.org is a good place to start. Here's how to create a DKIM DNS record for your domain name: Log in to your LCN.com account. Click the Domains icon and click Manage on the domain you wish to amend. Click DNS Settings in the Current Domain menu on the left. Click the Add A TXT Record button. In the Name field enter a string that will distingush this key from any others, also known as a selector prefix, e.g. google._domainkey. In the Data field enter your public encryption key, e.g v=DKIM1; k=rsa; p=p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDeIhtCv3vUinyhKiKtZ8efjHGGo 8gE1T+o7gLrvo6yRtdz9ICe6Fz5sgz0WYFW5nCV4DmaTcS25TfgWKsLggGSBdDxzShyvg dKJkG3b4+73rT/5opnRceqQf1qndnMZfkb/0/YciMKNQmigj9IGwKypj6CoIr1s46jRG y4Ws7LQIDAQAB Click Add TXT Record and allow up to 24hrs for the changes to take effect. WarningPlease take care when configuring your DKIM record as doing this incorrectly may result in your email from your domain being flagged as spam. Here is a quick demonstration

How to reset your Nameservers

A name server forms the backbone of the DNS. Its main job is to translate the domain name into its corresponding IP address which in turn links to your website and email services Our default Nameservers are ns0.lcn.com for the primary, and ns1.lcn.com for the secondary. If you have changed your Nameservers in the past and would like to set them to our defaults to take advantage of our free features or web hosting packages, you can do so in your account by following the instructions below: Log in to your LCN.com account. Click the Domains icon and choose the domain you wish to manage. Click Nameservers in the Current Domain menu on the left. Click the Reset to LCN Defaults link and allow up to 48 hours for the changes to take effect. Note Your Nameserver changes will normally be noticed within a few hours, however it can take up to 48 hours for your changes to propagate globally.

How to set up name servers on Cloud hosting using cPanel

This guide will explain how to configure DNS servers within cPanel including how to register private nameservers for domains registered to your LCN.com account. For cloud hosting customers using the Vesta control panel, please click here for the relevant support guide. Let’s get started… If you want to manage DNS zones for your Cloud hosting plan using cPanel, you will need to set up name-servers to allow for this. You will first need to create 2 DNS A records pointing to the server IP address to use as nameservers – for this guide we will use: ns1.yourdomain.com and ns2.yourdomain.com. See the following guide for instructions on adding A records to domains registered within your LCN.com account. Registering Private Name-servers with LCN.com The following steps will be required if you want to apply the nameservers to the same domain name that you are using for the nameserver hostnames – for example setting nameservers for ‘yourdomain.com’ to: ns1.yourdomain.com, ns2.yourdomain.com. Each registrar may have different methods for setting up private name-servers and storing the required glue records – the instructions below will explain how to carry this out for domains registered to an LCN.com account. Go to the 'domains' section of your LCN.com account Select to manage the domain name you intend to use as the host-name for your private name-servers Select ‘edit nameservers’ Replace the existing nameserver settings with the new entries in the following format: ns1.yourdomain.com ns2.yourdomain.com Enter the IP address of your server under the IP address fields for each nameserver Select ‘update’. This completes the process required to register your private nameservers and store the glue records (IP addresses) with the registry. Configuring Private Name-servers within cPanel Select the menu for ‘Basic cPanel & WHM setup’ in the WHM control panel: Scroll to the bottom of the page where the nameserver settings for the server are located – then replace the default entries with the new nameserver hostnames you are applying: ns1.yourdomain.com ns2.yourdomain.com

Why are the DNS changes not showing on my updated domains?

All Internet hosts, including your computer when it is connected to the Internet, use a DNS server. Every time you go to a website, you need to look up the site's IP address using the domain name of the website. Your request for this lookup is eventually passed to a DNS server somewhere. However, your request is one of thousands, even millions of requests being made at any one time across the Internet. The DNS lookup process requires your local DNS server to ask others servers if it is not authoritative for the domain you are trying to reach, it should ask other servers to get an answer. Your local server could get quite busy performing these lookup requests and this could slow down its performance if it has to perform a lookup for every request. To combat this, the answers that a DNS server gets from another can be added to its own internal database and retained for a period of time equal to the time to live - (TTL) value set on the DNS record requested. Storing these responses is called caching and allows a DNS server to respond quickly to multiple queries for the same domain or host. If you are on a website and want to retrieve the next page on the site, the local DNS server does not have to look up the host again (provided the time to live value has not expired and caused the local DNS server to delete the information). This is why it takes longer to contact a website the first time, but subsequent requests for pages on the same site are faster. These are know as caching DNS servers. The DNS caches will also cache that records do not exist. Almost all Internet Service Providers (ISPs) operate some kind of caching DNS server. Although DNS caching speeds up resolution by storing recent answers, and short-circuiting the normal resolution process, there is a down side. Because DNS servers cache answers and don't delete these answers until the time to live expires, it can take hours or days for the entire Internet to recognise changes to DNS information for your domain name.

What is DNS?

All the computers connected to the internet are identified by a unique series of numbers called IP addresses (eg. 94.126.40.154). IP stands for Internet Protocol and these numbers are not easy to remember. Domains were invented because we find it easier to deal with the names, than numbers. To make it easier to connect specific computers and content, the Domain Name System (DNS) was invented. This is basically an address book which is used to map an easy to remember domain name to an IP address. This then allows any responses sent to the domain name to communicate with the computer that the IP address relates to. Using DNS is similar to making a phone call with your mobile phone. Your phone dials the number for you and the telephone network uses that number to connect you.

How to create an SRV record

Service (SRV) records are a general use records that relate to a particular service of the domain e.g. SIP or FTP. They provide flexibility to the DNS system by not having to create lots of new record types for each service. SRV records are popular for newer protocols, for example Internet telephony (SIP) or Instant Messaging (XMPP) where the desktop programs that connect to the services can find out where it is hosted and additional information such as port and protocol. One reason for creating a SRV record for your domain would be if you wanted to have a single public SIP address which could be redirected to your current location. If someone wanted to make a SIP phone call to you@domain.com the SRV record on domain.com would tell their SIP program that it should connect to sip.voip-service.com. Here's how to create a SRV record for your domain name: Log in to your account. Click the Domains icon and select Manage next to the domain you wish to amend. Click DNS Settings in the Current Domain menu on the left. Click the Add A SRV Record button. On the SRV Builder form, In the Service field enter a service name for the record e.g. sip. Select the Protocol the service uses e.g. TCP. In the Priority field enter a number for the priority of the target host, lower value means more preferred. In the Weight field enter a number for the relative weight for records with the same priority, higher values mean more weight. In the Port field enter the TCP or UDP port on which the service can be found. In the Hostname field enter the hostname of the server providing the service e.g. sip.voip-service.com. Click Add SRV Record and allow up to 24hrs for the changes to take effect. Here is a quick demonstration

How to set up a naked domain DNS record

This guide will explain how to set up a naked domain DNS record on your domain name. Adding this will allow people to visit your website without the ‘www.’ prefix. If you need to add another type of DNS record, you can learn how to do this here. Let’s get started… Login to your LCN.com account and click Domains Click Manage next to the domain name you wish to add your DNS record to Click Edit DNS Settings which is in pink and located on the right hand side of the page Under the ‘A’ Records section, click ADD AN A RECORD Leave the Hostname field blank and enter the IP Address of the server your website is hosted on Click ADD A RECORD That’s it! Your website will now load using the naked domain. All DNS changes can take up to 72 hours to complete. This may happen more quickly but this is down to the setup of your Internet Service Provider’s (ISP) network. Your browser does not support the video tag.
