DNS (Domain Name System) is a service that translates domain names into IP addresses. DNS is useful because a domain name such as example.com is a lot easier to remember than an IP address which is are always in the same numerical format, for example 123.145.167.189.
You would need to use DNS if you have a domain name that is not pointing to the correct location, for example if you have a domain name with Elite and you want to point it to a hosting package with another provider, you would need to make changes in your DNS record to ensure that the domain is pointing to the right place.
DNS records are stored in a zone file; this is where the record information for your domain is stored and enables you to check that your domain is pointing to the correct server or mail server.
Elite supports the following types of records:
Address Records or A Records are used to point a domain name or subdomain name to a specific web space using an IP address.
CNAME or Canonical Name allows you to point one domain or subdomain to another domain name for example the CNAME for www.example.com could be www.thisisanexample.com. This means that when you go to www.example.com it will check the DNS records for www.thisisanexample.com and point you there.
TXT records are used to add text into a DNS record. This is usually used to add extra rules or for formatting the domain.
SPF record or Sender Policy Framework record is an email validation system.
MX record is also known as a Mail Exchanger record and are used to direct email to the correct mail server.
