The A-record is the most basic and the most important DNS record type.
They are used to translate human friendly domain names such as "www.clickit.no" into IP-addresses such as 1.2.3.4 (machine friendly numbers).
A-records are the DNS server equivalent of the hosts file - a simple domain name to IP-address mapping.
You can use the A-record in the normal form or the raw form on our servers. The format in which to enter the data is as follows:
Standard form:
www A 1.2.3.4
@ A 1.2.3.4
Raw form:
www 43200 A 1.2.3.4
@ 43200 A 1.2.3.4
Where 'www' is a subdomain and '@' is the root zone name. 43200 is the TTL in seconds.
