A records (address records) define the mapping between a fully qualified hostname and its IP address. This mapping allows users to type in sensible names for your servers such as www.yourdomain.com, rather than having to remember a more complex IP address assigned to that server.
For example, you may wish to add an A-record for the hostname ‘www’ and IP address 220.127.116.11, so that www.yourdomain.com resolves to the IP address 18.104.22.168 where your website is hosted.
To add an A record, you must log into your control panel and select your domain name under “Hosting” on the left hand side.
Following this, within the main control panel select the “Domains” tab and click on the domain you wish to add the A record to. Then select the “Add A record” tab so that you can add the details of the A record.
