The IPv4 Address Record is the most basic and the most important DNS Record type. They are used to translate human friendly domain names such as yourdomainname.com into IP-addresses such as 1.2.3.4 (machine friendly numbers).
There you would find 3 fields:
- Host Name: Here the domain name, for which you are adding the A Record for, would be pre-filled (e.g., yourdomainname.com). Now, if you wish to add an A Record for my.yourdomainname.com, then you would have to put in my the text box. If you wish to add A Record for just yourdomainname.com, then you can leave this box blank.
- Destination IPv4 Address: Here you would have to enter the IPv4 IP Address of the Web Server, where you wish to host this domain name.
- TTL: This is the Time To Live for this Record, in seconds. Any Server which once queries this Record will query it again after this time interval. The ideal TTL is 86400, which is 1 day. It can not be set to less than 14400, i.e., 4 hours.
