What is a "A" record?


An "A" record, also called an "address" record, links a human readable name (e.g. to a computer IPv4 address.

There are three values that must be specified for an A record:

  • Name - The host name of the record (e.g. www)
  • TTL - The time of live, if not specified the default for the zone will be used
  • IP - Indicates the IP which this record is mapped to. For example,

DNS-Engine supports multiple IPs per host name for routing and round robin.

Whats the difference between an A record and an AAAA record?

Both A and AAAA records are equally important when it comes to resolving DNS queries, however the difference is that an A record resolves IPv4 Addresses and an AAAA record resolves IPv6 addresses.

If your host device only has an IPv4 address then you only need an A record.  If the host has bound to it both IPv4 and IPv6 addresses then you could use both A and AAAA records.
