DNS AAAA records map hostnames to IP addresses of hosts (computers) on the Internet, the same way DNA A records do. The fundamental difference between the two resource records is that the DNS AAAA map 128-bit IPv6 addresses (e.g. 2001:19f0:5:3c8c:5400:1ff:fe6f:aa02), whereas DNS A map 32-bit IPv4 addresses (e.g. 220.127.116.11). Since the IPv6 addresses are lengthier, they can accommodate more addresses than IPv4 addresses.
DNS AAAA record requires three inputs:
DNS AAAA records can map IPv6 addresses only, whereas the DNS A records map IPv4 addresses. For example, "2606:2800:220:1:248:1893:25c8:1946" is the IPv6 address of "example.com" hosted using a DNS AAAA record. Also, certain IPv6 addresses like local and reserved IPv6 address ranges, are not recommended to be hosted using DNS AAAA records.
DNS records are hosted on the Internet through DNS hosting services. If you are using Slickalpha DNS, check this related guide to learn how to add a DNS record on your Slickalpha account.
DNS records can be queried directly on your system terminal using the dig command. To check your DNS AAAA records on the browser, try our free DNS Lookup tool.
DNS AAAA records are essential in mapping IPv6 addresses of hosts to hostnames. Since IPv4 addresses are limited in range, IPv6 addresses may complement host connections on the Internet.
