AAAA Record Details

What is an AAAA record

An AAAA record (IPv6 Address Record) is used to point a domain name to an IPv6 address. For example: Point www.example.com to 2001:0db8:85a3:0000:0000:8a2e:0370:7334. When users visit www.example.com, they will be directed to the server corresponding to this IPv6 address.

Adding an AAAA record

Host Record:

• @ indicates the root domain (e.g. example.com)

• www indicates www.example.com

• Other specific subdomains

Type: Select AAAA record

TTL: 600 seconds (recommended)

Value: Enter the IPv6 address (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334)

Weight: If there are no special requirements, you can uniformly enter 1.

TTL

• TTL is the time-to-live of a DNS record in the cache of recursive DNS servers.

• The unit is seconds. A shorter TTL makes DNS changes take effect faster; a longer TTL results in a higher cache hit rate and more stable resolution speed.

• 600 seconds (10 minutes) is a common compromise that balances flexibility and stability.

Weight

The higher the weight value, the higher the proportion of access traffic allocated to it. This setting only takes effect among records of the same type.

Notes

1. Confirm that the entered IPv6 address is correct and accessible; otherwise, the website will fail to open.

2. If the server's IPv6 address changes, you need to update the AAAA record promptly.

3. If you fill in an internal private IP address, the resource will not be accessible from the public internet.
