What are AAAA (IPv6 Address) Records?
AAAA (pronounced quad A) records map an FQDN (fully qualified domain name) to an IPv6 address. Similar to an A record, but operates exclusively over the IPv6 protocol.
AAAA Record Fields
|A) Name||This will be the host name for the record, typically a computer or server within your domain. It is important to note, the domain name is automatically appended to the “Name” field of the record. For example, defining www.example.com in DNS would be creating an A record with the name field of “www” within the example.com domain. If the “Name” field is left blank, it represent the root record of the domain. The root record for the base domain can also be referred to as the apex record and is represented in a @ symbol in some documentations.|
|B) TTL||The TTL (Time to Live) in seconds is the length of time the record will cache in resolving name servers and web browsers. The longer the TTL, then remote systems will lookup the DNS record less frequently. Your nameservers will also receive less query traffic since most queries are answered by resolving name servers. Conversely, the shorter the TTL the faster any changes you make to your DNS will propagate in servers that have cached data. However, your domain will receive more query traffic.
Records that are static and don’t change often should have TTL’s set between 1800 (being on the low end) to 86400 seconds (30 minutes to 1 day cache).
Records configured with Failover or that change often should have TTL’s set anywhere from 180 to 600 (3 to 10 minutes cache).
If a change is needed for a record with a high TTL, then the TTL can be lowered prior to making the change and then raised back up again after the changes were made.
|C) Record Mode||The Record Mode is how you enable settings like Failover, Record Pools, or Round Robin with Failover. You can read more about these settings here.|
|D) IP||The IPv6 address of your FQDN. An IP (Internet Protocol) address consists of a four octet 32-bit address.|
|E) Notes||Add a helpful note with keywords so you can search for your records later.|
|F) Save||Save your record changes and don’t forget to commit your changes after you’re done making record changes for this domain!|
Video Tutorial: How to Add, Edit, and Delete Records
ADD A AAAA RECORD
4. In this screen, you will add the record information. Follow the steps below:
A) Name: Enter an identifiable name for your record.
B) TTL: Edit the TTL. Time to Live is measured in seconds and is the amount of time the record will cache in resolving name servers and web browsers.
C) Record Mode: The Record Mode will be left at Standard for this tutorial. Please note, the other Record Mode options are covered in different tutorials.
D) IP Address: Enter the destination IPv6 address for the host.
E) Note: Add a helpful note with keywords so you can search for your records later.
F) Save and Close: Save your changes. Don’t forget to commit your changes.
Information on the NX Domain feature can be found in the Disabling a Record tutorial.
EDIT A AAAA RECORD
3. Under the AAAA Records section, select a record by clicking the check mark next to it, then click the icon to edit a record.
Please note, you can not edit a record that has not been committed following its creation.
DELETE A AAAA RECORD
3. Under the AAAA Records section select a record by clicking the check mark next to it, click the icon to delete a record.
Please note, you can not delete a record that has not been committed following its creation.
4. The record will now show as strike through text, and is now in the queue of changes to be committed.
