AAAA record configuration setting www to 2600:1800:5::10
A record configuration setting the wildcard to 2600:1800:5::11
The end result is all traffic going to www.example.com will point to 2600:1800:5::10, whereas, all traffic requesting any other (unspecified) hostname will point to 2600:1800:5::11.
Best Practice Tip:If you plan on changing your IP you should set your TTL to a low value a few hours before you make the change. This way you won’t have any downtime during the change. Once your IP is changed you can always raise your TTL to a higher value again.
