This article explains how you can arrange for a IPV6 record(s) to be added to your Domain Name.
Example:
A v4 address looks like this : 212.67.202.5
A v6 address will look like this : 2001:0db8:85a3:0000:0000:8a2e:0370:7334
Firstly, you need to ensure your domain is pointed to our nameservers:
- ns.123-reg.co.uk
- ns2.123-reg.co.uk
If the domain is not pointed to the 123-reg nameservers, you will be unable to manage them from the 123-reg control panel.
For more information on changing your nameservers please view the following article:
How do I change the nameservers for my domain name?
Please Note: It will take between 24 - 48 hours for the new DNS records to become active.
