How can I add an IPv6 record (AAAA Record) to my Domain Name?

This guide will outline the difference between IPv4 and IPv6 records, and how you can add IPv6 records to your domain name.

If you’re not sure how to tell the difference between IPv4 or IPv6 records, here’s how:

A v4 address looks like this:

A v6 address will look like this: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

To add an IPv6 record to your domain name, you’ll first need to ensure your domain is pointed to the 123 Reg nameservers. Otherwise, any configurations you’ve made to the DNS through our Control Panel will not take effect.

You will need to set your DNS at your nameserver provider. For more information on how to do this, 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 any new nameserver changes to become active.

Once you’ve done this, simply follow these instructions:

Step 1 of 6

Start by logging in to your 123 Reg Control Panel.


Step 2 of 6

From there, select Domain Names within the ‘Manage active products’ section.

Next, choose your domain name from the provided list and then select Manage.

Manage Domain Names


Step 3 of 6

From there, select your desired domain from the drop-down menu within the Manage Active Products section and click Manage.

Alternatively, you can scroll down to the Domain names section and select the relevant domain name from the drop-down menu. Once selected, click Manage.

Select Manage


Step 4 of 6

Scroll down to the Advanced Domain Settings section and click Manage DNS.

Click Manage DNS



Step 5 of 6

Select the Advanced DNS tab near the top.


Step 6 of 6

On the next page, create a new record with the following information:

  • In the Type field, select AAAA from the drop-down list
  • In the Hostname field, enter www

In the Destination IPv6 address field, enter the IP address the domain will point to

Once done, click Add to save the new record.

Please note: it will take between 4-8 hours for any DNS records to become active, provided you didn’t also change the nameservers.

If you already have an existing IPv4 with the same Hostname, you will need to remove this from the DNS settings, as the IPv6 record replaces the IPv4 record.
