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: 212.67.202.5
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:
Start by logging in to your 123 Reg Control Panel.
Next, select Manage All opposite Domains within the ‘All Products and Services’ section.
You will now see a complete list of your purchased domain names. Select the domain you want to update from the provided list.
If you can’t find your domain in this list, you may be able to find it on the Domain Name Overview page within our legacy Control Panel. For more details on this, please read the following article: How do I access and manage my products?
If you’re using our current Control Panel, select DNS in the navbar and continue to step 6.
If you’re using our legacy Control Panel, scroll down to the Advanced Domain Settings section and select Manage DNS.
If you’re using our legacy Control Panel, select the Advanced DNS tab near the top.
On the next page, create a new record with the following information:
- Type: select AAAA from the list
- Name/Hostname: enter www
- Value/Destination IPv6 address: enter the IP address the domain will point to
TTL: how long the record takes to resolve. This should be measured in seconds, for example, one hour equals 3600 seconds, so your TTL would be 3600. We recommend leaving this as Default.
Once done, click Add or Save to complete the process.
Please note: it will take between 24-48 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.
