How do I change the IP address for an external domain?
This article will show you how to change the IP address for a domain name that isn’t hosted with 123 Reg.
If you have a domain name that’s registered with a third-party provider, such as Fasthosts and Ionos, and need to update the IP address associated with it, simply follow the instructions outlined below.
Please note: these steps will vary depending on which hosting provider you have chosen.
It will also take between 24 – 48 hours for any nameserver changes to become active.
Start by logging in to your third-party account.
From there, find the page for your domain name’s DNS records. Depending on who your provider is, this may be titled ‘DNS Management’, ‘Name Server Management’ or ‘Additional Settings’.
Find the A record for your domain (represented by the Hostname or Host Record ‘@’) and select the Edit or Amend option that appears opposite it.
Change the provided IP address (represented by a series of numbers separated by full stops, like ‘12.34.567.890’) to your preferred value.
You will also need to update the IP address for each subdomain associated with your domain. These will be A records that typically feature the prefix ‘www’.
If you don’t have any subdomains, we recommend that you create a new A record for your domain using the following details:
- Name: www
- IP Address: this must match the IP address for your ‘@’ A record
- TTL: leave as default value
Once done, be sure to Save your changes.
You’ll then need to wait until your DNS changes become active, which can take anywhere between a few minutes to up to 48 hours.
