I have a domain with another company can I use it with 123 Reg hosting?

This article explains how to use the Domain Mapping feature to map a domain name registered with another company (external domain) to a 123 Reg hosting package.

Alternatively, you can contact your domain registry and change your DNS settings there, by pointing them to your 123 Reg Hosting package.

If you’d rather map an external domain to your hosting, you will first need to add the domain to your domain management pool, please follow the below instructions.

Please note: if you purchased your hosting package after July 2020, please follow the steps for Add-on Domains as outlined in this article.

Any packages that were purchased after March 2015 but before July 2020 do not support this feature.
