This answer will explain how the 123-reg DNS management system works and how to use it.
DNS management allows you to control the servers your domain and email addresses point to. You can manage the DNS of the domains registered with 123-reg in the Manage DNS section of your control panel.
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.

In the Domain names section, select the relevant domain name in the drop-down list and click on the Manage button.

Click on the Manage DNS link.

You will now see the DNS management screen. From here you can add/remove A records, CNAMES and MX records.
Please note: 123-reg DNS Management does not support the following:
- SRV
- DKIM (DomainKeys)
- PTR (Reverse DNS)

You need at least one MX record, or no email will be received. If this MX record points to a subdomain (e.g. mail.mysite.co.uk), ensure there is a valid DNS A or CNAME for that record.

Click on the Update DNS button to save your changes
The @ record relates to the blank A record for the domain with nothing before it i.e. yourdomainname.co.uk.
The * A or CNAME is a "wild card" and will be used for subdomains that you have not defined above. The * entry must appear as the last one in the list.
Please note: It will take between 24 - 48 hours for the new DNS records to become active.
