How do I set up a SRV record on my domain?

This article will show you how to add a SRV Record to your domain name.

A SRV record is a DNS entry that specifies information about a service that is available on your domain, most important, being the location of the service inside that domain.

To set up a SRV record on 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 7

Start by logging in to your 123 Reg Control Panel.

Step 2 of 7

Next, select Manage All opposite Domains within the ‘All Products and Services’ section.

Step 3 of 7

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?

Step 4 of 7

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.

Step 5 of 7

If you’re using our legacy Control Panel, select the Advanced DNS tab near the top.

Step 6 of 7

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

  1. Type: choose SRV from the list.
  2. Service*: the symbolic name for this record, which can be either _ldap, _ftp or _smtp.
  3. Protocol*: the transport protocol for this record, which can be either _tcp or _udp.
  4. Name*: enter @ to use this record on your root domain, or enter a prefix like mail.
  5. Value/Hostname: this specifies the name of the server providing the service. This can be either your-domain-here.co.uk. or you can take the domain away to show just _sip.
  6. Priority: the prominence the record gets given. This can range from 0 to 65535, with 0 being the highest priority.
  7. Weight*: the relative weight for SRV records with the same priority. A higher weight increases the likelihood of it being chosen.
  8. Port*: the port where the record can be found.
  9. 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.
  10. Destination SRV**: where the traffic is being sent to. This should show the Weight followed by the Port and then the domain name, all of which must be separated with a space. For example: 1 5061 your-domain-here.co.uk.*Field only appears in our current Control Panel.
    **Field only appears in our legacy Control Panel.
Step 7 of 7

Once you’ve done this, click Save or Add to create your new SRV record.

Please note: it will take between 24-48 hours for any DNS records to become active, provided you didn’t also change the nameservers.

Additionally, some services will require multiple SRV records to be created:
