Step-by-step instructions for connecting your 123-reg domain to WedSites.
​

If you registered your domain with 123-reg, follow these steps to add the DNS records needed to connect it to your WedSites wedding website.
​

Make sure you've added your domain to WedSites first. Go to Settings > General and enter your custom domain, then save. Then come back here to set up your DNS records.
​

You'll need access to your 123-reg control panel. Make sure you can log in and that you have permission to manage DNS for your domain.
​

You'll be adding these two records to your 123-reg domain:
​

Important: Which records you need depends on your domain. If you're using an apex domain (like yourwedding.com), add both records so that yourwedding.com and www.yourwedding.com both work. If you're using a subdomain (like wedding.yourwedding.com), add the CNAME record only — the A record would point your whole domain at WedSites, which isn't what you want.
​

Go to 123-reg.co.uk and sign in to your control panel.
​

Look for any existing A records in the list.
​

If you see existing A records for @:
- You need to delete any A records that don't point to 37.16.10.26
- Having multiple A records causes your domain to only work sometimes
- Click the Delete or Remove button next to each conflicting record
​

Common conflicting records to look for:
- 123-reg default parking page A records
- Website builder A records
- Old hosting A records
​

Using a subdomain like wedding.yourwedding.com? Skip this step. Your domain only needs the CNAME record in the next step.
​

Using a custom subdomain? If you're using something like wedding.yourwedding.com instead of www, replace "www" with "wedding" in the Hostname field. This is the only record you need for a subdomain.
​

After saving, check the DNS records list to confirm both records appear:
- An A record for @ pointing to 37.16.10.26
- A CNAME record for www pointing to domains.wedsites.com
​

Wait for DNS propagation. 123-reg DNS changes typically take 15 minutes to 24 hours to fully propagate.
​

SSL certificate is automatic. Once your domain connects, we'll automatically add an SSL certificate so your site works with https. This happens within a few hours of your domain connecting.
​

Test your domain. After waiting, try visiting your domain in a browser. You should see your wedding website!
​

Domain not working after several hours?
- Double-check that you entered the DNS records exactly as shown above
- Make sure you deleted any conflicting A records
- Check that you entered your domain in WedSites under Settings > General
​

Still seeing 123-reg parking page?
- Delete all default A records for the root domain
- Check if your domain has a website builder connected and disconnect it
- Try clearing your browser cache or testing in incognito mode
​

Can't find DNS management?
- Go to Domain names > click Manage next to your domain > scroll to Advanced domain settings > Manage DNS
- If you don't see this option, your domain may be using third-party nameservers — check the nameservers section first
​

CNAME issues?
- Make sure the Hostname is "www" and not "@"
- Verify the Destination field is exactly: domains.wedsites.com
- Check that you don't already have a CNAME for www — delete the old one first
​

Need to verify DNS setup?
- Go to dnschecker.org
- Enter your domain and select "A" record type
- You should see 37.16.10.26 in the results

UK-focused registrar: 123-reg is the UK's largest domain registrar. Their interface and support are geared toward UK customers.
​

Website builder conflict: If you're using 123-reg's website builder, it manages DNS automatically. Disconnect or deactivate the website builder before adding custom DNS records.
​

Nameservers: For DNS records managed through 123-reg to work, your domain must use 123-reg's nameservers. If you've changed nameservers to another provider, manage DNS there instead.
​

Email hosting: If you use 123-reg for email, your MX records are separate and won't be affected by adding these A and CNAME records.
