Use your existing 123 Reg domain on OfferingTree

Connect your 123-reg domain to your OfferingTree site by updating your domain's DNS settings. This allows you to maintain ownership of your domain and continue to renew it directly through 123-reg. You will continue to be responsible for paying for your domain through 123-reg.

Here's how:

1. Log in to 123-reg: Go to 123-reg.co.uk (or your appropriate 123-reg regional site) and log in to your account.

2. Manage Domains: Navigate to the section for managing your domains. This might be called "My Domains," "Domain Management," or similar.

3. Select Your Domain: Choose the domain you want to connect to OfferingTree.

4. Advanced DNS Settings or Edit Zone File: Look for a section called "Advanced DNS," "DNS Management," "Edit Zone File," or similar. You'll need access to the advanced DNS settings.

5. Add/Edit DNS Records: You'll need to add or edit two records:

   • WWW CNAME Record:

     • If a CNAME record for "www" exists: Find it and edit it.
     • If a CNAME record for "www" doesn't exist: Add a new record.
     • Type: CNAME
     • Host/Name: www
     • Value/Points to/Target: customdomains.offeringtree.com

   • @ A Record (for your root domain):

     • If an A record for "@" or your root domain (e.g., yourdomain.co.uk) exists: Find it and edit it.
     • If an A record for "@" or your root domain doesn't exist: Add a new record.
     • Type: A
     • Host/Name: @ (or your root domain)
     • Value/Points to/IP Address: 35.209.110.2

6. Save Changes: Save the changes you've made to the DNS records.

7. Check your DNS: Back in OfferingTree, open Site Settings → Domains and click Check my DNS. Your site goes live on its own a few minutes after your records are saved — there is no need to contact us. For the full walkthrough, see How To Get Your Own Custom Domain.

Important Notes for 123-reg:

• 123-reg Interface: 123-reg's interface might vary slightly. If you have trouble finding the correct settings, consult their help documentation or contact their support.
• Zone File vs. Individual Records: 123-reg might present your DNS records in a "zone file" format, or they might allow you to add/edit individual records. The principles are the same; you just need to locate the correct place to add the CNAME and A records.
• Propagation: After saving your DNS changes, it can take some time for them to propagate across the internet. Be patient.
• Support: If you have any trouble, contact 123-reg's customer support for assistance. They are the best resource for questions about their specific interface.
• Root Domain: The "@" symbol often represents your root domain (e.g., yourdomain.co.uk). Some providers might use a different way to indicate the root domain, so check their documentation or contact support if you're not sure. They might recommend setting up a redirect for the root domain to the www subdomain.
