Pointing a 123-reg registered domain at your BigCommerce store

If you have bought a BigCommerce site through us then as a reseller we will complete this process for you if you wish at no charge.

Ok so you’ve registered your domain name with 123-reg and you now want to point it at your new BigCommerce store.  Where do you start?

Well first a little background, to find your webpage on the WWW, this daisy chain occurs:

Registrar info -> Name Server info -> DNS info -> Locates your hosting -> Serves a webpage

Registrar’s setting

As 123-reg are your domain’s registrars they control the setting that says where your name server is.   There is a menu option on 123-reg to change the name server.  You can change this to whatever  BigCommerce tells you is the setting for your shop.

Name server

Every site has a name server – this tells everyone where your website and mail server information (DNS) can be found. The setting you’ll find probably look like or similar to this:

ns.123-reg.co.uk [required]
ns2.123-reg.co.uk [required]

These are BigCommerce settings for 123-reg

ns1.bigcommerce.com [required]
ns2.bigcommerce.com [required]
ns3.bigcommerce.com [optional]

123-reg has a menu option to change your name server (i.e. the NS setting) in the control panel. These setting will probably be, the same as above, however your e-shop documentation will tell you the BigCommerce settings

Once the Name server is set up, you can then set up the DNS on that name server to point to your web and mail servers.

Setting  the DNS.

This holds the IP address etc of your mail and web servers.  Currently the DNS is at 123-reg, and points www.yoursite.co.uk to my hosting server or a 123-reg default

Current settings  for my website hosting will be:
yoursite.co.uk A
*.yoursite.co.uk A

These are your example settings for a website shop at BigCommerce whose IP address is

yoursite.co.uk A
www.yoursite.co.uk CNAME yoursite.co.uk

The above line just says  http:/www.yoursite.co.uk is the same as https://yoursite.co.uk, i.e. AKA BigCommerce.

Below are the settings should you wish to use our email server (  You need to add/change them in BigCommerce’s DNS if you change the nameserver to them.

“yoursite.co.uk” is the 123-reg fully qualified host name

yoursite.co.uk MX 10 webmail.yoursite.co.uk
yoursite.co.uk MX 20 webmail.yoursite.co.uk
webmail.yoursite.co.uk A
