Restriction: This feature is available only in Enterprise groups.

Groups.io typically recommends that an Enterprise group use a subdomain for the group instead of a top-level domain (for example, groups.example.com rather than example.com). Using a subdomain for the group gives your organization more flexibility because you can continue hosting the top-level domain with your current provider, leaving any existing content in place. 

To set up a custom subdomain:

1. Decide which subdomain you want to use for the group.
2. Contact your domain registrar and ask for their assistance (or look for instructions on their website) in adding two name server (NS) record settings for the subdomain. The NS records should look like these examples:
   • groups.example.com in NS dns1.groups.io
   • groups.example.com in NS dns2.groups.io
     ! Important: Do not change the DNS servers of your top-level domain.
3. After the domain’s NS records are changed, contact Groups.io Support and provide:
   • The name of the Enterprise group
   • The subdomain name

Groups.io Support then takes the necessary steps to complete the subdomain setup.
