hi,
i have a Reseller web hosting website. some of my clients wants to use my service domain to create third level domains of their own. how can i do it?

u can create third level domain based on second level domains and this have same features as second level domains. Customers can use your service domain to create third level domains of their own. For instance, if your second level domain is xyz.com, your customers can create domains like illustrative.xyz.com.

Third level domains are registered on your DNS server and need no domain registration company to be registered.

To add a domain for third level hosting, you need to create a DNS zone and allow third level hosting in the zone settings.

how can we set up our corporate site?

for set up your corporate site:

1. Make sure you have a service DNS zone
2. Create a service plan
3. Disallow signups from outside your admin account.
4. Create a service account
