I operate a small WHM account, mostly for my own personal use and a few friends. I would like to host a few friends, but they don't have a domain name. Is it possible to set a user up in WHM that doesn't have a domain name? What's the best method for doing this? Any help is appreciated!

Thanks

You can setup a subdomain sub.yourdomain.com. It's just as you would setup a regular account with the exception of the subdomain as the main 'domain'.

You could also just enter a domain name and never actually tell them the domain name and just issue them the IP link.
