Subdomains on IP addresses in Webmin

Question

How can I set up a subdomain on an IP address using Webmin?

So, if I go to http://directory.127.0.0.1/ it goes to the same place as http://directory.localhost/ (/var/www/directory)?

Answer 1

That's not how IP addresses and host names work.

You have either an IP address, which can consist only of digits, or a host name, whose components cannot consist only of digits. Host names can have subdomains, IP addresses can't.
