how to add a new address range on Webmin

Help! (Home for newbies)

Hello brothers

I got a new IP-address range from my host.

It looks like this (I edited 128 numbers):

ex: 190.167.218.128/25

Primary IP Address: 190.167.218.129
Usable IPs: 190.167.218.129 - 190.167.218.254

So they say I have 1 broadcast IP, 1 gateway and then 126 IPs I can use for websites.

I’m inside “Create Address Range” in Webmin and there is 6 fields I need to fill in.

  1. Interface description
  2. Real interface
  3. Range name
  4. Starting address
  5. Ending address
  6. First virtual interface no.

Can anyone please explain how I should fill these out?
I have no idea what I should fill in “Range name” for example.
