Ok, I run an IRCXpro server and in that software you can mask like this:
An example:
If my IP was [email]something@123.456.789.44[/email] The software for my server make it possible to mask a host or IP like this: something@wkwjejncncxk
That means if you are an Admin you can set it the way you like, but every admin and ops will be able to see it.
Hope this help.
