Bukkit

I need also to block/replace all addresses which are like x.y for example google.com but not http://google.com and www.google.com

basically i use the host name and just add it to the list of not allowed words as minecraft by default strips the . from URLs anyway.

I didn't understand, how can I block ALL minecraft server hostnames ?

basically had to just add hypi, plex and others manually since people will bypass a url filter by saying Lets go to Hypixel!

Hum... anyway there are not so much servers with hostname.
Can it blocks IP like that ? =>
123 . 123 . 123 . 123
12 3.12 3.12 3.12 3
123 123 123 123
123(.)123(.)123(.)123
123p123p123p123
123-123-123-123
etc...

Can you please block IP like that ? =>
123 . 123 . 123 . 123
12 3.12 3.12 3.12 3
123 123 123 123
123(.)123(.)123(.)123
123p123p123p123
123-123-123-123
etc...
