Classic was designed to use the "chomp" command in the banning areas to save code and time. One of the things to remember when banning in the stock classic program is that you need to be very careful on what you ban.
Example: (Unless patched, I doubt it.)
If you ban the following:
mail.com
you also ban the following:
hotmail.com
gmail.com
snailmail.com
Pretty much anything that has the "mail.com" in that order in it
In the IP banning the example was used as 243.21.31 and 243.21
Same here from my experience so the following would be banned using an entry as 243.21.31
*.243.21.31
or
243.21.31.*
You don't need the wild card but this will indicate what how and where it will look using the stock banning system written with the chomp routine.
I hope this helps someone to understand how it works.
P.S. Hello Dave Dreezer, long time no see. How have you been?
