Mod to block IP addresses?

[PinkLiquorice]

<font size="3">I have had a look at my ban members and it doesnt have an option to ban specific IP addresses as well as that a member by name, am I being blind or is there a mod that can do this, I cant search for IP address ban on here as its too little letters to add IP. If someone could point me in the right direction or help me out I would appreciate it

Thanks!</font>
