@casino Let’s assume that www.my-cable-modem.net resolves to IP address 192.168.100.1. If you put 192.168.100.1 in the black list, then http://192.168.100.1 is blocked. However, http://www.my-cable-modem.net is not blocked. That’s the way it should work because multiple web sites may be hosted on the same IP address and you only want to block the domains listed in the black list.

There may be occasions you want to block an IP address, no matter what name is used to access it. That’s when you want to use the forced block syntax: “192.168.100.1!”. When an exclamation mark is appended to the end of the IP address, all domains that resolve to the IP address are also blocked (e.g., www.my-cable-modem.net).
