No, It's a short notation for the subnet mask. It means "most 24 significant bits set to 1" so, 192.168.0.1/24 means: 192.168.0.1 netmask 255.255.255.0 Oftern it's used to explicitely tell that we're talking about a single IP address: 192.168.0.1/32 Just matter of notation... -- Pietro Cerutti Non lasciar calpestare i TUOI diritti!
