Good catch Yeah, but you cannot really subnet that way: [angenenr at shutdown ~]$ipcalc.pl 192.168.0.16/255.255.255.224 Address: 192.168.0.16 11000000.10101000.00000000.000 10000 Netmask: 255.255.255.224 = 27 11111111.11111111.11111111.111 00000 Wildcard: 0.0.0.31 00000000.00000000.00000000.000 11111 => Network: 192.168.0.0/27 11000000.10101000.00000000.000 00000 HostMin: 192.168.0.1 11000000.10101000.00000000.000 00001 HostMax: 192.168.0.30 11000000.10101000.00000000.000 11110 Broadcast: 192.168.0.31 11000000.10101000.00000000.000 11111 Hosts/Net: 30 Class C, Private Internet Ralph -------------- next part -------------- A non-text attachment was scrubbed...
