The .42 was just a valid IP in the range determined by your subnet mask. As stated above by [jedi] 29 bits are network and 3 are host. Your host range is .41 through .46 and .42 is a valid host IP. EG 11000000.10101000.00000001.00101010 192.168.1.42 11111111.11111111.11111111.11111000 255.255.255.248 or 29+3 11000000.10101000.00000001.00101000 192.168.1.40 (after AND op) Make more sense?
