You're assuming that there can be but one subnet per netmask. The netmask There are 16 subnets in 172.0.0.0 to 172.255.255.255 that have netmask 255.240.0.0. The netmask determines how many bits of the address are allocated to determinining the network address: it does not determine the values of those bits. dc _____________________ David Coder SysAdmin WebHosting Verio.com 703-749-7955 x1314 > ..................................
