Is that correct? : :If the above is correct, why is the IP address supplied above correct? The first address in a subnet (any subnet, from a /8 to a /30) is the network address. In 4.2 BSD it was also the braodcast address. The rest of the world, including BSD 4.3 and later use the last address in a subnet as the broadcast address. I don't think windows supports 4.2 BSD compatibility, so the above error is perfectly valid. Jamie Bowden -- If we've got to fight over grep, sign me up.
