For those who have to calculate subnet masks and available ip addresses given an ip address and netmask, check out a free command line utility which will do all the math for you. Feed it an ip address and decimal subnet mask or cidr mask and it calculates the network address, broadcast address, first and last available ip's and the net mask. This little gem is a real lifesaver for network admins. Check it out at :
