Thanks everyone. How about this then from page 4, about class A networks: "Each Class A network address has an 8-bit network prefix, with the highest order bit set to 0 (zero) and a 7-bit network number, followed by a 24-bit host number... A maximum of 126 (27 -2) /8 networks can be defined. The calculation subtracts two because the /8 network 0.0.0.0 is reserved for use as the default route and the /8 network 127.0.0.0" 12^6? Is 27 - 2 supposed to be 128 - 2? Kendall
