On Fri, 06 Sep 2002 at 15:42 GMT, gazing longingly at the horizon, Yancey B. Jones <[email protected]> felt a deep, passionate desire to let the following be known: > Now I see...

A netmask of 255.255.255.0 is the equivalent of 24 bits in a row (three octets, the fourth is zero). A netmask of 255.255.255.128 would be denoted by one additional bit (the most significant bit in the last octet is set), so it would be written as /25. An A-class subnet with a mask of 255.0.0.0 would correspond to /8. See f.ex. <http://www.telusplanet.net/public/sparkman/netcalc.htm>. hth. -- Time flies like an arrow, fruit flies like a banana.
