One is historical reasons; old versions of the BSD code used to use all 0's as the broadcast address. Another reason is to help screen out bugs. An uninitialized value will often default to 0, so from a technical perspective it's often a good idea to avoid using 0 as a magic number, like a subnet number or such. - john romkey USENET/UUCP: romkey@asylum.sf.ca.us Internet: romkey@ftp.com "There is no loyalty except loyalty to the party.
