The only difference is that a class C network would be 192 to 223 but a classless /24 could be anywhere in the IPv4 space.

A /24 network has the same number of usable addresses as a class C allocation, which is 254. I fail to notice how the class column (at the CIDR article) is misleading. -- Dante _______________________________________________ LinuxUsers mailing list LinuxUsers@socallinux.org http://socallinux.org/cgi-bin/mailman/listinfo/linuxusers
