Not often. Few people are actually supernetting within a given broadcast domain. There's still an awful lot of hardware that doesn't work right in that environment. The larger problem is that subnetted /24s still are wide open. This kind of filter won't block anything from their broadcast addresses, since they're not the .255 address. -- -- Karl Denninger (karl () MCS Net)| MCSNet - Serving Chicagoland and Wisconsin http://www.mcs.net/ | T1's from $600 monthly / All Lines K56Flex/DOV | NEW!
