/24 if only
heck, why not /32?
Filtering on /32 shouldn't be a huge problem. I count 4 294 967 296 /32's. That's the upper limit and it's really not that much. If we did permit /32's, a router could for instance aggregate incoming chunks of matching netblocks into fewer ones in order to decrease workload and memory usage etc... Without thinking too hard, this number is also the same if we filter on /32 with IPv6. But we are talking about filtering on /48 these days so that's a bigger challenge. Permitting /32 would atleast solve the problem with anycast. Joergen Hovland
