Just wondering, as I have about IPv4 anycast allocations: why can't we designate a block for microallocations, within which prefix length filters aren't applied? The number of routes in the DFZ is the same either way; is there any technical reason why /64 or /128 prefixes, or /32 in IPv4, can't be used? I'm not a routing person, so apologies if this is somehow unspeakably dumb. -zefram
