A company with an old style Class B (/16) wants to be multihomed and split their incoming load between 2 ISPs (outgoing they can live with going via 1 and if the primary fails they fallback to the secondary conenction). In order to split the load on incoming, one ISP has to announce a /17 and the other ISP has to announce a /17 (or even the entire /16). But since this net is from the 147.x.x.x range, various ISPs around the globe will filter out the /17. This means that having a /16 from the 192.x.x.x range is better (these days), unless someone can show me a solution. Thanks, Hank
Hank, since RIPE has been assigned 62.0.0.0/8 and RIPE started to assign allocations ranging between /16 to /19 to Local Internet Registries (i.e. ISPs) througout Europe, the problem regarding filtering prefixes greater than /16 out of the Class A range will be addressed fairly soon, I guess.
