Dear Benoit, is there a list of communities and what it's mean? For example, community 12530:51020 means say to Golden Telecom not to announce that prefix to C&W (see whois AS12530). Some ISPs publish this info on RIPE DB (like AS12530), but is there a place for publish these communities? Often it is very useful to make some ISP to accept certain way to your network, even if this ISP is in three-for hops from your upstream.
