Hi, I can see there are some routes registered in RIPE for prefixes under administration of different RIRs. For example https://apps.db.ripe.net/search/lookup.html?source=ripe&key=23.59.96.0/20AS20940&type=route The 23/8 is an Arin address space. I'm wondering what is the recommended approach for registering routes related to non-RIPE prefixes: -to register them only in RIPE (because of the security mechanisms implemented for RIPE database objects?), -to register them in both RIPE and appropriate (according to IANA http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xhtml) RIR (probably not because of extra effort required and the risk of data inconsistency) -or register only in the RIR appropriate to the IANA address space and not to register in RIPE BTW I recently started using http://irrexplorer.nlnog.net and according to its logic route registered in RIPE for non RIPE prefix is OK (not perfect, but OK - displayed with green label). Are there any other tools that help to verify whois/irr data accuracy?
