It's actually better with IPv6 than with IPv4 because the LIR aggregate is at a multiple-of-4 boundary, so there's no need to delegate multiple zones for one address block, and it's also more likely that the RIR -> LIR delegation has been cached by the resolver. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
