Then (taking into account the RIR's previous experience with glue records and the resounding lack of people caring about the reverse tree etc), what would be the 'best' way of doing this? The RIR's current procedures for obtaining delegation information are simply 'range, nameservers' (in one form or another). Asking the RIRs to supply glue with the delegation implies an extra step, with accompanying onus, being one of: Nameserver IPs collected at time of request, onus on client/requestor to ensure that they are kept up to date. or RIR automagically keeps track of IP address changes applicable to nameservers referenced as glue, with onus on RIR to keep this magic running (assume normal DNS refresh times are involved here, so a change to a glue nameserver would be reflected in the RIR's glue a short (Listed-DNS-refresh-time+Listed-RIR-zone-rebuild-time) time later ). or (current) RIR does not supply glue records, relying on the visibility of the forward tree for delegations to work. Choose one, you can't have all three ;) -- Bruce Campbell <bruce.campbell@apnic.net> +61-7-3367-0490 Systems Administrator APNIC
