http://cluepon.net/ras/generate_dnsptr_generic_php A relatively simple example using php, with the net-snmp module and Net_IPv4 from PEAR. For extra bonus points, it parses your BGP state and uses any neighbor ASNs it finds for the remote side of your /30 or /31s, and it resolves point-to-point SVIs to physical ports by checking against the vlan tables. The later part was only tested on Cisco 6500s, and I haven't touched that code (or those boxes) in many many years, so no guarantees about using it on anything else. :) Out of date DNS PTRs in traceroute make baby jesus cry, so please use copiously. -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
