<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><DIV>Randy - Thanks, you are the first person to not write this off as a "find another ISP" comment. </DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Maria, I understand your comments, but consider this... The current policy on reverse dns mapping "almost" does the job - it just needs to go a tiny bit further.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Current policy dictates that you have to map an in-addr.arpa zone for your prefix in order for your nameservers to not be considered lame.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Problem is, an AS only has to properly map a single in-addr.arpa to satisfy that requirement. What I am saying is just go a bit further, and have policy dictate that the AS must properly map ALL in-addr.arpa's for advertised prefixes in order for their nameservers to not be considered lame. Seems simple enough.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>The problem goes beyond the ISP-to-customer scenario. Take Verizon DSL, what if they didn't map the in-addr.arpa's for all their DSL IP's - thats probably 10 or so /16's easily. That would cause tons of problems for various 3rd party organizations all throughout the internet; people like vonage (sip traffic), gmail, postini, or any large smtp environment or protocol dependent on reverse DNS.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>But the current policy would not consider Verizon's reverse DNS servers as being lame. Because even though there are 1000's of in-addr.arpa zones not mapped (thereby causing excessive timeout on resolvers throughout the world), they do have one mapped to meet the minimum ARIN requirement for non-lameness. That simply doesn't make sense.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>The threat of one's reverse DNS server being declared lame is the only way to ensure proper reverse DNS mapping. I dont see why 100% enforcement across all advertised prefixes for a given AS is a problem.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Lets not forget that reverse DNS plays an important role in the proper operation of many protocols throughout the internet, and one of ARINs most important jobs is delegation of reverse dns authority. ARIN has a responsibility to make sure that the DNS server they are delegating reverse authority too is maintained to at least a minimum level of efficiency.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>-John</DIV><DIV><BR class="khtml-block-placeholder"></DIV></DIV><DIV><BR><DIV><DIV>On Sep 11, 2007, at 12:05 AM, Randy Bush wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><BLOCKQUOTE type="cite"><DIV style="margin-top: 0px;
