<DIV style="MIN-HEIGHT: 14px; MARGIN: 0px"><BR></DIV>
<DIV style="MIN-HEIGHT: 14px; MARGIN: 0px"><BR></DIV>
<DIV style="MARGIN: 0px">Rationale:</DIV>
<DIV style="MIN-HEIGHT: 14px; MARGIN: 0px"><BR></DIV>
<DIV style="MARGIN: 0px">Current policy only considers an Org's delegation
being deemed lame if</DIV>
<DIV style="MARGIN: 0px">all of in-addr.arpa zones for a given name server
of a specific network</DIV>
<DIV style="MARGIN: 0px">registration are lame. Lame is defined when ARIN
tests an in-addr.arpa</DIV>
<DIV style="MARGIN: 0px">zone by requesting the SOA record from the name
server registered in</DIV>
<DIV style="MARGIN: 0px">whois, but does not receive an answer. If deemed
lame, ARIN has an</DIV>
<DIV style="MARGIN: 0px">appropriate procedure for contacting the Org and
handling the issue as</DIV>
<DIV style="MARGIN: 0px">per "<A
href="http://www.arin.net">http://www.arin.net</A>/
reference/lame_delegations.html".</DIV>
<DIV style="MIN-HEIGHT: 14px; MARGIN: 0px"><BR></DIV>
<DIV style="MARGIN: 0px">Unfortunately, the policy does not cover the
situation of a so-called</DIV>
<DIV style="MARGIN: 0px">partially lame delegation. That is, some of the
in-addr.arpa zones</DIV>
<DIV style="MARGIN: 0px">belonging to the network registration return a
valid SOA upon testing,</DIV>
<DIV style="MARGIN: 0px">and some do not. Even if only one /24
in-addr.arpa reverse tests comes</DIV>
<DIV style="MARGIN: 0px">back as lame, it is my opinion that this still
taints the reputation of</DIV>
<DIV style="MARGIN: 0px">entire network registration. IPs belonging to
that lame in-addr.arpa</DIV>
<DIV style="MARGIN: 0px">zone will cause query timeouts to 3rd party dns
resolvers, both public</DIV>
<DIV style="MARGIN: 0px">and private. These excessive timeouts in my
opinion can harm the overall</DIV>
<DIV style="MARGIN: 0px">well-being of reverse dns functionality
throughout the internet. The</DIV>
<DIV style="MARGIN: 0px">only way to prevent such harm is for ARIN to not
delegate reverse</DIV>
<DIV style="MARGIN: 0px">authority to the so-called partially lame dns
server as registered in</DIV>
<DIV style="MARGIN: 0px">whois. That is the purpose of this policy
proposal, to consider partial</DIV>
<DIV style="MARGIN: 0px">lameness with the same prejudice as traditionally
defined lameness.</DIV>
<DIV style="MARGIN: 0px">Org's who are partially lame should be contacted
by ARIN and lame</DIV>
<DIV style="MARGIN: 0px">in-addr.arpa zones should be resolved as the
procedures per</DIV>
<DIV style="MARGIN: 0px">"<A
href="http://www.arin.net/reference/">http://www.arin.net/reference/</A>
