[ppml] Is this Lame or what?

That is a good point, and I had the very same question before  
posting. So I emailed the ARIN hostmaster for a clarification.

Hostmaster confirmed what you state below:

"Only if all of zones for a given name server of a specific network  
registration are lame, is the delegation registration deemed lame"

That is valid, correct, and should stay as-is.

Here is the problem. There is an ISP with a /22 network registration  
(4 /24's). Everything is delegated to a set of DNS servers. Those DNS  
servers correctly answer SOA request for 3 out of 4 of the /24 in- 
addr.arpa's. However, that last /24 was left out, and the ISPs DNS  
server does not answer on the SOA request, even though the ISP uses  
that /24.

So the question is, what do we do? Under current ARIN policy it  
sounds like the above scenario does not deem the ISP's /22 reverse  
dns delegation lame. Its only lame if all 4 /24's were lame, but in  
this case only one is lame. So nothing is done.

Problem is, this is a problem! If any /24 in-addr.arpa is lame, even  
though other /24's in the ISP's network registration are not, the ISP  
should still be considered "partially" lame, and should still be  
contacted by ARIN to remedy the situation.

And the overriding rationale for all of this is that the one lame /24  
is causing issues (like timeouts) for other people on the internet.

Its like sending 4 kids to school. 3 have their books and homework,  
and 1 has nothing. The 1 kid with nothing will cause issues for the  
teacher and the rest of the class. Now is it as bad as sending all 4  
kids to school if all 4 had no books or homework... No. But its still  
bad, and the parents should be called in for a teachers meeting due  
to their irresponsibility!
