A little while ago, George Michaelson sent a summary of his proposal to
clean up lame delegations in the bits of the in-addr.arpa domain that
are delegated to APNIC. George also mentioned some other efforts which
are trying to define similar policy, including work done by LACNIC,
ARIN, RIPE and JPNIC/WIDE.
As the new chair of the APNIC DNS SIG (hello!), I have been asked to
find out what people think about a couple of key points relating to
this policy.
Before we get into exactly what everybody else's proposal is doing, and
what we might do to facilitate a consistent policy across RIRs, here
are a couple of open questions for this list:
1. When exactly should a delegation be considered lame?
- when all/some of the delegated nameservers give no response to
queries?
- when some/some of the delegated nameservers give non-authoritative
or otherwise unreasonable responses to queries?
- some other criteria?
2. When should a lame delegation be considered "lame enough" for some
action to be taken?
- how many measurements?
- exactly what query or queries?
- measured from how many places?
Opinions from the list on these two questions would be very good to
hear.
