The IESG plans to make a decision in the next few weeks, and solicits

In Section 4:
"<proto> MUST be "udp" for the current AFS protocol, which uses Rx
over UDP."
It would be better to specify what the current AFS protocol is.
"As specified in [RFC1034], DNS RRs MUST be discarded after their TTL,
and the DNS query repeated."
RFC 1034 actually says:
"The TTL describes how long a RR can be cached before it should be
discarded."
RFC 2782 refers to RFC 1035. The same reference could be used in
this I-D. I suggest changing that paragraph to:
The time-to-live (TTL) is defined in RFC 1035. The TTL describes how long
the SRV record can be cached before it should be discarded. Any information
derived from the SRV record, such as preference ranks, MUST be
discarded when the
DNS SRV RR is expired.
Quoting the last paragraph of that section:
"AFS clients MAY remember which targets are inaccessible by that
client and ignore those targets when determining which server to
contact first. Clients which do this SHOULD have a mechanism to
retry targets which were previously inaccessible and reconsider them
according to their priority and weight if they become accessible
again."
In the "TTL" paragraph, it is specified that any information derived
from the SRV record must be discarded. That would include the target.
In the example in Section 6:
"afsdb1 A 172.30.79.10
afsdb2 A 172.30.79.11
afsdb3 A 172.30.79.12"
IPv4 addresses from TEST-NET-1 (RFC 5737) can be used:
afsdb1 A 192.0.2.10
afsdb2 A 192.0.2.11
afsdb3 A 192.0.2.12
Please add an IANA Considerations section that says:
This document contains no IANA actions.
