Hi all,
I have reviewed draft-ietf-dnsop-respsize-07, as I promised to do in
Prague.
2.1.5. DNS label compression allows a domain name to be instantiated
only once per DNS message, and then referenced with a two-octet
"pointer" from other locations in that same DNS message (see
[RFC1035
4.1.4]). If all nameserver names in a message share a common parent
(for example, all ending in ".ROOT-SERVERS.NET"), then more space
will
be available for incompressable data (such as nameserver addresses).
I think this should say "... allows the component labels of a domain
name to be instantiated exactly once per DNS message, and then
referenced..." This is clearer to me than the text above, although I
don't believe the original text is so confusing that this change is
absolutely necessary.
I tested the source code and it works as advertised.
As a "zone owner" (to use this document's phrase), I found this
document useful and clearly written, and support its publication in
the RFC series, with or without the small change I suggested above.
I note that the idnits tool when run against this draft produces a
small avalanche of issues, but I presume this is something to be
figured out between the authors and the RFC editor rather than by
this working group.
Joe
