Re: repeating records

["D. J. Bernstein" <djb@cr.yp.to>]

Okay. Andrews has specifically endorsed the three statements

   * ``DNS servers SHOULD NOT use LDAP'' and
   * ``DNS servers SHOULD NOT use EDNS0'' and
   * ``DNS servers SHOULD NOT use BIND 8's AXFR glue strategy''

because he claims that every DNS server implementor must understand and
carefully weigh the implications (specifically, some minor efficiency
issues) before doing any of these things.

Is this the same Andrews who has been telling everybody to use EDNS0?
``SHOULD NOT use EDNS0,'' but please use it anyway? Does he understand
how stupid he's making himself sound here?

Andrews tries to defend his silly AXFR position by saying that ``zones
are getting MUCH bigger'' and by pointing to DNSSEC. But bigger zones
and DNSSEC make BIND 8's AXFR glue strategy even _less_ of an issue! The
djbdns/BIND 9 strategy saves space _for repeated delegations_, not for
miscellaneous records.

In short, Andrews is making the ludicrous demand that every implementor
worry about the .com zone. This is a transparent attempt to hold back
progress in DNS server software.
