[Pdns-users] Limit on Zone Transfer Size ?

[DORDAL]

Guys-

Question about zone transfers. We setup a subdomain record for each client
we get; e.g. client1.mydomain.com, client2.mydomain.com, etc. A trusted
friend insists this will break soon because of limitations on zone
transfers; he says that AXFR requests are limited to 65535 bytes, and with
an average of maybe 30 bytes per client record, we'll hit this just after
2000 clients. Our backup DNS servers won't be able to update, clients will
be unhappy, etc.

Problem is, I can't find any mention of a 65535 byte limit. Closest I've
come is there seems to be a 65535 byte limit on TCP DNS message size, but
this doc: http://tools.ietf.org/html/draft-ietf-dnsext-axfr-clarify-00  says
the master will just transmit multiple messages.

Should I be worried?
