[Pdns-users] Question about Multiple CNAMES

I can accomplish my goals this way.. This is how I have done it in the
past.. I don't mind having to change my setup if this one just won't
work, or is fundamentally flawed. .. This environment, as you may be
able to tell, is a development environment,.. I was trying to keep the
references to specific IP addresses limited to a bare few number of
records.. This would allow me to modify the domain far easier and
simpler than having many, many A records..
This one small example is not the only place where I reference these
particular machines/IP's in this fashion..
So, baring the "right way" to do this, and personal taste.. Is PDNS's
response to the current configuration correct or "close but not quite" ?

I do not think it is valid to have several CNAMEs. I may be wrong, but
I've never seen it tried.
The classical way is to have
relay00.dev.domain.net IN A 10.0.0.1
relay01.dev.domain.net IN A 10.0.0.2
relay.dev.domain.net IN A 10.0.0.1
relay.dev.domain.net IN A 10.0.0.2
(and the corresponding
126.96.36.199.in-addr.arpa IN PTR relay00.dev.domain.net.
188.8.131.52.in-addr.arpa IN PTR relay01.dev.domain.net.
You will not have any problems with that.
