The major problem here is software packages that can't deal with the
possibility of setups like this:
www.mycorp.com CNAME round-robin.server.mycorp.com
round-robin.server.mycorp.com A 198.168.1,1
A 198.168.2.1
A 198.168.3.1
Yes, major software vendors are still managing to get this Totally Wrong.
And when somebody at the VP level says something WILL be deployed in time
for another non-negotiable deadline (for instance, 25K students returning
to campus), you end up with some ugly ad-crockery with PTRs ;)
Yes, we'll fix the PTRs. Soon as we get a patch from the vendor. 'Nuff
said. ;)
