I have not used that DNS checker in a very long time.
But here is a great one that does all that but it will throw a warning about an A
record having more then one hostname to an IP
http://www.uniplus.ch/tools/dns_check_set-en.html IMO the best DNS test oh yeah and it
is totally free

that's warning, not a fatal, and often such "strange" serial numbers
are not what the DNS admin wants them to be. Any number is
acceptable, up to a limiting size.

I haven't seen that error or warning from DNS expert and, as you say,
it's perfectly legal anyway. I recommend that here all the time for
Imail ip to have mail, smtp, pop, webmail hostnames.
certainly a zone checker is not going to check that you've used the
same ip in two different zones. What program do have the complains?
