My reverse zone for xxx.xxx.xxxin-addr.arpa-hosts
has reference to only one NS record
@ IN NS www.xxx.xxx.xxx.us
which is a reference to the local name server.
Can I also add references to the ISP that also keeps track of my domain
in the reverse zone in this way way
@ IN NS NS1.xxxx.net
@ IN NS NS2.xxxx.net
@ IN NS NS1.yyyy.net
@ IN NS NS2.yyyy.net

The zone xxx.xxx.xxx.us-hosts
has reference to the name servers already
@ IN NS www
@ IN NS NS1.xxxx.net

etc.,etc.

I am unclear if I have to put the entries in both master files.
Thanks

Don,

As we tried to explain privately, your NS records should match the list of name servers that are authoritative for your zone, which in turn should match the list of NS records in the parent zone.

As I recall, there were two different ISP's or offsite servers involved, and every one of them had problems. However, without real data, we can't check for you.

Use a shell command like this to see the chain of delegation/authority:

dig xxx.xxx.xxx.in-addr.arpa soa +trace

Chris:
Thanks, I found a typo in DNS at the U or M. I understand what you are saying, but I am unable to tell those in charge of the servers as to what to do.
I will do the test tomorrow when I am at school also.
Don

Interesting response. Looks similar to what you had in the e-mail.
This is from a home computer through the ISP that I use at home (not school ISP).

So far I have not been getting many complaints on mail at school or from those sending to school accounts. So I have not made but a couple of changes.
Thanks
Don
