Title: Re: [IMail Forum] PTR record for web
servers
Seems odd that we didn't have to do anything for the mail server and we
have it. We do get our bandwidth from Qwest and ESi owns the building
we're in.

In MS DNS we appear to have a pointer
record for our web servers but when I do a lookup on them it says that
we don't. Obviously we're missing something here and would appreciate
your help.
Thanks,

Go to www.arin.net and enter the IP address of your webserver.
Even though your company does the forward lookup for the domain, the
PTR dns entry maybe controlled / listed as being controlled by a
different company.
For example:
PINE.MATROSITY.COM has a forward look up of:
pine.matrosity.com.
86400
IN
A
65.112.155.254
The "reverse lookup" ((PTR entries? You have two
PTRs))
254.155.112.65.in-addr.arpa.
3599
IN
PTR
mail.matrosityhosting.com.
254.155.112.65.in-addr.arpa.
3599
IN
PTR
mail.matrosity.com.
According to ARIN the IP address 65.112.155.254 is owned by
Qwest
and leasted to E.S.I.S Services. You may need to make sure
that the PTR look up for your webserver is "delegated" to
your Name Server.
