I am having difficulty configuring reverse
DNS. This has been a problem for over a year between my
server(s) and my ISP, AT&T. Specifically, I cannot eMail
to any recipient that requires rDNS verification, e.g.,
SBCglobal.net, Comcast.net, or AOL. Very frustrating.
Two examples of dig:
# dig -t mx alpha.archaxis.net
ANSWER: 0, AUTHORITY: 1,
Why does this first example, digging the FQDN of
alpha.archaxis.net reports one authority but no answers?
# dig -t mx archaxis.net
ANSWER: 2, AUTHORITY: 0,
. . .yet this second example. digging the FQDN of archaxis.net
reports no authority but 2 answers?
(The) ;; ANSWER SECTION: (of both examples) reports:
archaxis.net. 10800 IN MX 30
bravo.archaxis.net.
archaxis.net. 10800 IN MX 20
alpha.archaxis.net.
In both cases, the reported server is an AT&T server ;;
SERVER: 68.94.157.9#53
. . .why shouldn’t this “point” to my server, 162.202.233.81 and
not AT&T’s?
I have coded my BIND 9 in-addr.arpa zone file as follows:
$ORIGIN 233.202.162.in-addr.arpa.
$TTL 3h
@ IN SOA ns1.archaxis.net.
me.archaxis.net. (
2017012002 ;
Serial
1h ;
Refresh
1h ;
Retry
1h ;
Expire
1h ) ;
Negative cashing TTL
3600 IN NS
ns1.archaxis.net.
3600 IN NS
ns2.archaxis.net.
80 3600 IN PTR
network.archaxis.net.
81 3600 IN PTR
alpha.archaxis.net.
82 3600 IN PTR
bravo.archaxis.net.
87 3600 IN PTR
broadcast.archaxis.net.
What is wrong? Is this my problem, or with
AT&T?
