Hi,
Have a freebsd server with two ip address, ipaddress1 and ipaddress2.
My second ip address when I use www.myserver.com for rev dns gives the below error.
x.x.x.x[ipaddress2] PTR record: xxxx.myserver.com. [TTL 86400s] [A=x.x.x.x [ipaddress1] *ERROR* A record does not point back to original IP.

I have three virtual servers set up on the box all with ipaddress1 and ipaddress2 but with different ns1.frist.com ns1.second.com ns1.third.com and similarly for ns2 .

Also when I run DNSreport i get
ERROR: Some of your nameservers listed at the parent nameservers did not respond. The ones that did not respond are:

ipaddress2 [that is my second ip address does not respond]



below is my records file all the virtual host are of a similar format

$ttl 3600
domainname.com. IN SOA ns1.domainname.com. admin.domainname.com. (
1112889958
3600
3600
604800
3600 )
domainname.com. IN NS ns1.domainname.com.
domainname.com. IN A x.x.x.x[ip1]
domainname.com. IN NS ns2.domainname.com.
domainname.com. IN MX 1 mail.domainname.com.
www.domainname.com. IN CNAME domainname.com.
ns1.domainname.com. IN A x.x.x.x[ip1]

ns2.domainname.com. IN A x.x.x.x[ip2]
mail.domainname.com. IN A x.x.x.x[ip1]
mail1.domainname.com. IN A x.x.x.x[ip2]
domainname.com. IN MX 1 mail1.domainname.com.
domainname.com. IN A x.x.x.x[ip2]
domainname.com. IN TXT "v=spf1 a mx ~all"
xxxx.serverid.com IN TXT "v=spf1 a -all"
mail.domainname.com. IN TXT "v=spf1 a -all"
mail1.domainname.com. IN TXT "v=spf1 a -all"
