Forward DNS Not working Correctly....Need HELP.

[redhat70]

Hi,

Forward DNS is not pointing to the correct IP, Where as Reverse DNS pointing to the correct IP.

How to change the Forward DNS to point to correct IP:89.204.217.51 ?


Forward DNS:
===============
# nslookup mail1.seftec.ie
Server: dns1.o2.ie
Address: 62.40.32.33

Non-authoritative answer:
Name: mail1.seftec.ie
Address: 89.204.215.233

Reverse DNS :
===========

# nslookup 89.204.217.51
Server: dns1.o2.ie
Address: 62.40.32.33

Name: mail1.seftec.ie
Address: 89.204.217.51


Regards,
Appu.

I get very different results from you:

# nslookup mail1.seftec.ie
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
Name: mail1.seftec.ie
Address: 89.204.217.51

# nslookup 89.204.217.51
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
51.217.204.89.in-addr.arpa name = mail1.seftec.ie.

Authoritative answers can be found from:
217.204.89.in-addr.arpa nameserver = dns2.o2.ie.
217.204.89.in-addr.arpa nameserver = dns1.o2.ie.
dns1.o2.ie internet address = 62.40.32.33
dns2.o2.ie internet address = 62.40.32.34


may be you have some old data in the NS you use
reboot your NS or use a different one if your results come from your ISP-NS
