Hello,

I tried to do a reverse dns by using the following commands, but I couldn't get it to work.

Can you take a look at it and see if there is any mistake?

If you were allocated 207.33.15.144/28 you would name your zone file:

subnet144.15.33.207.in-addr.arpa


If you were allocated 207.33.15.144/28, you would use the following commands

nslookup -type=CNAME 144.15.33.207.in-addr.arpa. ns1.yourname.com.

nslookup -type=NS subnet144.15.33.207.in-addr.arpa. ns1.yourname.com.


configuring your name servers for a full class C and not a subnet
range.

I want to be able to configure the name servers for a subnet range, not for a full class c.


:cool:

Come on,

Someone has to know how to do it. :cool:

i hate that
when u post and u wait hrs and no one helps
:)

For a true full functional (outside the local environment) reverse DNS don't you have to have full control of the IP? If you just want local resolves (ie. on the machine) I belive you can change this in /etc/sysconfig/network or similar.

For example WebHostingTalk.com's IP is 209.249.55.203 and our reverse DNS (as in traceroutes etc..) is panther.webhostingtalk.com . Running this IP through Arin's IP Whois (http://www.arin.net/cgi-bin/whois.pl) shows the inverse mapping system for this IP is provide by NS.ABOVE.NET. I forwarded my request for reverse DNS to Voxel who in turn I believe forwarded the request to Above.Net. DNS and reverse DNS are often handled by different servers as in our example EasyDNS provide our standard DNS (domain to IP mapping).

I may be way off on this one, but since no one else has replied I thought I might as well. Good luck

extra: I ran the IP 207.33.15.144 through arin.net and it shows Verio provide the inverse mapping.

You are close on your thinking. Did you provider delegate the in-arpa's to you?

They told me that they did everything on their side.

I did a traceroute on 64.71.148.130

Output ...

3 198.32.146.21 16.334 ms mae-la.above.net [AS226] USC/Information Sciences Institute, regional network, Los Nettos

8 64.71.148.130 18.197 ms DNS error [AS6939] HE.net

I clicked on "DNS error" link to check out the DNS error.
I got this...

64.71.148.130 has no reverse DNS configured.

I just did a debugged look up of that IP and this is what is shown.

QUESTIONS:
130.148.71.64.in-addr.arpa, type = PTR, class = IN
ANSWERS:
-> 130.148.71.64.in-addr.arpa
type = CNAME, class = IN, dlen = 16
canonical name = 130.subnet128.148.71.64.in-addr.arpa
ttl = 86394 (23 hours 59 mins 54 secs)
AUTHORITY RECORDS:
-> 148.71.64.in-addr.arpa
type = SOA, class = IN, dlen = 42
ttl = 10800 (3 hours)
primary name server = 148.71.64.in-addr.arpa
responsible mail addr = staff.1000megs.com
serial = 1005991085
refresh = 10800 (3 hours)
retry = 3600 (1 hour)
expire = 604800 (7 days)
default TTL = 86400 (1 day)

Looking at that, I would say they did not deligate it to you. You should see your name server in the Answer portion of the lookup.

Hope that helps!
