Reverse DNS

Applications IP Networking
1

Hello, I'm trying to get reverse dns to point to my domain on network but I'm failing. I am using bind dns with port 53 enabled and my ISP is mediacom. Currently my reverse dns is *.client.mchsi.com and I would like to make it example.com basically.

My bind configuration

I have 2 records, one for my private ip and one for my public just incase it needs to be my private one. Here is my private one, the public one is the same thing but with my IP in place.

$ttl 38400
62.168.192.in-addr.arpa.	IN	SOA	ns1.example.com. support.example.com. (
			1271713563
			10800
			3600
			604800
			38400 )
62.168.192.in-addr.arpa.	IN	NS	ns1.example.com.
62.168.192.in-addr.arpa.	IN	NS	ns2.example.com.
12.62.168.192.in-addr.arpa.	IN	PTR	example.com.

I have tested both ways through dig on terminal and they work fine, but when I test using my dns providers dns server, it returns the same *.client.mchsi.com domain and not the one I specified. I waited 3 days to test again and I get the same result. The time to live returned by dig is 24 hours just to note. Any help?

Thanks,
Mr. Gecko

Reverse DNS is done by your ISP unless it has been delegated to you by them. :wink:

That's some what sad, I don't really like communicating with my ISP as I have no idea what they'll say about me running a server on my network. I really think that we should not have to worry about this as the internet should be free and I should be allowed to share my content I make via my server.

OK, there's a few logical errors here

  • The internet is free. However, each provider may decide on their own what kind of traffic they allow to be transported on their networks, as they can be held responsible if its illegal. Also, if everyone had the possibility to run a server at home just like that, who would rent space in their data centers?
  • Your providers DNS can only do reverse lookups for the entries it knows about. And that would require you to be in charge of the authority name server for the example.com domain.
  • Even if you could do the reverse lookup as wanted, it still wouldn't work outside your own network, as you're using IPs from a private block, which wouldn't be routed beyond your provider, at best.

I don't want to get into a flame war about internet freedom of content that we own. But I still think the ISP shouldn't be allowed to block content, for an example if I was to watch hulu, ISP shouldn't be allowed to slow down the connection or block hulu. I should get consistent access to anything and the ability to do what I want with my content I made by opening ports to my webserver. I am not going to be come a web host or anything, it's just for some of my stuff I made and I am sharing with people. That's it for me, I'm not changing my mind, please do not add to that or say I'm wrong as this would go into a flame war.

And I understand that my ISP controls the reverse lookup from macwunder.

Thanks for your help,
