IP Networking

Hi all,

Need help. Is there any way to block to query all the domain names resolving on same IP. By using tools like I want to show only the domain name if I use IP it should not show any domain name.

Is this a web query block, an IP traffic block, or a DNS query block?

I think it is DNS query block. I don't what to show external work about my DNS record and A-Record assign to that IP.

If I use the tool to DNSStuff it should show blank in DNS record to secure how may domain I am using for that IP
I think it is DNS query block. I don't what to show external world about my dns record and A-Record assign to that IP

In a right world, there would be one A record and one PTR for the ip-name pair. For aggressive web hosting, many names resolve to the same IP, either by CNAME or, sadly, additional A records. Is this a need to block web access to all names that go to one IP? An IP block seems more normal. However, for a group of hosts all using the same DNS servers to reach the Internet, you can place CNAME or A records closer to them that will resolve the name to a different address. I once helped a customer set up an AOL proxy on their firewall that way. Everyone behind the firewall thought the firewall host was also some AOL host due to the misplaced A record on the firewall DNS, and the AOL port was a pass through to the real AOL servers.
