how do i find any website ip is dedicated or shared?

[pratapsingh]

can any-one tell me how to find this information.

and when we do reverse lookup query for any ip what are the actual technical things takes place or come to the picture? How this query processed to the end and from where it gets its final answer. Where do we need to keep our zone entry for reverse lookup in the nameserver or data center's nameservers.
i want to know that this ip is dedicated or shared and on which nameserver it has record for revers lookup and where it is located.

I get a dynamic in place of static and mine is dynamic, so it means the reverse DNS is useful for finding whether IP is static or dynamic

[pratapsingh]

that is for ur router or local dns they may be static or dynamic .. it depends on ISP provider .. to make it static or dyanamic...

Static IP connection plans are quite costly. Mostly they provide dynamic ips

No .. u did nt get my point ... i got that how to find out an ip is dedicate dor not .. if u have a server access then go to the httpd.conf file check the virtual host entry ... from there u will get to know that that ip is dedicated or not and after that do reverse lookup if the host name is resolved and if typing that ip on url u r able to access the website of that ip and it si pointing to the resolv host name this means its an dedicated ip.

But i want to know that where is the ns record for reverse lookup because i have checked a ns record for my website and PTR entry was not in that so i want to know that where is the PTR entry for my domain .
