Dear All,
I want to know about DNS server queries, and what are all information we can get it from a DNS server. Actually I am intrested in finding the region of given IP address.

What I need to do now is to identify the given IP address is from which country.
For This I need to determine the IP ranges allotted be country as well as the domain extensions (say .co.in for India). Then I will keep this information in a table.
So that against a given IP address I can search the table, and can identify it country and region.

So now, I want to know from where I can get this information about IP address ranges and domain extenstion, to store in table. Do you have any idea.

Waiting for some +ve responses.

Hey Rajat, this answers your question in part

Here is the IP-to-Country database.

Thanks puru,
Really its the exact information what I needed. Thanks again.

Hi Puru,
One another way is also possible to get the location of a given IP address. We can query the "whois server" and get the information in its response.
Do you know the query format and how to parse the response at client side to get the relevent information.

are you looking for

whois <ip adress> @whois.<area managers>.net

The area managers can be arin or ripe or apnic or ...

ya exactly........but how can I get this information at IP. I mean can you tell me the query packet format and response format, as well as how to parse the received response(Usage of whois protocol).

whois.arin.net is kind enough to point you to the appropriate area manager in case it does not own the IP range.

Try
whois 64.179.4.147 @whois.arin.net

Similarly, try to whois your WAN IP at the arin whois servers.

ya that is okay....actually I want to implement the same kind of service, which can be able to provide the location of a given IP address. So for that I need to query the whois server, thats why I want to know abut the query and response packet structures etc.

hi,
I made some queries to the whois servers, but whatever response I got is in human readable text formate. More over the response format of each server is of different form. So I was not able to parse it and get the relevent information.

I searched the net, that if we can get the response in proper xml format. So that I can easily parse it. I got one mail in a message archive, in that it was stated that if we sand whois query in XML format then will get the response in XML format only. Other wise simple text response will be returned.

Does any body know that how we can query the whois srevr in xml format??
