    Hello tej,

    I'm unsure as to how you would do this in Java but there are plenty of websites online that can pinpoint a computers location via the IP address.

    These look really good:

    Wrong, the IP redirects you to the provider, not the computer/network itself..

    i think XD

    Hmm... If that is the case, how come you can connect to your computer remotely using the IP address?

    Sites that try to pinpoint the computers location via the IP normally locates the ISP location rather than the exact location of the PC.

    Yeah ur rite admin.
    But have dis.This is a small test program for the IPv6 reverse lookup functionality. IPv4 reverse lookup test:

    # java lookupAndReturn mocha.cs.ucl.ac.uk
    IPv6 reverse lookup test
    # java lookupAndReturn -6 mocha.cs.ucl.ac.uk
    Successful output on IPv6 reverse lookup test:
    The initial hostname is: mocha.cs.ucl.ac.uk
    The IP address is: 2001:630:13:101:2e0:18ff:fe34:150b
    The reverse lookup hostname is: mocha.cs.ucl.ac.uk

    Source Code:

    /* This is a test program -written by Sheng JIANG - UCL
    Febuary 2004
    This program read the hostname from the command line as argument.
    Then translate the IP address into hostname and display on the screen.
    Then using that IP address for reverse lookup and display return hostname.
    The success result will output hostname, rather than IP address.
    */
    import java.net.*;
    public class lookupAndReturn{
    public static void main (String[] args) {
    try{
    String cacheAddress="";
    String cacheHostname="";
    InetAddress cacheInetAddress;
    String usageMsg =
    "Usage: displayHostnames [options]\n" +

    "\t --help\t\t\t display this message - same with -h\n"+
    "\t -4\t\t\t lookup IPv4address\n" +
    "\t -6\t\t\t lookup into IPv6address\n" +
    "\t by default IPv4 address of the given hostname will be lookup\n";
    for (int i=0; i<args.length;i++) {
    if(args[i].equals("-h")) {
    System.err.println(usageMsg);
    return;
    } else if(args[i].equalsIgnoreCase("-help")) {
    System.err.println(usageMsg);
    return;
    } else if(args[i].equals("-4")) {

    cacheInetAddress = InetAddress.getByName (cacheAddress);
    System.out.println("\tThe reverse lookup hostname is:\t"+cacheInetAddress.getHostName());

    But isn't the IP address taken from the proxy (if any)? They could very well be using a proxy service, and all you'd get is the proxy's IP.

    If they are using a proxy then yes you would get the proxys IP. Basically making it impossible to trace them with these simple methods.
