Tracking or Locating a Server online?

Is there any way you can locate the Server of a Webpage? I am wondering this in case I want make a webpage on the same server or something like that.

  • You can often determine the owner or operator of a web site by using the whois command or a whois server.

    whois example.com
    

    Or try this Verisign whois server (one of many).

  • Your question is not very clear. If you want to lookup IPs you can use also use tools such as MaxMind's geographic IP location database or ARIN's whois lookup.

  • You are looking for a way to know where the server is actually hosted (the actual hosting provider).

    You can try this (using bash):

    whois "$(dig +short www.codealpha.net | grep -m1 '^[0-9]')"
    

    In this case, this returns

    OrgName:    Linode
    [...]
    

    This can be tweaked and improved.

    Here's a way to do it in a bash function:

    #!/bin/bash
    
    function whathost()
    {
      whois "$(dig +short "$1" | grep -m1 '^[0-9]')"
    }
    
    whathost linux.com
    

    Notes:

    Note that some results will probably not meaningful, this is because they own the IP address and host their own server.
