ThumbnailAn IP (Internet Protocol) address is as unique to a computer as a fingerprint is to us. An IP address How The Internet Works [Technology Explained] How The Internet Works [Technology Explained] Read More enables one networked device to talk to the next. The downside of this inter-connectedness is that a logical location provided by the IP address is an open arms invitation to spammers and hackers. The art of war necessitates the importance of knowing who your ‘attacker’ is. Being able to trace an IP address to a PC is a direct way to remove the cloak of anonymity from a computer communicating with your own.

An IP address is a series of digits separated by dotted decimals and represented from to Currently we are following the Internet Protocol Version 4 (IPv4), although the successor “˜version 6′ has been standardized.

A good hacker will take steps to prevent his IP from being revealed. A spammer might hide behind a proxy server. It is also important to remember that locating an IP address using online tools does not reveal the physical address of the guy on the computer. The basic tools merely tell us the location of the ISP providing the connection by using publicly available information. To go beyond that and actually nail down the guy sending you the dirty emails would require the law to be in the loop.

Stefan’s post on How to Trace Your Emails Back to the Source How To Trace Your Emails Back To The Source How To Trace Your Emails Back To The Source Read More is required reading for a very useful application of IP address tracking. An interesting comment has been made by a reader who says that he uses IP address tracing to ‘find out the origin of potential customers who send e-mails and make inquiries through his company’s website’.

In the lines that follow, I am taking Stefan’s post as a stepping stone and extending it by listing sites which serve as tools to trace an IP address to a PC. Any one should be enough but is there any harm in bookmarking a few more?

    Part 2: How to Find Your Own IP Address

The 7 online tools covered not only give you the location of a foreign IP address but yours too as soon as you hit their landing page. There are many online services which decipher your IP address in a flash. Here are a few from the swarm –

      ip trace tools

    (Please note that your IP address may be static or dynamic depending on how the DHCP server that’s assigns the IPs is configured.)

    The ISP service provider knows exactly where we are located. With the tools mentioned here, at best we can find the approximate area (even though a city is a large area!). It’s still useful”¦and sometimes it’s fun too.

    Have you ever had to use IP tracking? Tell us why and how”¦

      I used IP address tracking to find a long lost girlfriend. It was fun for me, but I guess I somehow scared her off, when I was able to accurately pinpoint her locale while being halfway across the globe.

      In your graphic, you are circling the MAC address, not the IP address. The MAC address can be used to figure what kind of computer you are talking to (the first 4 octets uniquely identify the company that made the network card...) Unfortunately, MAC address info is generally not routed beyond the local LAN.

      Also, ipconfig is useless for what you've described in the rest of the article for most people. Most people connect to the Internet through a router, which assigns a private IP address (via DHCP). The router uses a service called "NAT" to forward Internet packets to your computer. The outside world actually sees the IP address assigned to your router. The router IP address is assigned to it by the ISP. That is the address that these program use to figure out where you live.

      quick correction...

      IP Addresses go from to (not There are 256 possibilities for each part of the address, 0 being the first.

      Another way to think about it is each part is actually 1 byte. The range therefore is (in hex) 00 to FF(255).

      I've used for a year now. Works great for me. I trace IP addresses logged by our company router who are flagged for DoS attacks and such. Interesting that they all come from Europe and Asia. Just sayin. Also it seem that all the IP's I trace end up being companies and not individuals.

        I like network-tools too - been using it for years. One thing to remember is that most attacks take advantage of a misconfigured company server that leaves it vulnerable to a trojan. The hacker hijacks the server and starts sending spam or conducting DoS attacks, etc. Most of the nasty spam I traced years ago went to small companies, who I contacted. They apologized profusely and were always very embarrassed that their server had been hijacked by a hacker.

        Great article Saikat - fantastic resources!
