Mapping and Tracing search engines IP addresses is useful for several different reasons. The reason of tracing might be like you may want to see when and which pages of your web site were spidered by search engines robots. You may feel like to ban some harmful bots and let others in. You might want to see which bots are following your robots.txt files.

However keeping track on the various IP addresses belonging to search engine spiders is bit difficult because it requires lot of time. You may need to verify that the IP addresses are indeed genuine and they belong to search engines? The lists you may get might be correct but there is no guarantee that they include all of the IP addresses of all search engines and so on there is no certainty that all of the IP addresses contained in the lists belong to search engines because they are sometimes reassigned or abandoned.

IP tracking also help you to track down the owners of IP addresses or figure out where spam is coming from…but you should know how to track down spammers IP address. .

The IP addresses are enclosed in a flat file database format, which is confined under intellectual property law and treaties, however the IP addresses themselves are public domain and not protected. When you receive an email, the IP Address of the originating computer will contain within the email, in a section of it, which is known as the “headers”. Most of the headers are concealed in most email applications though you can only see the sender’s name, email address, the date and time sent and the subject. However most email applications will allow you to view the complete headers. Check your email application’s help documentation to determine how to do it in your case.

In most cases, you will see a number of lines in the headers that start with the word “Received” followed by a colon (“:”). These are what you might be interested in for looking for. Whenever an email moves from the sender to you, it passes through various servers. Each server adds its own line in the “Received” headers. The newer lines are at the top, so the last “Received” line is that of the original sender.
