Well Anshul, IP address and Email id have no relation.
Companies and individuals have Email addresses.

Let me explain you what is an IP address to clear your doubts

Every machine on the Internet has a unique identifying number, called an IP Address. A typical IP address looks like this:

* 216.27.61.137

To make it easier for us humans to remember, IP addresses are normally expressed in decimal format as a "dotted decimal number" like the one above. But computers communicate in binary form. Look at the same IP address in binary:

* 11011000.00011011.00111101.100 01001

As per my knowledge every email comes with a “Header” which is one part of an e-mail structure; call it DNA of the mail. It carries the basic fundamental information such as from whom the email comes, to whom it is addressed, date/time it was sent and the subject of the email. It is similar to an electronic postSeptemberk. Moreover, it also carries other detailed information which we usually don’t see.

This basic information comes in all brief/basic headers that most email programs automatically shows. This detail technical information can be viewed in a full header. All email programs can be set to show only brief header or full header and it is up to the users to set the program whether to view only “brief header” or “full header”.

Full header carries the information of the mail server’s name that the email passed through on its way to the recipient, and sender's IP address and even the name of the email program and its version used.

Knowledge of this information is essential for analysis and investigation purposes on cases involving email abuse, spamming, harassment, forgeries and mail-bombing. It is worth mentioning, understanding of this tool would definitely help people to counter these attacks, and save themselves from unwarranted consequences. Well, this information could not be found in a brief header.

well;
About the importance of Email, it is in everyone's knowledge the role it plays in our daily life. Imagine a world where there is no tool like Email. It would be horrifying and painstaking job to communicate what we do, presently with a simple click.

We all understand the utility factor attached to the Email. It is one of the fastest, reliable and personalized modes of communication. But it has been found very few understand the nuts and bolts of this communication. We merely compose, or attached what we want to communicate and send it. That's what it has been found.

At this time when Email is progressively used for business and for many purposes, not to mention it is being used for phishing and other malicious intentions. It is of utmost priority to understand the other "messages" besides what has been sent or received by you.

Whenever you get online your computer is assigned an IP address. IP address is the Internet Protocol (IP) address given to every computer connected to the Internet. An IP address is needed to route information much like a street address or PO box is needed to receive regular mail. email addresses are not IP addresses. An Example of an IP address is: 68.34.182.112

The Trace IP address service helps you search location of any IP address. It traces the City, State, Country, longitude & latitude of where the computer with that particular IP address is located and also Includes name and address of the owner of IP address. The Address for email, IP or email name searches for the physical street location of the user. Trace IP addresses of computers anywhere such as USA, Canada, UK, Australia, New Zealand, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden, Russia, Poland, Hungary, Slovenia, Hong Kong, Japan, South Korea, Thailand, Taiwan, India, Turkey, Bahrain, Dubai, Qatar, Saudi Arabia, Iraq, Kuwait, Lebanon, Jordan, Egypt, South Africa, Mexico, Brazil, Uruguay, Peru, Argentina and more...

Each computer on the Internet has a unique numeric address similar to a phone number. This address is usually assigned to the user's Internet service provider, a university or a company. A database matches such assignments to the location the network has registered. But IP addresses can all be registered to one office of the internet service provider or company even though they may have branch offices worldwide. An ISP like America Online may route its customers' traffic through a single gateway, making AOL users in Kansas appear to come from Virginia. Therefore the IP database needs to be refined, tracing data packets as they pass through traffic nodes known as routers and narrowing the actual location of each IP address. It requires detailed analysis of how do various carriers work, how they set up their network, how carriers differ from each other. This data is mapped to specific blocks of geographic areas and physical addresses. Zip codes and census data are mapped to these geographic blocks to create demographic profiles. In addition to utilizing various search techniques, searching of any available databases enables researchers to search the geographic location of a computer through its IP Address. In addition the location of IP addresses is also verified through an extensive database of the geographic mapping of IP addresses. This mapping of IP addresses to their geographic locations is updated frequently by IP information submitted from various strategic geographic locations, using many different Internet Service providers. This allows the database to create current mapping of IP addresses to their geographic locations. This database can also map location names (street, city, state, country) or US zip codes to latitude/longitude values. This information is verified through other IP address information sources. Every time anyone connects to the internet they are leaving their IP fingerprint and ISP domain name and other bits of information behind. The hops data packets make between IP's and the time required for the hops also helps in creating a map of locations. Often times this could reveal what city and state that person lives in. Many search engines archive a whole copy of the internet at regular intervals. Often times other people, pages or sites mention or list bits and pieces of information. Every activity on the internet leaves bits and pieces of information lingering around. Deducing and analyzing the bits and pieces create leads. Computer related searches estimate results by analyzing patterns, statistical probability, demographics and any other observations available. In some instances IP address mapping could provide time intelligence pertaining to when the computer was connected to the internet. In other words it can help fi

I don't think it's possible to find the e-mail id of given IP address. But the reverse is possible. i.e. to find the IP address of an mail id. You can just watch the IP address in the mail header itself. For example, In Yahoo, click "Full headers" on the upper right hand corner while you see the message. In Gmail, click down arrow mark next to 'Reply' in top of the message and from the drop down, click 'Show Original'. Once you find the IP address, you can track it by using:

http://aruljohn.com/track .pl

You'll be provided with Host name, ISP details and Country. You can contact the ISP to inquire the details about the IP address you received the mail from.
