Is it possible to locate an IP address from yahoo mail?

Question

I recently booted someone from our Yahoo group and believe the individual is trying to get back into our group using a new Yahoo e-mail address. Is it possible to check the IP addresses to see if any of them match the member's who was booted? Please help because not allowing membership to our group is not fair for ligitimate people. :(

Answer 1

first, some IP address refresh or change. for instance, I can change my IP address at will so it may never be the same and your efforts may never confirm anything.

second, upon approving members, there is no way to view IP addresses

third, in order to locate the IP, the member has to post. you can view this while on the group or in your own mail. while one thr group, click on the post to read it. to the right, click Show Message Option- then click View Source- sometimes it's the 3rd, 4th or 5th line down from the top sometimes the 8th- "Received: from unknown" I have compared these lines with what comes in my e-mail which is not Yahoo provider.

the best way to protect your group from removed members coming back is restricted membership and moderated new members posts-

Answer 2

How do I find out who sent the email?

The email message itself contains some information relating to the sender's identity.

In the headers of email messages sent via Yahoo! Mail, an Internet Protocol (IP) address that corresponds to the sender's Internet service provider (ISP) is included.

At the top of a message (above the date) is a line reading either "Standard Header" or "Compact Header."

Click on this link, and a menu will drop down with an option for "Full Header."

If you select "Full Header," a new window pops up containing the full header of the message.

See it? It's got tons of computer gobbledygook, but it also has some information you can use.

You should be able to find a line that contains an 8 to 12 digit number, separated by periods.

It might look something like this:

Received: from [123.456.78.91] by . . .

The "123.456.78.91" represents the unique IP address of the sender's ISP. Once you identify the IP address, you can run a "whois" search to determine which ISP provides this person with Internet access.

If there's more than one Received: line, read them from top to bottom (the topmost is the most recent.)

There are several utilities available on the web to run a whois search. Here's one web site that can help you to determine which service provider is responsible for the IP address:
