Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Only Yahoo's servers know that, and they're not going to tell you. I can't think of any *legitimate* reason why you would need to know this.
If you can connect directly to that person using yahoo messenger, like to send them a file, you can go to the command prompt and type netstat -a to get a list of all'll be able to see the users ip address in that list.

hope this helps.

according to  DVation191 , but when  you chat whit severral person, you can't know exactly who you want to acheive IP address
simply chatting with somebody, you cannot see their ip using that command. only if you connect directly to them will you be able to see unless you are connected to more than one person directly, it wont work.
You would have to ask them to tell you what their IP address is--Yahoo messenger can not give you that information. If they send you email you can see what their IP is, but remember that in many cases IP addresses are changed so what a person is using today or this hour may be someone elses tomorrow.

If you explain what you are trying to do, one of us can possibly help you determine the information you need to know.
