Which IP address comes up?
The IP address of the computer you are logged in on or the computer that the Id, email, etc was made on?
Update:I might not have been clear with my question. If someone who knows how to get ip addresses from Yahoo id's, email adresses etc. finds my IP addy, will my ip address come up or the ip address of the computer the id was originally made on?

There are two types of IPs. Private and Public.
Each computer gets assigned its own unique private IP address from your ISP. When you then connect through the ISP to the internet, you get assigned a Public address that is used on the internet (public). The IP address of your PC still remains the same private one. Only the ISP maps yours to a Public IP.
When ever you do something on the net, your public ip address get associated with that activity. Its like you're leaving fingerprints.
When you send a mail, it doesn't matter from what ID it is sent , where the ID was created or from which mail client, only the private IP of the physical computer from where this takes place will be sent to the ISP from where it's mapped to a Public IP and thus it is traceble.
If you need to know from where an Email ID was created, the Mail client i.e. Yahoo! would be able to establish from their records the IP of the creator.

Only the info of the PC from where the mail was sent will be associated. To find out from where the mail ID was created you would probably need a subpoena to get this info from Yahoo or Google or who ever the mail client is.
Your computer generally accepts the IP it's given when it connects to a network, sometimes if the computer is set up to demand its own specific IP it's on the instructions from your computer, but it's still handed out by the network manager - on the Internet that's your ISP, when you're using a wireless network hotspot that's the wireless access point. On a side note - in that case it's the wireless access point's ISP that gives the access point its IP.
it depends on what you are doing. If you are tracking an email, then it will show the IP of the person who made the email. If you are using a function to simply display an IP, then it will most likely be the PC you are using.
Depends on what your referring to. If you mean....if you send an email. Both IP's can be tracked if they want to trace them. Any computer you are on can be traced along with any of the sites/emails/etc. If you create the account they know where it was created and if you send an email from a different PC they can still trace that PC.
it is embedded in the header of the first packet to be sent over the network/internet. it would be the IP of the computer that sent the file in the first place. (the computer you are SENDING the file from. a transfer before send (via a flash drive, for instance) won't show up.
When something is sent from your computer, your IP address is attached, yes.
