ip address from an email address

I mean that the ONLY server you know about is "aol.com" and "freeserve.com"

You CANNOT get an IP for a specific e-mail address unless the server tells you the user's IP. In the case of AOL this WOULD (technically) be possible, but I don't think they'd do it because many users consider that a lack of security / privacy (after all, you can start all kinds of attacks if you know someone's IP).

If you have an e-mail-address like MisterX@hotmail.com or yahoo.com or whatever, there's no way they can even know the user's IP-address...

Just think about it and believe it...
I doubt .
Which IP-address do you want to get? The user's? (I mean the guy who own the e-mail address)

That is not possible. At most, you can get the IP for the e-mail server that's responsible for an address.

If somebody has surprised you by knowing your IP from an e-mail: Many many times, you can see the sender's IP-address from an e-mail.
I mean: an actual e-mail which you sent to somebody. The IP "can" be contained in the header.

Please let us know what you want and how you know that it is possible :-))

i want to get the ip from an email address i put in eg;
input me@me.me output 214.567.56.865 so i can tell if my friends are online i know it can be done Because msn messenger does it and i rember seeing an artical about it some where !
I don't know how MSN-messenger works but it MAY have some access to server-side data (i.e. information provided by the Internet provider (MSN?))

Here's a VERY simple reason why this CANNOT work in general and for arbitrary e-mail adresses:

I have just ONE e-mail address, but a different IP every day. Now if you say the e-mail provider should know: No way, they don't even know if I'm online.

Stuff like that can only work for e-mail addresses maintained by the internet providers, but never for stuff like POP3-servers or webmail...

i know now how to instant messaging and the online detection thing works your computer uses a function and a server called ICQ or 'I Seek You' look at this page for more info

  The way the messenger clients do it is that they check the messenger server to determine
if the user is logged in and reads the logged-in IP address from the messenger server's
database. They only use the email address to determine the user.
