Can you find an ISP Address just by having the email address?

Answer 1

sorry sweetheart, but I think you mean to ask IP address instead of ISP address.

ISP = Internet Service Provider
IP address = Internet Protocol address

You can see your IP address and other details echoed back to you on many sites, e.g. www.whatsmyip.net .

Your ISP assigns IP addresses to their users as they connect to the service. Depending on how it is done, users may have a fixed IP address or may be assigned a different one every time they connect to the net, good until they disconnect. Yet other ISP's (e.g. AOL) use a method of continually changing their user's IP address at each web access.

Hope this helps!

Answer 2

If you mean IP address, an email address doesn't have an IP address. The SNMP (Simple Network Mail Protocol) has a mechanism for finding the IP address of the domain's mail server. Your computer's nameserver queries the authoritative nameserver for the domain and asks it for the mail server IP address. Your mail client then communicates directly with the computer at that IP address. But that address would be the same for all users at that domain. Your mail client probably doesn't have a way for you to ask what that mail server IP address is.
