URL-- How do you determine what your url is? I have email at yahoo, aol, & another, does each have a diff. url

Which URL are you asking about? If you are running a Windows PC, you can open a command window and type the command "ipconfig" (no quotes). The resulting display will give you a series of four numbers, separated by periods. This is the IP (Internet Protocol) address of YOUR machine. URLs generally are of the form www.name.extension (such as www.msn.com or www.bcps.org, etc.). These are mnemonics that translate to an IP address.

Antique network commands you can play with in a command window are "ping" and "tracert". If you Ping a specific URL, the IP address is displayed back to you. URLs are generally easier to remember than IP addresses, unless you're a hardware/network person.

To answer at a higher level, each internet location has its own address, unless one location is a pseudonym for another address. Then either name gets you to the same IP address. Yahoo owns its location, servers, etc. as does Microsoft and AOL and Google. If they had the same address, then they would pretty much need to be in the same physical location. Just like a street address. (How would you be able to reach the Empire State Building if it shared it's address with Times Square?)

A URL (uniform resource locator) is an internet address. It can be a web page like http://www.yahoo.com/somepage or it might be an e-mail address like mailto:myname@yahoo.com

So to answer your question, yes each of your different e-mail accounts does have a different URL.
