Hi (this is not specifically Mac related, sorry about that) I got two emails from someone using a yahoo email acount. In one that person is saying that she is in Montreal, Canada, in the second, that she is in Hamilton, Canada using "a friends computer". In both cases though, when I go to the email source header information, the IP adress, that yahoo received the message from is identical. It says: Received: from [126.96.36.199] by web41115.mail.yahoo.com via HTTP. Is she lying??? This is a sympatico.ca IP address, appearently a canadian internet provider. As far as I know, she doesnt have a laptop. Is there ANY possibility that using two different computers in two different locations you can end up having identical IP addresses? (I know that my question, with the obvious implications of a female person involved, opens up a huge range of funny, silly, inquisitive or cynical remarks full of Schadenfreude . Just: Please dont! spare me the trouble. Thanks for any info!
