You don't send an email to an IP address. You send it to an account on a server. Also, with IPv6, a LAN has a gazillion addresses (2^64 or 18.4 billion, billion).
And the server writes your home IP into the received headers. At least some servers do.
Yep, but you didn't use my address to send the email. It was sent to your SMTP server, then forwarded to my ISP's server, where my email client found it.
The point is that the exact IP of your computer is published and can be used to target an attack. -- Cheers / Saludos, Carlos E. R. (from 15.5 x86_64 at Telcontar)
