> Right, and now your isp knows how many devices you have It sounds crazy today, but this is how it used to be with IPv4 back in the day. For instance at my first job, every employee's computer (Sun SPARCstations) and every server in the building was directly on the internet with a routable IP address. No firewalls in sight, no NAT. sendmail ran on every box, so incoming email was handled directly by your own workstation, from anywhere in the internet. So my email address was name@myhostname.company.com (we did have aliases and forwarding so name@company.com also worked). I ran FTP server and mailing lists and (slightly later) web sites from my workstation. This was peak decentralized internet and a wonderful time.
