Earlier quoted context omitted.
At the time TCP/UDP were invented, keeping packet size small was very important. A string or GUID as addressing information would have been out of the question. (If there wasn't a need to distinguish multiple clients on the same machine, we might have only had 255 ports!) A standard port for HTTP servers is needed, as most HTTP clients don't support DNS SRV records. That said, in the IPv6 world there's no technical r…
> in the IPv6 world there's no technical reason you can't just let every service bind a different IP address. I'm not a networking expert, but is that true that you can create multiple ip's for a single device using ipv6? Sounds like it would end up very messy.
You can do that, provided that the network routes multiple IPs (or a whole prefix) to the device. It tends to be pretty messy keeping track of all the addresses in the OS configuration, but that's an opportunity for OSes to get better.
