A modest proposal: IPv7½
Needs only one (decimal) digit for an IP address, statically allocated as follows.
1 - The Register
2 - Facebook
3 - Netflix
4 - Google
5 - Microsoft (just block this one to stop Win10 from slurping)
6 - AliExpress
7 - You printer (replacing 192.168.X.X)
8 - Your boss (replacing 10.X.X.X)
9 - yourself (for return packages. Carrier-grade NAT is used in case somebody else wants to use the Internet at the same time)
0 - localhost
Nice small routing tables.
