In a usenet discussion mentioning fidonet adresses and the fact that ipv6 addresses are that much bigger I had to look in the original Fidonet technical standard 001 how big zone / net / node (and point) addresses could be. Those are all 2-byte unsigned numbers, which gives us:
  • Potential fidonet node addresses: 65536*65536*65536 = 281474976710656
  • Potential fidonet point addresses: 65536*65536*65536*65536 = 18446744073709551616
To compare:
  • Potential IPv4 addresses: 256*256*256*256 = 4294967296
  • Potential IPv6 addresses: 2^128 = 340282366920938463463374607431768211456
So Fidonet was by design bigger than IPv4. And I'll keep promoting IPv6!

I'm skipping all kinds of 'overhead' and 'reserved' addresses.
