On his website at xkcd.com, Randall Munroe has an excellent ‘comic’ map of the IPv4 address space.
The map shows 256 numbered blocks each representing one /8 subnet of the available IP address space. Of particular interest are the blocks sold directly to governments and companies in the early 1990’s before the Regional Internet Registries took over allocation.
I’m fascinated that there were some some more foresightful companies than other, including:
- Hewlett Packard
- Ministry of Defence
I wonder where MSFT was during this gold-rush?!?
