Looking at the past
A coworker sent me a link to RFC 1375, Suggestion for New Classes of IP Addresses, where a few new series of address space are broken out to handle /30’s and such. Compare this to CIDR, where we finally treat IP addresses as a 32 bit integer and move completely classless. What would the Internet look like today if we’d have chosen to stay classful?
For those interested in the stuff, here are a couple of good papers/reports about address space:
IPv4 - How long have we got?
The CIDR Report. Who’s abusing the system? I check here every so often to make sure my AS doesn’t inadvertantly show up!
