Just because you're "in the industry" doesn't mean you know everything about everything. I'm not a developer so half the things discussed here on HN are waaaaay over my head.
> ARIN, RIPE NCC, APNIC, AfriNIC, LACNIC
These are the global agencies that manage the IP address allocations
As far as "bibles" go, however, Halabi's _Internet Routing Architectures_ is the BGP variant.
TCP/IP Illustrated might not mention CIDR since it was still pretty new when those books were written. My copies haven't been opened in years so I can't be sure.
If you've performed any subnetting in the last 15 years or so, however, I fully expect that you have encountered CIDR.
The very first line has enough information to know what it does:
"A tool to enumerate CIDRs by querying RIRs & BGP ASN prefix lookups"
In other words, it queries two sources (regional Internet registries -- the organizations referred to above -- and information from the BGP protocol) to enumerate blocks of IP addresses.
