IP Address Ranges - TOML

IP Address Ranges are classifications of IPv4 and IPv6 address spaces used to identify devices on the internet. IANA manages global allocation, while RIRs (Regional Internet Registries) distribute addresses to each region. Classful addressing (Class A/B/C/D/E), private addresses (RFC 1918), special-purpose addresses, and various IPv6 prefixes are defined.
