Why each option
RFC 1918 defines the private IPv4 address ranges reserved for use within private networks and not routable on the public internet.
RFC 1919 discusses NAT concepts but does not define private address ranges.
RFC 1918, published by IANA, designates three address blocks as private and non-routable on the public internet: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. Routers on the public internet are configured to drop packets sourced from or destined to these ranges, preventing them from traversing the global routing table.
RFC 2036 is not associated with private IP addressing standards.
RFC 2050 covers IANA IPv4 address allocation policy, not the definition of private non-routable ranges.
RFC 5150 is unrelated to private IP address space definitions.
