What is RFC 1918? | Yahoo Answers Dec 20, 2006 IPv4 Private Address Space and Filtering - American According to standards set forth in Internet Engineering Task Force (IETF) document RFC-1918, the following IPv4 address ranges are reserved by the IANA for private internets, and are not publicly routable on the global internet: 10.0.0.0/8 IP addresses: 10.0.0.0 – 10.255.255.255; 172.16.0.0/12 IP addresses: 172.16.0.0 – 172.31.255.255 Forbidden Rejected request from RFC1918 IP to public May 13, 2019
RFC 1918 2: The need to prolong the life of IPv4 IP addresses (AGAIN) RFC 1918 was codified in 1996 by Y. Rekhter of Cisco Systems, B. Moskowitz of Chrysler Corp., D. Karrenberg of RIPE NCC, G. J. de Groot of RIPE NCC, and E. Lear Silicon Graphics, Inc.
The RFC1918 ranges are used everywhere without proper planning. For instance, 192.168.1.0/24 , 192.168.100/24 , 192.168.254.248/2 .. etc. in the hub and some other 192.168.168.X/24 ranges on spokes. (this configuration is for the Hub) So for the VPN to work, I need NAT exemptions. Currently the Nat exemption is based on ASA 8.0 and has about 70 Announcing EC2 DNS Support for Non-RFC 1918 Address Ranges Oct 24, 2016 History for draft-ietf-cidrd-private-addr-05
