What is the purpose of non routable IP address lists as described by RFC1918?

RFC1918 Motivations As a solution, RFC1918 was drafted to enable private organizations to use these addresses internally. Private addresses can be used without asking permission to the Internet Assigned Numbers Authority (IANA), which governs the IP addresses assignment.

RFC 1918, or non-publicly routable IP Address space is one of those “stop-gaps”, along with NAT, that arose out of need to prolong IPv4 space and has become a de facto standard for many network operators for both security and rudimentary asset tracking purposes.

What is special about private IP addresses?

As far as Internet security is concerned, using a private IP address is more secure than using a public IP address, as private IP addresses are not directly visible on the Internet and are located behind NAT, which also ensures the security of the home network.

Why can’t a computer with an RFC 1918 IP address be used as a public facing Web server?

9. Why can’t a computer with an RFC 1918 IP address be used as a public-facing web server? A computer with an RFC 1918 address cannot be used as a server because client requests will not reach it. Routers prevent packets with RFC 1918 address in the destination address from leaving the networks.

RFC 1918 describes the use of IP address space deemed private by IANA, the Internet Assigned Numbers Authority (see, for example, RFC1918 – Address Allocation for Private Internets for details). Those instances where a host must be guaranteed to be isolated from the public Internet, for whatever reason.
