Re: [Info] Enterprise IP Addressing Scheme
There are some valid reasons of using Non-RFC-1918 IP version 4 addresses for internal networking. Following are some of those reasons.
* The internal network has been so huge that you cannot use RFC-1918 IP addresses for everything. In this case, you can only use RFC-1918 IP addresses for point-to-point network while hosts (such as router's Loopback interfaces, servers, printers, PC) have to use non-RFC-1918 IP addresses
* There are overlapping IP schemes within the internal network when you try to use RFC-1918 IP addresses for everything. This case usually applies when there are two companies merging or one company acquires other companies that the IP scheme overhaul usually result in using non-RFC-1918 IP addresses for hosts
