RFC 1918 requests that organizations make use of the private Internet address space for hosts that require IP connectivity within their enterprise network, but do not require external connections to the global Internet.

As the Internet grew, this method of IP addressing resulted in a lot of wastage. For example, an organization that needs only 2 IP addresses will get a Class C address block. packetlife.net by Jeremy Stretch v2.0 IP V4 SUBNETTING Terminology Subnets CIDR /32 255.255.255.255 1 Subnet Mask Addresses Wildcard 0.0.0.0 /31 255.255.255.254 2 0.0.0.1 Subnet Mask Cheat Sheet If you are a network admin like us, this is a little sheet that you will continually need access to.
