Explanation: RFC 1918, Address Allocation for Private Internets, defines three blocks of IPv4 address for private networks that should not be routable on the public Internet

There are three RFC 1918 networks: 10 0 0 0 8 172 16 0 0 12 192 168 0 0 16 You can subnet within each one of those ranges For instance, 192 168 1 0 24 is a subnet within the 192 168 0 0 16 network So is what you say you use: 192 168 2 0 24 It all boils down to binary math The mask length, the number after , is the number of bits in the 32-bit IP address which belong to the network subnet
- Why did the IETF specifically choose 192. 168 16 to be a private IP . . .
RFC 1918 which defines the private IP ranges, does not clarify on this point, so there is no definitive answer on why they chose 168 for the 16-bit block, but I posit that this was because the RFC was not released until 1996, after a huge number of registrations had already taken place because 192 is the first 8-bit block in the class C
