Is this IPv4 and subnet combination public or private? [duplicate]

Solution 1:

Think of the /16 and /24's as a notation for how large a network is. A /24 is ~255 times smaller than a /16, but that does not mean it's not in the same range of addresses.

so yes, 192.168.0.0/24 is private, so is 192.168.1.0/24, as both are subsets of 192.168.0.0/16.

Solution 2:

Yes, that is correct.

Maybe the wikipedia article should be improved with if you are using a subnet mask of 255.255.0.0/routing prefix of 16 OR SMALLER.

Though I am not sure smaller is clear in this context. Smaller value? Smaller net? Smaller host part. Maybe 192.168/Foo where foo is 16 or larger. (Damm. Clear documentation is hard.)

If one source is confusing then I like to consult another source as reference. Serverfault has one such source at How does IPv4 Subnetting Work?
