- What range of IP addresses is represented by the CIDR block 172. 16. 0. 0 12?
Thus this block represents the IP addresses from 172 16 0 0 to 172 31 255 255 The netid is 1010 1010 0001 and the CIDR block contains 2^20 addresses * I fully understand that the CIDR block has 2^20 host ID addresses and that it is in a Class B network
- How to divide an IPv4 network into subnets of different sizes as . . .
I need to divide a network 172 16 0 0 12 into 3 different subnets for different purposes One of them needs 6 host addresses, another 85 host addresses and the last 100 host addresses
- How to tell if an ipv4 address is public or private? - network
172 16 0 0 12 IP addresses: 172 16 0 0 – 172 31 255 255 192 168 0 0 16 IP addresses: 192 168 0 0 – 192 168 255 255 My doubt is Should private addresses be only from the above mentioned ip range or can they have any ip address range? Can public ip address be from the above mentioned ip addresses ? If so then will that be valid in the internet?

2 Don't do that! 172 32 0 0 11 is assigned to T-Mobile It's announced to the DFZ (since 2012) and most likely in use for real Internet traffic If you squat on that address space, some portion of the Internet will become inaccessible to your network!

- Why 192. 168. *. * for local addresses?
This is correct At the time, glassful addressing was in use To accommodate networks of different sizes, one class A, 32 class B and 256 class C networks were designated Why 10, 172 16 and 192 168? Because it was an afterthought and those were available
