What are the private IP address classes?

Private Address Ranges

  • Class A: 10.0. 0.0 to 10.255. 255.255.
  • Class B: 172.16. 0.0 to 172.31. 255.255.
  • Class C: 192.168. 0.0 to 192.168. 255.255.

What are the 3 private IP address ranges?

  • 10.0. 0.0 – 10.255. 255.255 (10.0. 0.0/8 prefix)
  • 172.16. 0.0 – 172.31. 255.255 (172.16. 0.0/12 prefix)
  • 192.168. 0.0 – 192.168. 255.255 (192.168. 0.0/16 prefix)

What are the private subnets?

Instances in the private subnet are back-end servers that don’t need to accept incoming traffic from the internet and therefore do not have public IP addresses; however, they can send requests to the internet using the NAT gateway (see the next bullet).

What is a Class C private IP address?

Class C addresses are used in small local area networks (LANs). Class C allows for approximately 2 million networks by using the first three octets for the network ID. In a class C IP address, the first three bits of the first octet are always 1 1 0.
