Study Notes
Class A
- Supports up to 16,777,214 nodes per network.
- Address range from 0.0.0.0 to 127.255.255.255; 127.0.0.0 reserved for loopback.
- Private addresses fall within the range of 10.0.0.0 to 10.255.255.255.
- Default subnet mask: 255.0.0.0.
- Network ID is represented by the first octet; the last three octets represent the node ID.
Class B
- Accommodates 65,534 nodes per network.
- Address range spans from 128.0.0.0 to 191.255.255.255.
- Private addresses: 172.16.0.0 to 172.31.255.255.
- Automatic Private IP Addressing (APIPA) range: 169.254.0.0 to 169.254.255.255.
- Default subnet mask: 255.255.0.0.
- Network ID is defined by the first two octets while the node ID is represented by the last two octets.
Class C
- Allows for 254 nodes per network.
- Address range from 192.0.0.0 to 223.255.255.255.
- Private addresses: 192.168.0.0 to 192.168.255.255.
- Default subnet mask: 255.255.255.0.
- Network ID is indicated by the first three octets, and the last octet represents the node ID.
- Most widely available address class due to the larger number of Class C networks.
Class D
