Study Notes
Class A IP Addresses
- Utilizes the first octet to designate the network ID.
- Remaining 24 bits (last three octets) are for host identification.
- The first bit is always set to zero, limiting the first octet value to a maximum of 127.
- Class A address range: 0.0.0.0 to 127.255.255.255.
Class B IP Addresses
- Employs the first two octets (16 bits) for network ID.
- Last two octets designated for host information.
- All hosts in a Class B network share the same first two octets.
- First two bits must be set to one and zero, allowing first octet values from 128 to 191.
- Class B address range: 128.0.0.0 to 191.255.255.255.
Class C IP Addresses
- Defines the network ID with the first three octets.
- Last octet is for host identification.
- Supports the fewest hosts due to only one octet being used for host ID.
- Class C address range: 192.0.0.0 to 223.255.255.255.
Class D IP Addresses
- Specifically reserved for multicasting purposes.
- Class D address range: 224.0.0.0 to 239.255.255.255.
Class E IP Addresses
- Allocated for experimental use and research purposes.
- Class E address range: 240.0.0.0 to 255.255.255.255.
