Study Notes
IP Address Representation
- Binary representation includes values from 0 to 255 for each octet, represented in 8 bits.
- For example, 128 is represented as 10000000, 64 as 01000000, and 32 as 00100000.
Classful IP Addressing
-
Class A:
- Address Range: 1.0.0.0 to 126.255.255.255
- Default Subnet Mask: 255.0.0.0
- 126 Class A network IDs available, each allowing 16,777,214 hosts.
-
Class B:
- Address Range: 128.0.0.0 to 191.255.255.255
- Default Subnet Mask: 255.255.0.0
- 16,384 Class B network IDs available, each accommodating 65,534 hosts.
-
Class C:
- Address Range: 192.0.0.0 to 223.255.255.255
- Default Subnet Mask: 255.255.255.0
- 2,097,152 Class C network IDs available, each supporting 254 hosts.
-
Class D:
- Address Range: 224.0.0.0 to 239.255.255.255
- Used for multicast groups.
-
Class E:
- Address Range: 240.0.0.0 to 255.255.255.255
- Reserved for experimental use.
Network and Broadcast Addresses
- The first address in any address range is the network address, identified with all 0's in the host portion.
- Example Class A address: 115.0.0.0.
- The last address is the broadcast address, identified with all 1's in the host portion.
- Example Class A broadcast address: 115.255.255.255.
Host Addressing
- Each host must have a unique IP address within the same network.
- Common network portion is required for hosts on the same network.
- Subnet masks dictate the available IP address range for hosts.
- Host addresses cannot be the first or last in the range; reserved for network and broadcast addresses.
- Example Class A host range: 115.0.0.1 to 115.255.255.254.
Special Addressing
- Addressing a host can also be indicated by setting the network portion to all 0's.
- Local host addresses in the range 127.0.0.0 refer to the loopback interface, identifying the current host.
