Study Notes
Understanding IPv4 Address Classes and Subnet Masks
- An IP address like 192.168.10.55 with a subnet mask of 255.255.255.0 indicates the network portion as 192.168.10 and the host portion as 55.
- The subnet mask can make the same address appear on different networks, impacting network communication.
- For IPv4 communication, each computer needs an IP address, subnet mask, and a default gateway, typically a router, to connect outside the local network.
- IPv4 has classes of networks based on the first three bits of the IP address, affecting available networks and host capacity.
- Class A networks (0-127) are for large networks, offering 126 network addresses and up to 16,777,214 hosts.
- Class B networks (128-191) are for medium-sized networks, providing 16,384 networks and up to 65,534 hosts.
- Class C networks (192-223) are for smaller networks, allowing 2,097,152 networks with a maximum of 254 hosts each.
- Network addresses 0 and 127 are reserved, and 127.0.0.1 is the loopback address for network adapter troubleshooting.
- Table 7.2 shows IPv4 classes, their ranges, and default subnet masks, with reserved ranges for multicasts and testing.
- The notation "10.0.0.0/8" indicates the first 8 bits as the network portion, and "192.168.1.0/24" represents a Class C network with a default subnet mask.
- Examples of Class A, B, and C networks include Level 3 Communications, Microsoft, and Apple, respectively.
- The subnet mask impacts how an IP address is interpreted, affecting network communication and connectivity outside the local network.
Understanding IPv4 Addressing
- IPv4 addresses are 32-bit hierarchical addresses used to identify hosts on a network, typically written in dotted-decimal notation (e.g., 192.168.10.55).
- Each part of an IPv4 address represents 8 bits (1 byte) and can be written in binary (e.g., 11000000 10101000 00001010 00110111).
- Hierarchical addressing allows for routing packets between local networks and on the Internet, similar to how a street address helps in mail delivery.
- Telephone numbers also use a hierarchical addressing scheme, with area codes grouping telephone numbers into logical networks.
- Each IP address is made up of a network ID and a host ID, and the network portion does not have to be a specific fixed length.
- All host addresses on a network must be unique, and on a routed network, all network addresses must also be unique.
- Neither the network ID nor the host ID can be set to all 0s or all 1s, as this represents "this network" and "all hosts on this network" respectively.
- Computers use a subnet mask to differentiate the network ID and host address, where a bit set to 1 in the subnet mask makes the corresponding bit in the IP address part of the network ID.
- The highest number in IP addressing is 255, representing all bits in the octet being set to 1.
- Binary values in an octet range from 0 (00000000) to 255 (11111111).
- IPv4 addresses are structured to organize networks logically for efficient delivery between them and to identify individual nodes within a network.
- When working with IPv4 addresses, numbers will be between 0 and 255, and certain patterns may emerge when working with combinations of zeroes and ones.
