Networking Addressing Overview

MAC Address: A unique 48-bit physical address assigned by manufacturers to identify network devices; usually fixed and unchangeable.

IPv4 Addressing

IPv4: Comprises 32 bits divided into four 8-bit groups (octets); currently the oldest version of the IP protocol.
Subnetting: The process of dividing an IP address range into smaller ranges, allowing for multiple networks to use parts of the same IP range.

Understanding Subnetting

Subnet Mask: A binary number that defines the network portion of an IP address. It consists of a series of 1s followed by 0s, indicating the split between the network and host identifiers.
Logical AND Operation: Used to isolate the network address from an IP address by comparing it with the subnet mask.

Classful IP Addressing

Classful Addressing: Early IP addressing categorized as Class A, B, and C; defines network ID and host portions of the address. Only Classes A, B, and C are typically used.

Default Settings and Host Capacity

Default Subnet Mask for Class C: 255.255.255.0; addresses from 192 to 223.
Class C Host Support: Supports up to 254 hosts per network; there are 2,097,152 such networks.

Automatic Private IP Addressing (APIPA)

APIPA Range: IP addresses assigned automatically when a DHCP server is unreachable, using the Class B block from 169.254.0.0 to 169.254.255.255.

Recognizing Private IP Ranges

Private IP Addresses: Include ranges 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255. The address 128.0.0.0 to 128.255.255.255 is not a private IP range.

CIDR Notation

CIDR Notation: Expresses subnet masks in shorthand; for example, the subnet mask 255.255.255.0 is represented as /24.

Binary and Hexadecimal Conversions

Binary Representation of 180: 1011 0100; calculated by summing corresponding binary values.
Binary Equivalent of 255.255.0.0: Written as 11111111.11111111.00000000.00000000.
IPv6 Addressing: Utilizes 128 bits; expressed in hexadecimal format to accommodate a larger address space.
Hexadecimal Equivalent of 255: Conversions yield FF; derived from binary representation 1111 1111.
