1. Basics of IP Addresses and Ports

What is an IP Address?

An Internet Protocol (IP) address is a unique identifier assigned to each device connected to a network. It allows devices to locate and communicate with each other. IP addresses are categorized into IPv4 and IPv6, with IPv4 being the most commonly used.

IPv4 Addressing:

  • Consists of four octets separated by dots, e.g.,
  • Each octet ranges from 0 to 255.
  • Provides approximately 4.3 billion unique addresses.

IPv6 Addressing:

  • Uses eight groups of hexadecimal numbers separated by colons, e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
  • Designed to replace IPv4 due to the exhaustion of IPv4 addresses.
