IP Fundamentals

What is an IP Address? (IPv4 vs IPv6)

A comprehensive technical explanation of Internet Protocol addressing, packet routing, and network interface identification.

Key Technical Takeaways

  • •IPv4: 32-bit numerical address expressed in dot-decimal notation (e.g., 192.168.1.1), providing ~4.3 billion unique addresses.
  • •IPv6: 128-bit hexadecimal address separated by colons (e.g., 2001:0db8:85a3::8a2e:0370:7334), supporting 3.4x10^38 unique addresses.
  • •Network Layer: Operating at Layer 3 of the OSI (Open Systems Interconnection) reference model.

An Internet Protocol (IP) address is a unique numerical identifier assigned to every device connected to a TCP/IP network. IP addresses enable network routers to deliver data packets to their intended destination across local networks and the global internet.
