An IP address is a unique numerical identifier assigned to a device in a network, enabling communication and location tracking.

Elaboration:

• IPv4 (e.g., 192.168.1.1) uses 32-bit addresses.
• IPv6 (e.g., 2001:db8::ff00:42:8329) uses 128-bit addresses for more scalability.

IP addresses help in routing and device identification across networks.
