What is an IP Address?

An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: identifying the host or network interface and providing the location of the host in the network.

IPv4 vs IPv6

There are two versions of IP addresses in use today:

• IPv4 (Internet Protocol version 4): Uses 32-bit addresses, allowing for about 4.3 billion unique addresses. Example: 192.168.1.1
• IPv6 (Internet Protocol version 6): Uses 128-bit addresses, allowing for approximately 340 undecillion unique addresses. Example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

Public vs Private IP Addresses

• Public IP Address: Assigned by your Internet Service Provider (ISP) and visible to the internet. This is what websites see when you connect to them.
• Private IP Address: Used within private networks (like your home or office network) to identify devices. These addresses are not routable on the internet.

• Setting up a home network or server
