What is an IP address?

An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a network. It serves two main purposes: identifying the host or network interface and providing the location of the device in the network, which enables data routing between devices.

Why is an IP address important?

IP addresses are crucial because they:

• Enable devices to communicate with each other over networks.
• Help route data to the correct destination on the internet.
• Allow network administrators to implement security measures such as firewalls and access controls.
• Support functionalities like geolocation, which can enhance user experience through localized content.

What is the difference between IPv4 and IPv6?

IPv4 and IPv6 are two versions of Internet Protocol:

• IPv4: Uses a 32-bit address scheme, which allows for about 4.3 billion unique addresses. It is the most widely used version but is running out of available addresses.
• IPv6: Uses a 128-bit address scheme, providing a vastly larger address space to accommodate the growing number of devices. It also introduces improvements in routing and network configuration.
