What is an IP Address?
An IP address, or Internet Protocol address, is a unique numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. It serves two principal functions:
- Network Interface Identification: It identifies the host or more specifically its network interface.
- Location Addressing: It provides the location of the host in the network, enabling the establishment of a path to that host.
Types of IP Addresses
- IPv4: The original IP version, defines an IP address as a 32-bit number.
- IPv6: A newer version using 128 bits for the IP address, standardized to accommodate the growing number of internet users.
Public vs. Private IP Addresses
- Public IP Addresses: These are used to identify and communicate with devices on a global scale.
- Private IP Addresses: These are used within a private network and are not globally unique.
