What is an IP address?

• A. Internet Protocol Address
• B. Internet Protocol Version
• C. Internal Processing Identifier
• D. Internet Protocol Addressing scheme

Answer: (A)

An IP address is the numeric label assigned to a device that participates in an IP network, used to identify that device and to route traffic to it. IP stands for Internet Protocol, and the address is what allows packets to travel from one device to another across interconnected networks. There are two main versions in use: IPv4 and IPv6. IPv4 uses 32-bit addresses written as four decimal numbers separated by dots (for example, 192.168.0.1). IPv6 uses 128-bit addresses shown as eight groups of four hexadecimal digits (for example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334). Addresses can be public, routable on the Internet, or private, reserved for use within local networks and often translated by network address translation (NAT) when they need to reach the wider Internet. Addresses can be assigned permanently (statically) or assigned automatically by a server (dynamically, via DHCP). What this term is not: it isn’t a version of the protocol itself (“Internet Protocol Version”) or a broad scheme describing how addressing is done (“Internet Protocol Addressing scheme”). It also isn’t an internal processing identifier; that term isn’t used for identifying a device on a network.
