Which statement best describes an IP address?

• A. It is a unique numeric label for a device on a network
• B. It is a human-readable domain name
• C. It is a protocol for routing traffic
• D. It is a hardware component

Answer: (A)

An IP address is a unique numeric label assigned to a device on a network to identify it and help route data to it. Think of it like a street address for a computer or phone in the digital world. It enables routers to know where to send packets and how to reach the right device. IP addresses come in two main forms: IPv4 (like 192.168.1.5) and IPv6 (like 2001:0db8:85a3:0000:0000:8a2e:0370:7334). They can be static (stays the same) or dynamic (can change).

This isn’t a human-readable domain name (domain names are for humans and are translated to IPs by DNS), it isn’t a protocol (protocols are sets of rules for communication, not labels), and it isn’t hardware (it’s a software/assignment concept managed by devices and networks).
