Why are domain names easier to remember than IP addresses?

• A. They are harder to remember than IPs
• B. They are human-readable addresses mapped to IPs
• C. They are only used for internal networks
• D. They are not used in web browsing

Answer: (B)

Domain names are easier to remember because they are human-friendly labels that the network translates into the numeric IP addresses computers use to route traffic. The Domain Name System (DNS) maps each readable name, like example.com, to one or more IP addresses behind the scenes. This separation lets people rely on memorable words and brands, while the actual routing relies on numbers that computers understand. DNS also lets a single domain point to different IPs over time (for load balancing or infrastructure changes) and uses caching to speed up repeated lookups. In typical web browsing, you type a domain name, DNS resolves it to an IP, and your browser connects to that address. The other ideas—being harder to remember, only for internal networks, or not used in web browsing—don’t reflect how the internet actually works.
