Which DNS Record Connects a Domain Name to an IPv4 Address?
Learn how DNS A records work to connect domain names to IPv4 addresses. Discover the crucial role this fundamental DNS record plays in routing internet traffic and website navigation.
Question
Which DNS record type is used to associate a domain name with an IPv4 address?
A. MX record
B. CNAME record
C. Quad A (AAAA) record
D. A record
Answer
D. A record
Explanation
When you type a website name into your browser, the internet relies on a DNS “A” record—short for “Address” record—to figure out exactly where to send you. Because computers communicate using numerical IP addresses rather than human words, the A record acts as a translator, mapping the easy-to-read domain name (like example.com) directly to its corresponding IPv4 address. If a website uses the newer, longer IPv6 format, it uses an “AAAA” record instead, but for standard IPv4 addresses, the A record is the fundamental backbone of internet navigation.
