Which DNS resource record would you query to obtain a domain's IPv4 address?

• A. MX record
• B. TXT record
• C. A record
• D. CNAME record

Answer: (C)

Obtaining an IPv4 address from a domain is accomplished by querying the record that maps a domain name to a concrete IPv4 address. This record stores the 32-bit IPv4 address in dotted decimal form, linking the domain directly to the numeric address. For example, a domain might resolve to 93.184.216.34 through this record. Other record types serve different purposes: the one that handles mail servers, not IP addresses; the one that holds arbitrary text; and the one that aliases a domain to another name. So, for IPv4 resolution, the record that directly provides the IPv4 address is the one you need. If IPv6 is involved, the corresponding type would be used to fetch an IPv6 address.
