Which of the following DNS record types holds an IP address?

The record type that holds an IP address is the A record. This type of record maps a domain name to its corresponding IPv4 address, allowing users to access a website or other services by typing in the domain name instead of the numerical address. When a DNS query is made for a domain, the A record provides the necessary information for the DNS resolver to return the correct IP address to connect to the desired service.

In contrast, the MX record is used for directing email traffic by specifying the mail servers responsible for accepting mail on behalf of a domain. CNAME records function as an alias for a domain name, allowing one domain to point to another without providing a direct IP address, while TXT records hold arbitrary text data associated with the domain, often used for verification and other purposes.
