The DNS record that points to the host's IP address and is commonly used for IPv4 is:

Explanation:
In DNS, translating a human-friendly hostname into a numeric address that devices can connect to is essential for routing traffic. The record that binds a domain name to its IPv4 address is the A record. It associates the hostname with a 32-bit IPv4 address, enabling clients to reach the host over IPv4. For IPv6, the equivalent is the AAAA record. Other common records have different roles: MX directs mail to a mail server, NS designates the authoritative name servers for a domain, and SOA holds authority and caching information for the zone. So, for mapping to an IPv4 address, the A record is the correct choice.
