The DNS record types used to map hostnames to IP addresses are:
- A Record : Maps a hostname to an IPv4 address. It is the most common DNS record for this purpose and only supports IPv4 addresses. For example, an A record for example.com might point to 93.184.216.34
- AAAA Record : Maps a hostname to an IPv6 address. This record type is similar to the A record but is used for the newer IPv6 protocol, which provides a larger address space. For example, an AAAA record might point to an address like 3001:0db7:3c5d:0024:0000:0000:1a2f:3c1b
In summary, to map hostnames to IP addresses:
- Use an A record for IPv4 addresses.
- Use an AAAA record for IPv6 addresses.
These records allow browsers and other internet applications to resolve domain names into the IP addresses needed to connect to servers
