The DNS record type that maps a domain or subdomain to an IP address or multiple IP addresses is the A (IPv4) or AAAA (IPv6) address. Here's a step-by-step explanation:

1. DNS stands for Domain Name System. It's a system that translates human-friendly domain names into the numerical IP addresses that computers use to communicate with each other.

2. When you type a domain name into your web browser, your computer uses DNS to retrieve the IP address for that site.

3. The A record is used for mapping the hostnames of a domain to the IPv4 address of the domain.

4. The AAAA record is used for mapping the hostnames of a domain to the IPv6 address of the domain.

5. So, if you have a domain or subdomain and you want to map it to an IP address or multiple IP addresses, you would use an A record for an IPv4 address or an AAAA record for an IPv6 address.

The other DNS record types you mentioned have different uses. A CNAME record is used to redirect one domain to another domain, an MX record is used to direct mail to an email server, and a PTR record is used for reverse DNS lookups.
