Question

What is the host address (A or AAAA) used for?

1) Mapping a host name to an IP address
2) Mapping an IP address to a host name
3) Translating a host name to a MAC address
4) Translating a MAC address to a host name

Answer 1

The host address records A and AAAA are used to map a host name to an IP address, with A for IPv4 and AAAA for IPv6. They are part of the DNS, which enables devices to locate each other on the internet.

Step-by-step explanation:

The host address records, commonly known as A and AAAA records, are used for mapping a host name to an IP address. An A record is used to map a host name to an IPv4 address, while an AAAA record is used for IPv6 addresses. These records are essential parts of the Domain Name System (DNS), which is the internet service that translates human-readable domain names (like www.example.com) into machine-readable IP addresses so that networked devices can locate and communicate with each other.
