Which Query Type is Required for an nslookup on an IPv6 Addressed Host?

A.

An nslookup is a tool used to query the DNS (Domain Name System) to obtain information about a domain or hostname. When an nslookup is performed on an IPv6 addressed host, a specific query type is required to retrieve the IPv6 address information from the DNS. The correct query type for an nslookup on an IPv6 addressed host is type=AAAA.

The query type parameter in nslookup specifies the type of DNS resource record to be queried. DNS resource records contain information about a domain, such as IP addresses, mail servers, and other domain-specific data. The type=AAAA query is used to obtain IPv6 address information.

Option B (type=ANY) is not the correct query type for an IPv6 addressed host because it retrieves all available types of DNS resource records for a domain, which can be a large amount of data and not specific to IPv6 addresses.

Option C (type=PTR) is used for reverse DNS lookups, where an IP address is used to query the DNS for the associated hostname. It is not used to retrieve IPv6 address information.

Option D (type=NAME-IPV6) is not a valid query type for nslookup.

In summary, the correct query type for an nslookup on an IPv6 addressed host is type=AAAA.
