DNS client

Use the following command to specify the type of DNS query to be sent first:
If you set the request version to ipv4, the DNS application sends an A query first, to resolve
the hostname with an IPv4 address. If no A record is found for that hostname (no IPv4 address
for that hostname) an AAAA query is sent to resolve the hostname with a IPv6 address.
If you set the request version to ipv6, the DNS application sends an AAAA query first, to
resolve the hostname with an IPv6 address. If no AAAA record is found for that hostname (no
IPv6 address for that hostname) an A query is sent to resolve the hostname with an IPv4
address.
