DNS client
DNS commands support both IPv4 and IPv6 addresses. Link-local addresses are not supported.
Use the following command to specify the type of DNS query to be sent first:
If you set reqver v4, 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 reqver v6, 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 a IPv4 address.
