Usage: add dnsservers [name=][address=][[index=]][[validate=]yes|no]
name - The name or index of the interface where DNS
servers are added.
address - The IP address for the DNS server you are adding.
index - Specifies the index (preference) for the specified
DNS server address.
validate - Specifies whether validation of the DNS server setting
will be performed. The value is yes by default.
Remarks: Adds a new DNS server IP address to the statically-configured list.
By default, the DNS server is added to the end of the list. If an
index is specified, the DNS server will be placed in that position
in the list, with other servers being moved down to make room.
If DNS servers were previously obtained through DHCP, the new
address will replace the old list. If Validate switch is yes,
then the newly added DNS server is validated.
