Details
This attribute is an array of DNS (domain name system) server addresses. These addresses take priority for
DNS lookups and are consulted before any server addresses that are obtained using DHCP. This allows local
DNS servers to be specified that take priority over DHCP-configured global DNS servers.
You can specify up to two addresses. The address specified by 1 is consulted first for DNS lookups.
dnsAddress must be a string specifying the DNS server’s IP address in dotted decimal notation.
Unused entries are returned as "0.0.0.0" when read. To disable an entry, set its value to "0.0.0.0" or the
empty string "".
Although only two address may be manually specified here, the instrument will use up to three DNS server
addresses. If two are specified here, only one that is given by a DHCP server is used. If no entries are specified
here, up to three addresses that are given by a DHCP server are used.
