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.
Example
dnsaddress = "164.109.48.173"
lan.config.dns.address[1] = dnsaddress
Configure DNS address 1 to
"164.109.48.173"

Dynamic DNS registration domain; use a string of 255 characters or less
Details
This attribute holds the domain to request during dynamic DNS registration. Dynamic DNS registration works
with DHCP to register the domain specified in this attribute with the DNS server.
The length of the fully qualified host name (combined length of the domain and host name with separator
characters) must be less than or equal to 255 characters. Although up to 255 characters are allowed, you must
make sure the combined length is also no more than 255 characters.
Example
print(lan.config.dns.domain)
Outputs the present dynamic DNS domain. For
example, if the domain is "Matrix", the response
would be:
Matrix
