Details
Dynamic DNS registration works with DHCP to register the host name with the DNS server. The host
name is specified in the
lan.config.dns.hostname
attribute.
Example
print(lan.config.dns.dynamic) Outputs the dynamic registration state.
If dynamic DNS registration is enabled, the
response is:
1.000
Also see
lan.config.dns.hostname (on page 7-96)
lan.restoredefaults() (on page 7-101)
lan.config.dns.hostname
This attribute defines the dynamic DNS host name.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes Not applicable Nonvolatile memory
Instrument specific
(see
Details )
Usage
hostName = lan.config.dns.hostname
lan.config.dns.hostname = hostName
hostName The host name to use for dynamic DNS registration; the host name must:
•
be a string of 15 characters or less
•
start with a letter
•
end with a letter or digit
•
contain only letters, digits, and hyphens
Details
This attribute holds the host name to request during dynamic DNS registration. Dynamic DNS
registration works with DHCP to register the host name specified in this attribute with the DNS server.
The factory default value for
hostName
is
"K-<model number>
-
<serial number>"
, where
<model number>
and
<serial number>
are replaced with the actual model number and serial
number of the instrument (for example,
"K-707B
-
1234567"
). Note that hyphens separate the
characters of
hostName
.
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 15 characters can
be entered here, care must be taken to be sure the combined length is no more than 255 characters.
Setting this attribute to an empty string (in other words, setting this attribute to a string of length zero,
or one consisting entirely of whitespace characters) will revert the host name to the factory default
value.
Example
print(lan.config.dns.hostname) Outputs the present dynamic DNS host name.
