Configuration – Network > DNS Servers > DNS Server Update
“Dynamic DNS” is supported in accordance with RFC2136 and RFC2485. This allows units to
update specified DNS servers with their IP addresses when they first connect to the Internet
and at regular intervals thereafter. The parameters in this section control how the router
updates a specified DNS server with its IP address when it first connects to the Internet and
at regular intervals thereafter.
This is not to be confused with the popular dynamic DNS service dyndns.com, there is a
separate page for configuring the router to work with dyndns.com
Send an update to DNS Server a.b.c.d for
The IP address in this text box specifies the DNS server that should be sent the updated
information. The server must support “DNS Update messages”. Dynamic DNS is generally
offered as a subscription-based service by ISPs, but for a large number of deployed routers,
it may be more appropriate to set up a dedicated DNS server locally.
Name
The value in this text box specifies the member of the DNS zone to update. This name is
used in conjunction with the zone parameter (below) to uniquely identify the router. So, for
example, if the router has a name of “epos33”, the full address of the unit will be
“epos33.mycompany.com”.
Zone
The value in this text box specifies the DNS zone to update. When using Dynamic DNS it will
be necessary to have domain name (this may be purchased from an appropriate vendor).
This domain name, e.g. “mycompany.com” is what should be entered into the zone field.
When the default route changes
Interface x,y becomes active
The two radio buttons determine when the update is sent, i.e. when the default route
changes or when the specified interface becomes active. The drop-down list offers the
options of “PPP” or “Ethernet” and the text box is used to enter the instance number for the
specified interface.
