R2511-HP MSR Router Series Layer 3 - IP Services Configuration Guide(V5)

With the DDNS client configured, a device can dynamically update the latest mapping between its
domain name and IP address on the DNS server through DDNS servers at www.3322.org or
www.oray.cn for example.
The DDNS update process does not have a unified standard but depends on the DDNS server that the
DDNS client contacts. The well-known DDNS service providers include www.3322.org, www.oray.cn
(also known as the PeanutHull server), and www.dyndns.com
.

Configuring a DDNS policy
A DDNS policy contains the DDNS server address, port number, login ID, password, time interval,
associated SSL client policy, and update time interval. After creating a DDNS policy, you can apply it to
multiple interfaces to simplify DDNS configuration.
The URL addresses configured for update requests vary by DDNS server.
• When a DDNS client contacts a DDNS server at www.3322.org by using HTTP, the URL address for
update requests should be configured as:
http://username:password@members.3322.org/dyndns/update?system=dyndns&hostname=<h
>&myip=<a>
• When a DDNS client contacts a PeanutHull DDNS server by using TCP, the URL address for update
requests should be configured as:
oray://username:password@phservice2.oray.net
Replace the parameters username and password in the URL with your actual login ID and password
registered at the DDNS service provider's website.
members.3322.org and phservice2.oray.net are the domain names of DDNS servers. The domain
names of PeanutHull DDNS servers can be phservice2.oray.net, phddns60.oray.net, client.oray.net,
ph031.oray.net, and so on. Determine the domain name in the URL according to the actual situation.
The system automatically fills <h> with the FQDN that is specified when the DDNS policy is applied to
the interface and automatically fills <a> with the primary IP address of the interface to which the DDNS
policy is applied. You may also manually specify an FQDN and an IP address in <h> and <a>,
respectively. After that, the FQDN that is specified when the DDNS policy is applied becomes ineffective.
HP recommends you do not change <h> and <a> in the URL address because your configuration might
be incorrect. For more information about applying DDNS policies, see "Applying the DDNS policy to an
in
terface."
NOTE:
The FQDN is the only identification of a node in the network. An FQDN consists of a local host name and
a parent domain name and can be translated into an IP address.
