R0106-HP MSR Router Series Layer 3 - IP Services Configuration Guide(V7)

HP and GNUDIP are common DDNS update protocols. The server-name parameter is the domain name
or IP address of the service provider's server using one of the update protocols.
The URL address for an update request can start with:
• http://—The HTTP-based DDNS server.
• https://—The HTTPS-based DDNS server.
• ods://—The TCP-based ODS server.
• gnudip://—The TCP-based GNUDIP server.
• oray://—The TCP-based DDNS server.
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 port number in the URL address is optional. If no port is specified, the system uses the default port
numbers: port 80 for HTTP, port 443 for HTTPS, and port 6060 for PeanutHull DDNS server.
The system automatically does the following:
• Fills <h> with the FQDN upon a DDNS policy application to the interface.
• Fills <a> with the primary IP address of the interface to which the DDNS policy is applied.
You can also manually specify an FQDN and an IP address in <h> and <a>. In this case, the FQDN
specified upon the DDNS policy application does not take effect. You are not encouraged to manually
change the <h> and <a> because your configuration might be incorrect. For more information about
applying DDNS policies, see "Applying the DDNS policy to an interface."
No FQD

or IP address can be specified in the URL address for update requests sent to the PeanutHull
DDNS server. You can specify the FQDN when applying the DDNS policy to an interface. The IP address
is the primary IP address of the interface to which the DDNS policy is applied.
TIP:
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.
Configuration prerequisites
Visit the website of a DDNS service provider, register an account, and apply for a domain name for the
DDNS client. When the DDNS client updates the mapping between the domain name and the IP address
through the DDNS server, the DDNS server checks the following:
• Whether the account information is correct.
• Whether the domain name to be updated belongs to the account.
Configuration procedure

Step Command Remarks
