870HN-51D’s WAN IP address changes dynamically. Dynamic DNS (DDNS) allows
you to access the P-870HN-51D using a domain name.
To use this feature, you have to apply for DDNS service at www.dyndns.org.
This tutorial shows you how to:
• Registering a DDNS Account on www.dyndns.org
• Configuring DDNS on Your P-870HN-51D

example.
