CHAPTER 18 DDNS 18.1 Overview DDNS (Dynamic Domain Name System) allows you to update your dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe or other services). This is for cases where the ISP gives the N4100 a dynamic IP address but you still want to use a domain name. You can also access your FTP server or Web site on your own computer using a domain name (for example, myhost.dhs.org, where myhost is a name of your choice), which will never change instead of using an IP address that changes each time you reconnect. Note: You must go to the Dynamic DNS service provider's website and register a user account and a domain name before you can use the Dynamic DNS service with your N4100. The Dynamic DNS service provider will give you a password or key. Note: If you have a private WAN IP address, then you cannot use Dynamic DNS. 18.1.1 What You Can Do in this Chapter Use the DDNS screen (Section 18.2 on page 160) to set the N4100 to use DDNS. 18.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. DYNDNS Wildcard Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname. N4100 User's Guide 159
