Set Up and Manage Dynamic DNS
Internet service providers (ISPs) assign numbers called IP addresses to identify each Internet account. Most ISPs
use dynamically assigned IP addresses. This means that the IP address can change at any time. You can use the
IP address to access your network remotely, but most people do not know what their IP address is or when this
address changes.
To make it easier to connect, you can get a free account with a Dynamic DNS service that lets you use a domain
name to access your home network. To use this account, you must set up the modem router to use Dynamic DNS.
Then the modem router notifies the Dynamic DNS service provider whenever its IP address changes. When you
access your Dynamic DNS account, the service finds the current IP address of your home network and automatically
connects you.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic DNS service does not
work because private addresses are not routed on the Internet.
Your Personal FTP Server
With your customized free URL, you can use FTP to access your network when you are not home through Dynamic
DNS. To set up your FTP server, you must register for a NETGEAR Dynamic DNS (DDNS) service account and
specify the account settings.

The modem router supports only basic DDNS, and the login and password might not be
secure.You can use DDNS with a VPN tunnel for a secure connection.
