The router will first try the Preferred DNS Server to resolve a website’s URL IP address. If that IP
address fails to resolve the URL, the Router will then try the Alternate DNS Server. Your ISP must
provide this information to you. Click Apply to set the DNS configurations into the memory of the
Router.
Dynamic DNS
The Router supports DDNS, a service that maps Internet domain names to IP addresses. DDNS serves
a similar purpose to DNS in that DDNS allows anyone hosting a Web or FTP server to advertise a
public name to prospective users. Unlike DNS that only works with static IP addresses, DDNS works
with dynamic IP addresses, such as those assigned by an ISP or other DHCP server. DDNS is popular
with home networkers, who typically receive dynamic, frequently-changing IP addresses from their
service provider. To use DDNS, one simply signs up with a provider and installs network software on
their host to monitor its IP address. Please see your ISP for further information.
