5.7 Dynamic DNS (Domain Name System)
If Broadband Router acquired its WAN IP address via the DHCP or PPPoE schemes,
its IP address is likely to be different from its previous one after Broadband Router is
rebooted or PPPoE session is re-established. This creates difficulty for some
applications due to dynamic nature of Broadband Router WAN IP address. The
“
Dynamic DNS
” feature provides a solution to this problem by automatically
updating its WAN IP address to a DDNS service provider.
Many Internet Service Providers provide a kind of service called
Dynamic DNS
service, which allows you to register a fixed domain name. Every time when
Broadband Router gets a new dynamic public IP address, it informs the DDNS service
provider with this new IP address; then any connections toward to your domain name
will be mapped to the updated IP address.
Step 1.
Select DDNS service provider.
Broadband Router supports two DDNS service providers,
www.no- ip.com
or
www.dyndns.org
. Browse to the DDNS service provider ’s web page and
register a new account there. Your DDNS service provider will provide you
the account ID and password.
