The Use of a Fully Qualified Domain Name (FQDN)

Many ISPs (Internet Service Providers) provide connectivity to their customers using dynamic
instead of static IP addressing. This means that a user's IP address does not remain constant over
time which presents a challenge for gateways attempting to establish VPN connectivity.
A Dynamic DNS (DDNS) service allows a user whose public IP address is dynamically assigned
to be located by a host or domain name. It provides a central public database where information
(such as email addresses, host names and IP addresses) can be stored and retrieved. Now, a
gateway can be configured to use a 3
address to establish bi-directional VPN connectivity.
To use DDNS, you must register with a DDNS service provider. Example DDNS Service
Providers include:
