3.12 DDNS
The DDNS (Dynamic DNS) service allows you to alias a dynamic IP address to a static hostname,
allowing your computer to be more easily accessed from various locations on the Internet.
Without DDNS, the users should use the WAN IP to reach internal server. It is inconvenient for the users
if this IP is dynamic. With DDNS supported, you apply a DNS name (e.g., www.xxx.com) for your server
(e.g., Web server) from a DDNS server. The outside users can always access the web server using the
www.xxx.com regardless of the WAN IP.
When you want your internal server to be accessed by using DNS name rather than using the dynamic IP
address, you can use the DDNS service. The DDNS server allows to alias a dynamic IP address to a static
hostname.
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.
DDNS is a method of keeping a domain name linked to a changing (dynamic) IP address. If you are
assigned a dynamic IP address and that address is used only for the duration of that specific connection.
With the WV202, you can setup your DDNS service and the WV202 will automatically update your
DDNS server every time it receives a different IP address.
