DDNS (Dynamic DNS) server provides a fixed domain name for DDNS client and maps its
latest IP address to this domain name. Dynamic DNS (DDNS) is an Internet service that
allows controller with varying public IP addresses to be located using Internet domain
names. To use DDNS, you must setup an account with a DDNS provider and set up an
account with a DDNS service, the host & domain name, username, password detail will
be provided by the account provider. It allows address, which enables the Internet hosts
to access the router or the hosts in LAN using the domain names. As many ISPs use
DHCP to assign public IP addresses in WAN, the public IP address assigned to the client is
unfixed. In this way, it’s very difficult for other clients to get the latest IP address of this
client for access.
DDNS (Dynamic DNS) server provides a fixed domain name for DDNS client and maps its
latest IP address to this domain name. When DDNS server works, DDNS client informs the
DDNS server of the latest IP address, the server will update the mappings between the
domain name and IP address in DNS database. Therefore, the wireless users can use the
same domain name to access the DDNS client even if the IP address of the DDNS client
has changed. DDNS is usually used for the Internet users to access the private Website
and FTP server, both of which are established based on Web server.
