TP-Link TL-R470T User Manual page 93

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 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.
The Router, as a DDNS client, cannot provide DDNS service. Prior to using this function, be sure you
have registered on the official websites of DDNS service providers for username, password and
domain name. TL-R470T+ Router offers PeanutHull DDNS client, Dyndns DDNS client, NO-IP DDNS
client and Comexe DDNS client.
The Dynamic DNS can be implemented on DynDNS DDNS, No-IP DDNS, Peanuthull DDNS and
Comexe DDNS pages.
