Dynamic Domain Name Service (Ddns) - Planet ADN-4000 User Manual

3.3.8.2 Dynamic DOMAIN NAME SERVICE (DDNS)

OVERVIEW
Dynamic DNS allows binding of domain names to hosts with dynamically assigned IP
addresses by a Dynamic Host Control Protocol (DHCP) server and updates the name server
with the new information about the host or the network. This is particularly useful to
broadband users hosting internet services such as File Transfer Protocol (FTP), Hyper Text
Transfer Protocol (HTTP) and Simple Mail Transfer Protocol (SMTP) on their local hosts
connected to the broadband network at home. Dynamic DNS allows access to such hosts
connected to the broadband networks using a domain name to exchange files, send receiv
email with highly personalized email addresses and host a website. The primary
requirement in such case is for the domain name to be associated with the ever changing IP
address of the host or the network. For more details about dynamic DNS please refer to
RFC 2136.
To provide such support for the feature described above, a client is installed in the host
serving the internet traffic directed to the domain. The client updates the IP address of the
host whenever the host renegotiates the IP address for any reason. The system provides
support for dynamic DNS allows the users to configure the following dynamic DNS servers
for DDNS service:
DynDNS.org: A free DNS service for hosts with dynamic IP addresses.
TZO: A service provider providing dynamic and static DNS services for a fee.
To use one of the providers mentioned above requires the users to register with the dynamic
DNS service provider the information about the host and the install the client software on the
host which can update the
in formation.
