PPPoE and DDNS for Internet Connection

Technology Description
PPPoE (Point-to-Point Protocol over Ethernet) is a network protocol for encapsulating Point-to-Point Protocol (PPP)
frames inside Ethernet frames. It is used mainly with DSL services where individual users connect to the xDSL modem
over Ethernet. to build up network connection.
DDNS (Dynamic Domain Name Server) is a method, protocol, or network service that provides the capability for a
networked device using the Internet Protocol Suite, such as an IP router or computer system, to notify a domain name
server to change, in real time, the active DNS configuration of its configured hostnames, addresses or other information
stored in DNS. When getting the connection through PPPoE and the IP address is floated, end users may not configure
device server. However, through DDNS method, it’s easy for different IP domain users to connect to IR/IAR/TAR series
device servers.

PPPoE Benefits
PPPoE enables clients to adopt the traditional dial-up access mode, which allows end users to use the familiar hardware
and similar software to access the Internet. Moreover, clients can also use Ethernet adapters to connect PCs and xDSL
modems, which allow PCs to share xDSL lines and thus saves investment.

DDNS Benefits

With DDNS, there is no need to go from PC to PC setting up static addresses every time your network infrastructure
changes. Moreover, you only need the addresses that would be used simultaneously, rather than having one for every
possible user of IP.
