3.3 SERVICES
3.3.1 DHCP Service
DHCP adopts Client/Server communication mode. Client sends configuration request to Server which feeds back corresponding configuration information, including distributed IP address to the Client to achieve the dynamic configuration of IP address and other information. The duty of DHCP Server is to distribute IP address when Workstation logs on and ensure
each workstation is supplied with different IP address. DHCP Server has simplified some network management tasks requiring manual operations before to the largest extent. As DHCP Client, the device receives the IP address distributed by DHCP server after logging
21

in the DHCP server, so the Ethernet interface of the device needs to be configured into an

automatic mode.

To enable the DHCP service, find the navigation tree, select Services >> DHCP Service, then enter

"DHCP Service" page.

3.3.2 DNS
DNS (Domain Name System) is a DDB used in TCP/IP application programs, providing switch between domain name and IP address. Through DNS, user could directly use some meaningful domain name which could be memorized easily and DNS Server in network could resolve the domain name into correct IP address. Manually set the DNS, use DNS via dialing if it is empty. Generally, it needs to set only when static IP is used on the WAN port. Click the "Service>>Domain Name Service" menu in the navigation tree to enter the "Domain Name Service" interface.

3.3.4 DDNS

DDNS maps user's dynamic IP address to a fixed DNS service. When the user connects to the

network, the client program will pass the host's dynamic IP address to the server program on the

service provider's host through information passing. The server program is responsible for

providing DNS service and realizing dynamic DNS. It means that DDNS captures user's each

change of IP address and matches it with the domain name, so that other Internet users can

communicate through the domain name. What end customers have to remember is the domain

name assigned by the dynamic domain name registrar, regardless of how it is achieved.

DDNS serves as a client tool of DDNS and is required to coordinate with DDNS Server. Before

the application of this function, a domain name shall be applied for and registered on a proper

website such as www. 3322. org.

InRouter305 DDNS service types include QDNS (3322)-Dynamic, QDNS(3322)-Static,

DynDNS-Dynamic, DynDNS-Static, DynDNS-Custom and No-IP.com.
