4.3 Services

4.3.1 DHCP Service

DHCP adopts a Client/Server communication mode. The Client sends a configuration request to the Server, which feeds back the corresponding configuration information, including the distributed IP address to the Client, to achieve the dynamic configuration of the IP address and other information.

  • The duty of the DHCP Server is to distribute an IP address when a workstation logs on and ensure each workstation is supplied with a different IP address. The DHCP Server has simplified some network management tasks requiring manual operations to the largest extent.
  • As a DHCP Client, the device receives the IP address distributed by the DHCP server after logging in to the DHCP server, so the Ethernet interface of the device needs to be configured into automatic mode.

To enable the DHCP service, select 【Services】→【DHCP Service】 from the navigation tree, then enter the "DHCP Service" page.

Table 4-3-1 DHCP Service Parameters

Parameters Description Default
Enable DHCP Enable DHCP service and dynamically allocate IP address Enable

IP Address Set a statically specified IP address 192.168.2.2
Host Set the hostname N/A

4.3.2 DNS

DNS (Domain Name System) is a DDB used in TCP/IP application programs, providing switching between domain names and IP addresses. Through DNS, users can directly use meaningful domain names which can be easily memorized, and the DNS Server in the network can resolve the domain name into the correct IP address. Manually set the DNS; use DNS via dialing if it is empty. Generally, it only needs to be set when a static IP is used on the WAN port.

Click the 【Services】→【Domain Name Service】 menu in the navigation tree to enter the "Domain Name Service" interface.

Description For recording the significance of the IP address <=> domain name N/A

When enabling DHCP, the DHCP relay is also enabled automatically. The relay cannot be disabled without disabling DHCP.

4.3.4 DDNS

DDNS maps the 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. DDNS captures the 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.

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

The CR202 DDNS service types include QDNS (3322)-Dynamic, QDNS(3322)-Static, DynDNS-Dynamic, DynDNS-Static, DynDNS-Custom, and No-IP.com.
