NetX Duo DHCP Client Module Guide Resources

Last Updated:03/02/2018


Where can I find the references to module guide resources for the Express Logic NetX™ and NetX™ Duo DHCP Client module?


Information on the module guide itself and the associated resources and known issues are available here.


The Dynamic Host Configuration Protocol (DHCP) is a useful protocol to obtain IP addresses and network parameters. DHCP extends the basic functionality of BOOTP from a static address configuration to a dynamic IP address allocation by “leasing” an IP address to a client for a specified period of time. The DHCP can also be configured to allocate IP addresses in a static manner like BOOTP. An application’s IP address is one of the supplied parameters for the NetX Duo™ component; supplying an IP address poses no problem when the IP address is known to the application, either statically or through user-configuration. When the application doesn’t know or care what its IP address is the NetX Duo is initialized with a zero IP address; a DHCP client component added to NetX Duo can then dynamically obtain an IP address.

Note: The NetX™ DHCP Client is almost identical to the NetX Duo DHCP Client. NetX DHCP Client applications should build and run without any changes in a NetX Duo environment.

The module supports the following features:

  • The NetX Duo DHCP IPv4 Client module is compliant with RFC2132, RFC2131, and related RFCs.
  • Support for IPv4
  • Provides high-level APIs to:
    • Create and delete a DHCP Client instance
    • Start, stop, and reinitialize the DHCP Client (to restart the DHCP Client protocol)
    • Request a specific IP address from the server
    • Specify the network interface to run the DHCP Client on
    • Supply an application-created packet pool to the DHCP Client
