Overview

HS DHCP is a DHCP Server library implemented in C language. HS DHCP implements the server part of DHCP as per RFC 2131

The use of HS DHCP C Source Library is Royalty Free.

Architecture of HS DHCP C Library

HS DHCP is delivered to the user with the following components:

• HS DHCP C source library implements core DHCP server functionality
• HsDhcpSrv: windows server application with C source code which uses HsDhcp
• HsTimer C library: provides HsDhcp with the necessary timer functionality
• HsList C Library: list management library

About DHCP Protocol

The Dynamic Host Configuration Protocol (DHCP) is an autoconfiguration protocol used on IP networks. Computers that are connected to IP networks must be configured before they can communicate with other computers on the network. DHCP allows a computer to be configured automatically, eliminating the need for intervention by a network administrator. It also provides a central database for keeping track of computers that have been connected to the network. This prevents two computers from accidentally being configured with the same IP address
