dhcp

Centralized network management is mandatory for today’s networks. DHCP, the dynamic host configuration protocol, is the standard way to distribute network configuration such as IP addresses, DNS server or routing information. This training course will teach the working of the DHCP protocol in IP networks, how client systems (Windows, MacOS, Linux, Solaris, mobile Devices) request DHCP information and how DHCP server can be managed in a stable and secure manner.
