Frequently Asked Questions about
Dynamic Configuration Server
What is Nominum Foundation Dynamic Configuration Server?
Nominum Foundation Dynamic Configuration Server (DCS) is a commercial-grade DHCP server for organizations that need flexible, scalable and highly reliable DHCP services.
The Dynamic Host Configuration Protocol (DHCP) is an essential network service that automatically assigns IP addresses and network configuration settings to devices as they connect to an IP network. DHCP enables centralized management of network addresses, roaming access, and network access control.

100,000 clients with 24 hour leases are:
CPU: Pentium 800Mhz
RAM: 1 GB

Is Foundation Dynamic Configuration Server a version of the ISC DHCP server?
No, Foundation Dynamic Configuration Server is a completely new DHCP server, designed from the ground up to be robust, scalable and to provide high performance.
Nominum's engineers used the experience gained from writing the ISC DHCP reference implementation server to build a new server optimized for performance. Both servers are built to standards drawn from the RFCs concerning DHCP.

Is there a migration tool available to migrate my configuration file from the ISC DHCP server to Founcation Dynamic Configuration Server?
Yes. The Foundation Dynamic Configuration Server product includes a tool called isc2dcs that helps convert an ISC DHCP configuration file to Foundation Dynamic Configuration Server format. Because the two servers have some differences in how they handle some features, isc2dcs may not convert 100% of your existing configuration, but it will help you with the majority of common configuration elements.

Does Foundation Dynamic Configuration Server implement the DHCP Failover protocol?
Yes, Foundation Dynamic Configuration Server supports the DHCP failover protocol that is undergoing standardization now in the IETF. This protocol prevents users and devices from experiencing any interruption in service should one of the servers in the failover pair crash. Failover peers can also be configured to also provide load balancing.
