The ISC is implementing a DHCP server for Unix systems. As I write this, DHCP 2.0 is the production version and in common use. DHCP 3.0 is in beta. The 2.0 distribution does not support dynamic DNS updates. The 3.0 beta does support dynamic DNS, but the documentation includes warnings about the beta not being final, so use it at your own risk (and only if you need the features). A production release may be available by the time you read this, however. As with BIND, DHCP can be retrieved from the ISC ftp site: ftp://ftp.isc.org/isc/dhcp/. See the Web site at http://www.isc.org/products/DHCP/ for more information about the available releases, their status, and their features. I will not even try to describe the design, implementation, and usage issues connected with DHCP; I will simply discuss some DHCP/DNS integration issues.

Mixing DNS and DHCP Implementations

Some people want to use Windows DHCP with BIND DNS, or vice versa. I have not had the opportunity to try either combination, but the general advice available on the net about this is "don't". It apparently works better if you keep Windows DHCP paired with Windows DNS, and ISC DHCP paired with ISC DNS.
