What is a DHCP Subscription?
ISC DHCP software itself is completely free. However, we recommend our DHCP support subscription to get the most benefit from it.
Why pay for technical support?
It is critical for your business to keep your users connected at all times. With an ISC DHCP subscription, our support engineers will assist you in ensuring that your ISC DHCP implementation is reliable and dependable.
Access to Professional Technical Support
ISC DHCP is probably the most well-known and widely-used DHCP software on the Internet, with client, relay and server applications included. However, it is not trivial to implement and maintain a campus or organization-wide dynamic host configuration system. With a support subscription, we will help you deal with the issues that arise in your implementation and help you get the most out of our free software.
Sustain the Open Source You Rely On
ISC DHCP is very mature software, but it still needs regular maintenance. Operating system software updates and new device types can cause conflicts or instability. Your support contract helps to fund ISC’s work in sustaining ISC DHCP, and developing a successor product, Kea.
If you rely on ISC DHCP, whether you get it from ISC, from an operating system download site, or through a commercial application built on top of ISC DHCP, it is your responsibility to also contribute to maintaining this critical bit of the Internet infrastructure. While we do welcome donations, we get nearly all our financial support from paid subscriptions for open source support. Unlike a foundation, or advertising-supported business, this keeps us focused on our core mission, enabling the Internet and serving the users of our software.
