Support ISC with your financial contribution

We do not have an endowment, and we are not funded by “the government.”

We employ full-time, professional software engineers to develop and maintain the code that you can download for free.

Please click the PayPal or Patreon buttons above to make a one-time or recurring donation to support Internet Systems Consortium and our open source work.

We welcome sponsorships! If you are passionate about Internet security or privacy, or want to see a new feature implemented, contact us about sponsorship at

You need viable, production-quality open source. Open source lowers the barriers for participation on the Internet for everyone, and removes the necessity to “reinvent the wheel” for new entrants.

Planned projects include:

  • BIND 9 refactoring and new feature development
  • BIND maintenance releases on 9.11, 9.14 trains
  • Kea DHCP feature releases 1.6 and 1.7, focusing on configuration backends, performance, and scalability
  • Continued work on IETF standards

With your donation of $10 or more, you will receive an email from us acknowledging the gift and your name will be added to the list of donors on this page. For donations of $1000 or more, we will add a link to your website for one year, if desired. However, we cannot guarantee any SEO benefits in return for your donation.

We appreciate all donations, but will not link/will remove links to any site we believe is harmful to visitors, offensive, or otherwise abusive.

If you pay taxes in the United States, your donation to ISC may be deductible from your federal taxes.

Internet Systems Consortium is a 501(c)3 corporation, EIN 20-0141248.

Please feel free to review our annual reports to see where your donations go.
