Dear Colleague,

DNS and DHCP security are critical to the Internet Infrastructure. We appreciate your cooperation, assistance and initiative in informing us of the bugs you have found in our software. If you think you may be seeing a potential security vulnerability in BIND (for example, a crash with REQUIRE, INSIST, or ASSERT failure), please report it immediately either by selecting the pull-down to identify it as a security bug on the form below, or by emailing to and do not post it on the public mailing list.  If you have a crash, you may want to consult ‘What to do if your BIND or DHCP server has crashed.’

Community support via mailing-list

BIND, Kea and ISC DHCP are open source software. Community support is available on our public mailing lists: bind-usersdhcp-users, and kea-users.  We also provide expert professional support for our enterprise users via support subscriptions. You can reach our support team by filling out the form at

Reporting bugs for BIND

To report a bug or request a feature in BIND, please navigate to our Gitlab instance and enter your issue there. You will have the option of marking your issue confidential, if necessary. You will need to create an account on Gitlab, but you can link your credentials from another Gitlab instance or social media account. Once you have logged your issue, you may follow up via email. We don’t want to enable new issue creation via email because of the spam problem.

Reporting bugs in Kea

Kea has an open bug database at Please look and see if someone has already logged the bug you wish to report. You may be able to add information to an existing report, or to find a workaround or updated status on the issue that impacts you.  We also track feature requests in the issue tracker, so please submit feature requests there as well. Often it is helpful to first post these requirements on the kea-users mailing list to clarify whether there is already a way to accomplish what you need.

Due to a large ticket backlog and an even larger quantity of incoming spam, we are sometimes slow to respond, especially if a bug is cosmetic or if a feature request is vague or low priority.  However, we truly appreciate and depend on community-submitted bug reports and will address all reports of serious defects.

Thank you for your support!

ISC Team
