Welcome! This site is maintained by the Datomic team as an official place for the community to ask questions, request features, and get their problems solved.
Anyone may view the content on this site, but you must have an account to ask questions, provide answers or vote on questions/answers. Authentication is currently done using your GitHub account. Other authentication providers may be added in the future. When you have logged in, please click your user name in the upper right corner and review your profile. If you wish to receive email notifications, please add an email address.
Questions have both categories and tags. Categories (see right sidebar) are a fixed set of Datomic topics. At least a top level category must be selected when asking a question.
There are two special tags:
- problem - describe a problem or question you have
- request - describe a request for enhancement to Datomic
When problems or requests are logged, Datomic developers will assess and create corresponding internal issues for development.
Users may vote on both questions and answers. Votes can help surface the most helpful answers, and may be used to inform decisions about future releases of Datomic.
Welcome to ISC's Knowledgebase!
This site is intended to provide answers to many of the questions users may have about our open source software products: BIND 9, ISC DHCP, and Kea DHCP.
In this About ISC section, you'll find some general information that applies to all of our software. In the BIND 9, ISC DHCP, and Kea DHCP sections, you'll find lots of detailed information and helpful tips to make your network administration easier. Feel free to browse through everything, or use the search function to find articles on a specific topic of interest to you.
If you need more help than this Knowledgebase can provide, please consider joining one of our user mailing lists. These open fora offer best-effort support from other users of our software.
If mission-critical DNS and DHCP operations are important to you, we offer high-quality support from our team of experienced engineers as a paid service. Paid support contracts give ISC the funds we need to continue developing open source software that benefits the entire Internet. Please visit the Contact page on our main website for more details.
