Some of our satisfied support customers

  • SIDN

    SIDN operates the .nl country registry for the Netherlands, the first active country top-level-domain in the DNS, outside of the US. SIDN Labs authors tools and conducts research projects to help support the Internet and DNS in particular. As an ISC support customer, SIDN is also helping to support the open source you use!

  • NZRS

    NZRS operates the registry for .nz. They offer internationalized domain names in the Māori language, both under a separate third-level domain and in .nz. NZRS engineers are frequent participants in DNS-OARC conferences. Sebastian Castro of NZRS personally contributed to the development of BIND's dnssec key-manager utility. NZRS subscribes to ISC's Advance Security Notifications for BIND.
  • SWITCH

    Switch operate the Swiss country-code TLDs, .ch and .li.  Switch subscribe to ISC's Advance Security Notification service, so they can receive BIND patches for critical security issues a few days before they are announced.   Switch use BIND resolvers and dnsdist to provide recursive DNS services to users of the Swiss higher education and research network NREN.  Switch also offer a DNS Firewall service which supports BIND with RPZ.  Oli Schacher of Switch discovered and reported a serious bug in RPZ, which ISC fixed in CVE 2017-3140.   Switch not only supports ISC with a regular ASN contract, they also made an unrestricted donation of CHF 10,000 to ISC in 2017.  
  • CIRA

    CIRA is the Canadian Internet Registry Authority. CIRA also now provides a DNS Anycast service and a DNS security service for enterprises. CIRA has supported ISC for many years: they were one of the Patron supporters of ISC's BIND 10 project, which lives on in the Kea DHCP server, and they have made many advances in the DNS community, particularly in operationalizing DNS security (DNSSEC).  CIRA contribute actively to the DNS technical community through DNS-OARC, as you can see from this recent presentation from Evan Thompson on the Provisioning Performance of Name Server Software. Through their support relationship with ISC, CIRA is helping to underwrite the maintenance of ISC's open source for everyone.

Selecting a SW Version

The planned EOL date for every release is noted on the software downloads page, and our software support policy is documented here. If you have just taken over an existing BIND or DHCP installation, you might want to check our list of published security vulnerabilities to ensure your implementation is not vulnerable.

BIND Documentation

BIND Documentation consists of the Administrators Reference Manual (ARM), and a Doxygen doc included in the source code.

 

DHCP Documentation

Kea is well-documented, with both user and developer documentation published at kea.isc.org.

ISC DHCP is distributed with man pages that are available on-line in the installed product. There are also short feature descriptions and tips in the ISC Knowledgebase.

Knowledgebase

Our online Knowledgebase features short articles on our software and answers many frequently asked questions. We also publish a page of links with community-provided How-to’s, free software tools, and information on the most useful published books.

Community Support

BIND, Kea and ISC DHCP are open source software. Community support is available on our public mailing lists: bind-usersdhcp-users and Kea-users. Mail-archive.com, which is not affiliated with ISC, hosts searchable archives of bind-users and dhcp-users if you want to look and see if your question has already been asked and answered on the list. We recommend that all BIND 9 users subscribe to the bind-announce mailing list, to receive notices of any security vulnerabilities, as well as notices of new versions available. For DHCP users the equivalent list is dhcp-announce and for Kea it is Kea-announce.

Reporting Bugs, Requesting Features

Everyone can help contribute to open source quality by submitting complete and accurate bug reports. To report a bug, please check which product you are using as BIND 9, ISC DHCP, and Kea DHCP each use a different issue tracking system.

For BIND 9 issues or feature requests, please open an issue at gitlab.isc.org.

BIND 9 security is critical to the Internet infrastructure. If you think you may be seeing a potential security vulnerability in BIND 9 (for example, a crash with REQUIRE, INSIST, or ASSERT failure), please report it immediately to security-officer@isc.org and do not post it on the public mailing list.

Please send ISC DHCP issues to dhcp-bugs@isc.org, and mail feature requests to dhcp-suggest@isc.org.

For Kea DHCP issues, please open an issue at the Kea gitlab site or raise the question on kea-users@lists.isc.org.
