  • Who Pays for ISC’s Open Source?

    ISC’s open source, including BIND, ISC DHCP and Kea, is sustained by software support contracts. Open source software is free for the user, but developing it does cost money.  Our software systems are large and complex: the developers are doing a professional job like any other software development job.  Most of the money to support these projects comes from revenues from software

  • Why you want a root server nearby, even if you have to host it yourself

    There are three reasons why you want a root server near you: Performance (faster response time) Resilience (less affected by global infrastructure problems) Privacy (less opportunity for eavesdropping) Introduction In the early days of the internet, most international traffic passed through the USA. Traffic between two nodes in Japan that didn’t use the same ISP was often routed through San Francisco.

  • ISC DHCP moves to MPL 2.0 license

    We have decided to move ISC DHCP to the Mozilla Public License (MPL 2.0). In 2016 we re-licensed BIND and Kea under the Mozilla Public License 2.0.  At the time we solicited public comment, and talked to many stakeholders about it. In the end, we didn’t see any negative impact on our users from that change.  Now we plan to make the same shift from

    Over the past five years, we have taken on average, 32 days to publicly disclose a BIND vulnerability, from the time we receive the first report.   Typical steps from report to disclosure include: Set-up secure email link with reporter, request more details Reproduce in house (this can take a while, particularly if the reporter can’t provide enough detail) Team

  • I/O Efficient GZip Compression of Packet Captures

    One of the major challenges with logging network traffic is that it is very disk I/O intensive. It can also require a lot of storage. The storage requirements often lead to the use of file compression algorithms such as gzip to reduce the amount of disk space needed. For DNS traffic this can typically result in an 80% reduction in

  • Funding Kea

    Kea 1.2.0 was released a couple of days ago. You may have noticed that there are two new premium features available. We have received some questions. Is Kea becoming commercial? No. Kea is and will remain open source. Fears that Kea is becoming a commercial product are simply not true. Our first commercial add-on – the Kea Forensic Logging library –

    “ISC is dedicated to developing software and offering services in support of the Internet infrastructure.” Once a year, we attempt to catalog what we did the prior year towards supporting the infrastructure.  We do have a small team who are very busy keeping F Root going, as well as the hosting services we still provide for some non-profits, but they are too busy
