In addition to verifying the integrity of your zone data, the DNSSEC chain of trust can also be used to associate other information with your domain, such as PGP keys, to help improve the security of applications.

We have done quite a few of these profiles now, but fortunately we have not yet run out of staff members!

Computers are great, but sometimes it’s nice to go “old-school” with some handwritten messages.

BIND 9.20 is well established and stable. This is a good time to look at the performance of BIND 9.

ISC’s employees and board members are proud to participate in many governance bodies and community initiatives.

Most video recordings are also available on our YouTube channel. To be notified of upcoming webinars, follow ISC on Mastodon, LinkedIn, Facebook, or Bluesky, or subscribe to the training-info mailing list.

Last week, ICANN published a report on the importance of open source in the DNS.

It’s time to meet another of ISC’s engineers! This time, let’s get to know Włodek Wencel, our DHCP Quality Assurance Manager.

Is your DNS or DHCP implementation consistent with best practices? Find out with a configuration review from ISC.

Are you thinking of using ISC’s software? Sure, we think it’s great, but don’t just take our word for it; see why our existing customers and supporters use and support ISC’s software!

If you suspect you have found a vulnerability in BIND 9, Kea DHCP, Stork, or ISC DHCP, or if you wish to inquire about a vulnerability that you have learned about which has not yet been publicly announced, ISC encourages you to take one or more of the following actions, as appropriate:

One software vulnerability can enable a successful denial of service attack, disabling critical network services.

Protect your network, your data, and your business. Cyber criminals target software vulnerabilities.

Thank you for your interest! ISC has a long history of finding the best people to focus their talents and passions on the mission of supporting the infrastructure of the Internet.

ISC is excited to announce the release of Kea 3.0.0! This is a major release, and is the first Long-Term Support (LTS) version of Kea.

All of our staff profiles so far have been of our engineers, who are of course very important and make up the majority of ISC.

Fred Baker, ISC Board Member from 1994 – 2025

Stork 2.2 adds DNS support Since the last stable version of Stork we have begun adding support for monitoring DNS alongside DHCP.

Services provided by ISC are described expressly in a written Quote, which is subject to ISC terms and conditions of business.

A serious HTTPS vulnerability prompted us to check on the security of communications between Stork agents and the Stork server.

Hurrah! Twelve new open source hooks in Kea 2.7.7! With the release of Kea 2.

In the computer world, we commonly store temporary data in a cache to make programs run smoothly.

Piotrek Zadroga and I attended the DNS Hackathon, hosted by RIPE NCC, DNS-OARC and Netnod in Stockholm on March 14-15.

ISC has an OpenPGP key. OpenPGP is a public key system, which means that if you have our public key and we sign a mail message (or a software distribution) using our private key, you can have a reasonable confidence level that the message or distribution really did come from us.

If you think you may have found a security vulnerability in any ISC software, please take one or more of the following steps, as appropriate:

We’re back with another look at one of ISC’s staff members: Ben Scott!
