  • [Video] Silo Busting in Information Security – The SIE Approach

    Every few weeks a new security company is born. No matter what the brand or the segment, the data flow looks the same from on high: let’s get smart people and write some smart software, suck in all kinds of telemetry and samples, and produce threat feeds and reputation feeds, and then…profit! This plan works more often than not, due

  • Implementing Highly Memory-Efficient Zone Data in BIND 10

    Over the last several months, we’ve been working on improving (reducing) memory footprint of the BIND 10’s authoritative DNS server, b10-auth. The result is pretty satisfactory so far. According to my recent experiments, actual memory footprint after loading various types of zones is generally just a half of what would be needed in BIND 9. And, even if the BIND

  • Why We (Still) Need BIND 10

    Several years ago, ISC started the BIND 10 project. As part of the effort to kick-start the effort, Joao Damas and Paul Vixie wrote a paper called The Need for BIND 10. It’s been almost 4 years, and we have recently released the first BIND 10 alpha. It is worth asking, do we still need BIND 10? Open Source vs.

  • Introduction

    One of the things that I’m keen to get off the ground here at ISC is the measurement of quality. In the past few weeks since I’ve arrived, a lot of talk has been bandied about regarding quality, and specifically, improving it. Now, I’ve got some definite ideas about how to move towards that goal, and I know there is

In addition to being the first root-server operator to offer anycast instances in Africa, we have long provided Secondary Name Services (SNS) to a number of African ccTLDs as part of our public benefit mission.

  • A Word About Windows Binary BIND Distributions and OpenSSL Libraries

    At ISC we have recently received several inquiries from customers who are using the binary packages of BIND that we distribute for Microsoft Windows. They have expressed concerns about security vulnerabilities present in older versions of OpenSSL.  BIND uses OpenSSL for securing communications between dynamic nameservers and clients and between master servers and slave servers.  To support this functionality, ISC

  • BIND 9.9.0b2 — a feature update

    Today, ISC is publishing a new beta release of BIND 9.9.0.  As several new features have been added since the feature preview I posted on the occasion of the first alpha release, it would seem to be a good time for an update. Inline signing The new ‘inline-signing’ option, in combination with the ‘auto-dnssec’ option that was introduced in BIND 9.7,

  • Routing configuration over DHCPv6

    Currently the DHCPv6 protocol does not allow the provisioning of any routing-related information to hosts. A new proposal is addressing this shortcoming. The draft draft-ietf-mif-dhcpv6-route-option defines a mechanism for delivering routing information over the DHCPv6 protocol. This article explains core concepts and explains how to use the ISC DHCP software to deliver such information. A bit of history When the IPv6
