PowerDNS has delivered a proof of concept implementation of the exciting Catalog Zone work that is currently going on within the IETF DNSOP Working Group. To quote the draft specification:

DNS nameservers implement AXFR and IXFR for zone data synchronization among a zone's primary its and secondary nameservers, but the list of zones served by the primary (called a catalog in [RFC1035]) is not automatically synchronized. A method for automatic zone catalog provisioning and synchronization is useful, so that the zone catalog can be maintained in a reference location by an administrator, similar to zone data.

This document describes one such method, in which the catalog is represented as a regular DNS zone called a "catalog zone", and transferred using DNS zone transfers. The representation of catalogs within DNS zones is specified and nameserver requirements are listed so that DNS implementations can support catalog zones.

Our implementation can be found on GitHub, and it interoperates with the work recently also delivered in the BIND nameserver. As a part of the DNS community, we strive to deliver on the IETF motto of 'rough consensus and working code' so that once Catalog Zones become an actual RFC it is well tested and known to interoperate.

PowerDNS Founder Bert Hubert speaks at OX Summit, Oct 8-9, Berlin

The annual Open-Xchange Summit returns for its 7th year, with the most influential global Cloud and IT industry leaders and developers descending on Berlin, Germany's vibrant capital. With a program of informative keynotes, exciting product showcases, exhibitions, and exclusive networking, the conference takes place at the Café Moscow, just steps away from the city’s iconic TV tower.

“Trust in the cloud” is the cornerstone of the Summit agenda, with the past two years seeing concerns over privacy and security grow exponentially. The OX family continues to grow through offering secure, open source products and services that integrate easy-to-use encryption. Bert Hubert is top of the agenda presenting: “The Power of DNS to Engage more Customers". He will speak to this increasing interest of people searching for trusted Internet services and why 90% of all DNSSEC domains in Europe run PowerDNS.

Join us and over 500 decision-makers and technologists for this unique opportunity to lead the discussion on how the open and trusted Cloud ecosystem expands further.

Today in Rust, Germany – during the 11th annual WorldHostingDays – it was announced that Open-Xchange and PowerDNS have agreed to merge. This agreement will allow Open-Xchange to expand into important DNS product and support offerings, integrating DNS more deeply across their portfolio of open source messaging software. Meanwhile, by becoming part of a bigger family (which includes Dovecot), PowerDNS can focus on doing what it does best: developing and supporting great nameserver technologies.

Open-Xchange develops real-time communication and collaboration software that can run on existing cloud and telecom infrastructures. Deployed by the most trusted service providers worldwide, OX’s flagship product – OX App Suite – gives individuals the freedom to collaborate, work and communicate in the way they want to by combining document creation, email, messaging and calendar.

The combined company becomes the world’s leading provider of open source cloud software for ISPs, telcos and cable companies providing one point of contact for Internet-based services – from DNS, email backend to application frontend.

What makes this announcement so meaningful to us here at PowerDNS, is that in joining this family, we join great open source champions like Dovecot, which last week also became a part of OX.

We hope you agree that some things in life just get better and in joining the Open-Xchange family, it just did!

Bert Hubert CEO, Founder

Automated Coverity security scanning of PowerDNS Projects

PowerDNS values the security of the internet, and strives to keep its programs as secure as possible. To further this cause, we've run our code through the Coverity Development Testing suite, and as a result, we've been alerted to potential future security issues within our products. None of these issues were remotely exploitable, but nevertheless, in the future they might have been.

As an open source program, we were able to benefit from Coverity's Open Source Report, and since this report helped us improve our code, we've now integrated daily automatic Coverity scans of our products.

We are grateful to Coverity for this fine service, and we recommend their software and services to anybody that cares about security!
