Expanding the RIPE NCC Authoritative DNS Service means cooperating with the community to find organisations out there willing to host AuthDNS instances on their networks. In this article, find out exactly what's required from hosts and how to apply.
This is an experiment to see if we can increase the capacity and resiliency of the RIPE NCC's authoritative DNS service (AS197000). This service hosts all the reverse DNS zones, ripe.net and provides secondary service for various ccTLDs.
On Thursday 16 March 2017, at around 20:00 UTC, a bug in a script caused an outage for some reverse DNS delegations registered in the RIPE Database. The effects of the bug were not immediate, but began a cascading failure, that persisted until 18:00 UTC on Friday 17 March. In the following article,…
Rolling over the algorithm (usually to a stronger variant) used to sign a DNS zone isn't as easy as regular key roll-overs. This is because some DNSSEC validators are less forgiving than others, and fail validation unless the right combination of keys and signatures is present in a zone. This ar…
Some weeks ago, we installed a reply-size tester application at the global instances of K-root. We want to make this test available to more people, in an easy-to-use way. We have therefore written a Java application for this purpose.

The RIPE NCC is operating K-root, one of the 13 DNS root servers. In this article we shed some light on the operational policies of K-root to clarify possible misunderstandings about how it is operated.
We have redesigned the K-root architecture for our hosted nodes, formerly known as K-root local instances. System architecture and network setup have been simplified a lot. This will reduce our management effort for K-root and reduce costs for K-root hosts.
We did some measurements on the round-trip (RT) values of DNS queries for SOA (Start of Authority) records from our RIPE Atlas probes, over both UDP and TCP. We plotted the TCP/UDP ratios on graphs, and found that, as expected, for the majority of the measurements, it is around 2. However, we also …
