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…

In order to expand the reach of F-root, one of the 13 root servers, we at ISC looked at where queries to our F-root servers are coming from and where it would make most sense to place new nodes. As a first step, we looked at the existing nodes to see how they behave and if there is anything we can …

When operators and researchers use data from BGP route collectors such as RIS and Route Views, it's not easy to tell if a path announced to a collector is an ISP's customer cone, an internal route, or one learned from peering or transit. In this post we look at what information we can currently get…
