You do not need to run your own validation software, just plug your RPKI-enabled router to GoRTR and start filtering. By default, it will fetch the list of prefixes available at /rpki.json. We made sure that it could be used with various servers and implemented cryptographic checks to ensure an untampered distribution. We created GoRTR, a small Go application which will fetch a JSON file using a format used by RPKI Validators. Ideally using our CDN for caching the resources. OctoRPKI and GoRTR ecosystem diagram GoRTRĪs our network keeps growing, we needed a scalable solution to send the list of validated ROAs to our edge. There are two components: GoRTR and OctoRPKI. We emailed Network Operating Centers and were happy to see the records got corrected in a matter of days. We noticed many important networks announcing invalids on Internet Exchange Points. It is worth mentioning that one provider experienced a substantial traffic shift due to many regional IPs announced as smaller subnets and not included in the Route Origin Attestation (ROA), a key resource of the RPKI environment. At our scale, it is a drop in the ocean of packets. The spread remains high due to the difficulty of accounting the traffic that would go towards an invalid route.
We received many questions regarding the amount of invalid traffic. The deployment amounts to around 70% of our network.

This means a user browsing the websites on Cloudflare’s network are unlikely to experience route hijacks.Īll our Points of Presence which have a router compatible with The Resource Public Key Infrastructure (RPKI) to Router Protocol (RTR protocol) are connected to our custom software called GoRTR and are now filtering invalid routes. This means, as a 1.1.1.1 DNS resolver user, you are less likely to be victim of cache poisoning. Picture TLS certificates for IP addresses and Autonomous System Numbers (ASNs) What it means for you: As a brief reminder, RPKI is a framework that allows networks to deploy route filtering using cryptography-validated information. Today’s article is going to cover our experience and the tools we are using. We want to make it easier for network operators to deploy RPKI. Our mission is to build a safer Internet. A few months ago, we made a first then a second announcement about Cloudflare’s involvement in Resource Public Key Infrastructure (RPKI), and our desire to make BGP Internet routing more secure.
