Built-in Measurements
Whenever a host connects a RIPE Atlas probe, it automatically starts executing a set of pre-defined measurements. In our terminology these are called "built-in measurements". The probe's network capabilities determine if these measurements are scheduled over IPv4, IPv6 or both.
The set of built-in measurements contain ping, traceroute, DNS, SSL/TLS and some HTTP types, mostly towards well-known targets such as DNS root servers, but also towards some of the RIPE Atlas infrastructure components.
This page describes what measurements are scheduled, and how you can access the results of these.
Accessing the Results
The host of a particular probe can access the results of built-in measurements of their own probe(s) via the Built-in Measurements tab on the probe status page. One can find a Log Downloads section at the bottom of the page.
The same data is also accessible via the "result" section of the measurement REST API as well as the streaming API.
List of Built-In Measurements
The following table lists built-in measurements and their unique measurement ID, ordered by measurement type.
