Roots of the world tree: RIPE NCC security labs

The RIPE NCC Academy security labs let one study the hidden roots, where rot, stress, and intrusion can quietly take hold, and learn how to keep the tree standing strong against the storms that test it. The exercises are built around real internet infrastructure and measurement systems: routing, switching, packet analysis, IPv6 addressing. They map well to the BGP and IP sections in Rootways and to the network reconnaissance runbook in Tradecraft.
