Summary from the TLDR Dev newsletter

This website uses a custom traceroute program called ktr to visualize the journey of internet packets between the server and your IP address. The traceroute works by sending ICMP packets with increasing TTLs to map the routers and networks (autonomous systems) involved. These networks peer with each other using the Border Gateway Protocol to exchange routing information and determine the best path for data transmission.
