Traceroute is a critical tool in the Internet measurement toolbox, but its output can be misleading. One problem for traceroute analysis is that certain types of Multiprotocol Label Switching (MPLS) tunnels hide routers from traceroute output. Worse still, there is no simple way to detect or reveal missing routers. Any analysis that expects comprehensive topology discovery—including identifying performance bottlenecks, analyzing traffic engineering approaches, and evaluating traffic sovereignty—needs to account for MPLS. In this paper, we replicate previous work by Vanaubel et al. [18, 21] to characterize and provide a snapshot of the current deployment of MPLS tunnels. We also release a sustainable and easily deployed tool for MPLS detection, called PyTNT. Using PyTNT, we find that the problematic types of MPLS tunnels remain prevalent, though we inferred a general decrease in MPLS usage across the Internet. We also inferred that public clouds accounted for 3 of the top 10 networks with the most routers observed to be in MPLS tunnels. Finally, we observed more MPLS routers in Europe than any in other continent, and more MPLS routers in the U.S. than any other country.
