As QUIC gains attention, more applications that leverage its capabilities are emerging. These include defenses against on-path IP tracking and traffic analysis. However, the deployment of the underlying required support for connection migration remains largely unexplored. This paper provides a comprehensive examination of the support of the QUIC connection migration mechanism over the Internet. We perform Internet-wide scans revealing that despite a rapid evolution in the deployment of QUIC on web servers, some of the most popular destinations do not support connection migration yet.
