Abstract:Anycast, a crucial component of the Internet, enables the sharing of a single IP address among geographically distributed servers, playing a vital role in providing essential services such as the Domain Name System (DNS). The wide adoption of anycast can be attributed to its significant benefits, particularly improved resilience. To better understand the resilience of these essential Internet services, efforts have been made to develop measuring tools capable of performing anycast censuses. One of these, MAnycast, uses an innovative approach in which an anycast network is used to perform a census of other anycast networks. While its results were promising, the initial version of MAnycast had limitations. This work improves the MAnycast measuring system, with the focus on facilitating more accurate anycast censuses. The main contributions of the new system include synchronous probing, support for TCP and UDP probing, improved resource efficiency, and service-specific DNS probing. Through multiple MAnycast measurements that validate our approach, we demonstrate that these contributions significantly enhance scalability, coverage, and accuracy in performing anycast censuses.
