Due to operational malpractice or security attacks, an IP prefix (i.e., a block of IP addresses) can undergo many types of routing anomalies. Perhaps the most well-known of such anomalies is prefix hijacking, where an attacker hijacks traffic meant to reach the legitimate user of a prefix. Anomalies can also easily occur through route leaks, which can disrupt traffic for numerous prefixes at once. While various solutions have been proposed to detect such anomalies, these solutions are limited and susceptible to attacker countermeasures.
