Due to the increasing cost and decreasing availability of IP addresses, creating and maintaining large network telescopes has become difficult for universities. Institutions have sold many of the addresses they own or allocated them to devices using the internet.\u003C\/p\u003E\u003Cp\u003EDainotti will use his NSF grant to help universities and other organizations again have powerful network telescopes.\u003C\/p\u003E\u003Cp\u003E\u201cIf we stop seeing pollution coming from a particular area, maybe there\u2019s something wrong with connectivity there since that pollution is typically happening constantly,\u201d Dainotti said.\u003C\/p\u003E\u003Cp\u003EWhile universities might not have large numbers of inactive IP addresses to dedicate solely to a network telescope, many addresses aren\u2019t always in use. Until now, it has not been easy to track this activity. However, Dainotti has created a system to detect this automatically. Using this method, organizations can create what Dainotti calls a dynamic network telescope.\u003C\/p\u003E\u003Cp\u003EThe dynamic network telescopes also solve another problem: some malicious actors have learned how to detect and block the sets of IP addresses used in network telescopes.
