摘要: Blocklists, consisting of known malicious IP addresses, can be used as a simple method to block traffic. However, blocklists potentially lead unjust blocking legitimate users due address reuse, where more could blocked than intended. addresses reused either at the same time (Network Address Translation) or over (dynamic addressing). We propose two new techniques identify addresses. built crawler using BitTorrent Distributed Hash Table detect NATed and use RIPE Atlas measurement logs dynamically allocated spaces. then analyze 151 publicly available IPv4 show implications find that 53-60% contain having about 30.6K-45.1K listings also affect many 78 for 44 days.
