Based on 844 announced prefixes, updated daily (2026-10-26). How the score works ยท RPKI explained
Listed on the threat map (2026-10-26)
- #8 of the 50 networks with the most flagged IPs worldwide (227 flagged networks)
- #3 in the United States (227 flagged networks located there)
- #6 for brute force sources (178 flagged networks)
- #8 for spam sources (17 flagged networks)
Large hosting providers appear because attackers rent their servers, not necessarily because of the operator.
