About this block

A /48 is the standard IPv6 allocation for a single site or customer, so the addresses inside it usually share one operator and purpose. Looking at a whole block shows whether a single suspicious address is an outlier or part of a pattern: a block where many addresses carry abuse reports, hosting infrastructure or anonymising services deserves more caution than one with a single flagged address.

Only addresses IPDebrief has analysed are listed. Each links to its full profile with ownership, routing, reverse DNS and risk evidence.
