## Risk Assessment

The IP maintains a high-risk classification (80/100) despite showing no active services or open ports. The geographic discrepancy between profile data (US) and historical signals (Sweden) requires investigation. The elevated risk score combined with DNSBL presence suggests prior abuse activity or reputation issues. Given the residential broadband context, this may represent a compromised endpoint rather than active infrastructure.
