## Recommended Actions

For SOC Analysts:

1. Monitor Geographic Discrepancies: Track if the GB/LV geographic inconsistency persists. Investigate if related to legitimate mobile roaming or potential misuse.

2. Review DNSBL Status: One DNSBL listing detected. Verify if listing is active and assess source.

3. Baseline Behavior: Establish normal traffic patterns for this mobile endpoint. Given the no-services/firewalled profile, unexpected inbound connections warrant investigation.

4. Contextual Analysis: If this IP appears in security alerts, evaluate in context with associated mobile carrier Tele2 Sverige AB. Legitimate mobile traffic from this ASN may be expected.

5. No Immediate Blocking Recommended: Low risk score (25) and no known threat indicators support allowing traffic unless specific malicious activity is observed.
