2. Verify Geolocation: Investigate discrepancies in inferred vs. claimed location.
3. Check DNSSEC: Confirm DNSSEC validity for subnets with multiple DNSBL listings.
4. Network Segmentation: Isolate residential traffic to mitigate risk from shared subnet abuse.
Note: While the IP itself shows no direct malicious activity, its network context and neighbors warrant closer scrutiny.
