Key takeaways
- Confirm the address is public and valid.
- Check network owner and ASN before applying broad rules.
- Document the reason for any block or allowlist decision.
Confirm the address type
A private or reserved address may indicate internal routing, logging behavior, or a data collection issue. Public addresses can be enriched with network and location context.
Review the network owner
ISP, organization, and ASN details can show whether traffic comes from a consumer network, cloud provider, company network, or infrastructure service. That context matters before applying security controls.
Document the decision
Support and security teams should capture the lookup result, risk level, and reason for action. A clear report helps future reviewers understand why the decision was made.
