Is This IP Address Safe?
When an unknown IP shows up in your logs, the goal is not just to identify it. The goal is to decide whether it is safe to allow, safe to challenge, or safe to block. That decision depends on reputation, attribution, and recent behavior.
FraudGuard turns those signals into clear risk context so you can make the call quickly.
A Simple Safety Checklist
- Reputation score: Is the IP associated with known abuse or threats?
- Threat classifications: Proxy, botnet, spam, or other malicious categories?
- Network attribution: Does the ASN or ISP have a history of abuse?
- Behavior patterns: Is this part of a broader pattern or isolated?
Fast Way to Check an IP
- Run a quick check with FraudGuard IP Lookup
- Review threat classifications and reputation in the IP reputation docs
- Expand to bulk lookup v3 if you need to evaluate ranges or many IPs at once.
- For large-scale enforcement, the Offline Threat Database provides a near real-time copy of ACE.
Turn Safety Into Action
Once you have the context, pick the response that fits your risk policy:
- Allow if reputation is clean and attribution is trusted.
- Challenge if signals are mixed or suspicious.
- Block if the IP is clearly associated with abuse.
Summary
“Safe” is not a guess. It is a decision based on reputation and context. FraudGuard gives you the risk signals you need to decide confidently and enforce quickly.
