IP Reputation Check
Look up the reputation of any IP address, VPN, proxy, Tor, hosting and abuse signals combined into one clear picture.
Overview
What is IP reputation?
IP reputation is a summary of how trustworthy an IP address is, based on what it is and how it has behaved. An address that belongs to a VPN, proxy or hosting provider, or that has a history of abuse, carries more risk than a stable residential connection. An IP reputation check pulls these signals together so you can score an address quickly instead of investigating each factor by hand.
Signals
What goes into IP reputation
Reputation is the sum of several independent indicators.
Anonymiser signals
VPN, proxy and Tor association all lower reputation.
Hosting vs. residential
Datacenter origin is riskier than a consumer ISP.
Abuse history
Past spam, fraud or attack activity from the range.
Geolocation context
Location consistency across signals.
ASN ownership
Who owns the range and how it is typically used.
Combined risk score
A single 0–100 value summarising overall risk.
