Frequently Asked Questions
▶ Is this service free?
Yes, this is a free tool for the community. Please respect the fair usage policy to keep it available for everyone.
▶ How do I use this in scripts?
Use
curl ipsearch.uk
for a plain text IP or append
/json
for detailed metadata.
▶ Does this detect VPNs?
Yes. We use the IP2Location LITE database specifically for proxy detection, combined with a manual analysis of ASN providers to catch unlisted datacenters.
▶ Reputation Scan details?
We aggregate real-time threat data from CrowdSec, FireHOL, GreenSnow, and major DNSBLs like SpamCop to detect active attackers.
▶ Data Privacy
No logs are kept. This service runs entirely in memory to ensure privacy and security.
▶ Are there Rate Limits?
To ensure stability, we limit requests to 100 per 5 minutes per IP address. Exceeding this will result in a 429 HTTP error.
▶ How accurate is the data?
We combine MaxMind GeoLite2 for location/ISP data with IP2Location for threat intelligence. Both databases are updated regularly.
▶ Why two IP addresses?
Modern networks often support both IPv4 and IPv6. We intelligently detect and display both if your connection supports them.
