Find answers to common questions about our IP lookup service.
An IP address lookup is a service that provides information about a specific IP address, including its geographic location, network details, and security status. Our tool shows you the country, region, city, ISP, organization, and whether the IP is listed on any spam blacklists.
IP geolocation accuracy varies depending on the type of connection and location. Generally:
The data is more accurate for residential connections and less precise for mobile or satellite connections.
Yes, our IP lookup service is completely free to use. There are no hidden fees, registration requirements, or premium features. We maintain the service through fair usage policies with rate limiting to ensure availability for all users.
RBL (Real-time Blackhole List) checks determine if an IP address is listed on spam or malware blacklists. These checks are important for:
We check against 10 major RBL providers including Spamhaus, SpamCop, and SORBS.
Rate limiting ensures fair usage and service availability for all users. Our limits are:
If you exceed these limits, you'll need to wait before making additional requests. For higher volume needs, please contact us about API access.

IP geolocation is not always 100% accurate due to how IP addresses are allocated and routed. Factors affecting accuracy include:
The data comes from our trusted providers and represents the best available information.
We're currently developing API access for developers and businesses. Visit our API documentation page for updates and to express interest in early access to our programmatic interface.
Our data sources update their information regularly:
We cache RBL results for 6 hours to balance freshness with performance.
