Terms of use
Service and permitted use
The site provides free network diagnostics, TCP port checks and approximate IP information. Use only your own servers, routers and services, or third-party systems with explicit owner permission, to investigate firewalls and port forwarding.
Prohibited uses
Unauthorized scanning of third-party networks, bulk automated requests, bypassing limits and illegal use are prohibited, including conduct covered by Brazil’s Marco Civil da Internet (Law 12.965/2014) and Carolina Dieckmann Law (Law 12.737/2012).
Warranties and liability
The service is provided as is. Results reflect the server’s perspective at test time and may be affected by firewalls, CGNAT, load balancers and external policies. We do not guarantee absolute accuracy or uninterrupted availability. We are not responsible for decisions based on results or direct or indirect damage arising from use or inability to use the service.
Advertising and changes
The site uses Google AdSense to fund operations, subject to approval. We are not responsible for third-party ad content. These terms may be updated at any time; continued use after changes constitutes acceptance of the new terms.
