IPTOOLBOX / INFORMATION
Use the Results with Context.
Educational utilities, not proof that an address, DNS record or network plan is suitable for a production change.
Verify Before Applying
Check important results independently. Address math does not prove ownership, reachability, allocation or permission. DNS responses reflect recursive resolver views at the time of the query. Transfer estimates depend on the assumptions you enter.
Respect Shared Resources
The active HTTP allowance is 60 requests per source IP in any rolling 60 seconds. The secondary DNS budget is 30 lookup units per minute; a comparison uses two. Do not overload the service, bypass its limits or use it to facilitate abuse. People sharing a public IP share its allowance.
Availability and External Services
The tools and free endpoints have no uptime commitment. Features and external providers can change or become unavailable. Linked products, services and references are operated separately; review their terms directly.
Responsible Reports
Send minimal non-sensitive examples. Do not send passwords, credentials or private customer records.
Questions, corrections, privacy requests, or advertising enquiries: [email protected]. Please do not send passwords, credentials, customer records, or a complete production address plan.
