How to choose the right networking tools
Investigate public DNS, IP, HTTP, TLS, performance, accessibility, and loading behaviour for development and troubleshooting.
Before you use a tool
- Use a public hostname or IP address you are authorized to inspect.
- Interpret one lookup as a point-in-time observation.
- Use the right tool for the job: PTR for reverse DNS, DNS lookup for records, and HTTP tools for response headers.
A practical workflow
Start with DNS or IP information, inspect the relevant response, compare it with expected configuration, and retest after propagation or deployment changes.
