What’s the difference between online testers and command-line tools?

Online versus command-line DNS tools:

Online testers:

Visual, user-friendly interfaces

Interpreted results with explanations

Often check from multiple locations

May cache results

Good for quick checks and sharing

Command-line tools:

Raw DNS data, no interpretation

Query specific servers

Real-time results

Scriptable for automation

Requires understanding of output format

Best practice: Use online tools for initial checks and sharing. Use command-line for troubleshooting and automation.

Pre-filled forms versus raw registry access. Different tools for different purposes.
