PSBlackListChecker Overview
When to use PSBlackListChecker and what it covers.
Use PSBlackListChecker when you need a quick PowerShell view of whether one or more IP addresses appear on common DNS blocklists.
The module is useful during mail-flow troubleshooting, infrastructure reviews, or recurring monitoring checks where you want the results in PowerShell objects instead of a browser-only tool.
Common tasks
- Check a single IP address against configured DNS blocklists.
- Compare several addresses in one run.
- Return all checks, not only listed results, when you need a reviewable report.
- Sort output by IP address, blacklist name, or listed status.
