Blacklist results are reputation signals, not a full proxy health test. Use them with speed, location, and authentication checks before replacing a proxy list.
Proxy Blacklist Checker Guide
A proxy blacklist checker helps you find proxy IPs that appear in spam, abuse, open proxy, botnet, or attack databases before you use them for SEO, scraping, monitoring, advertising, account access, or browser automation workflows.
Default checks
The default scan uses widely known DNSBL sources so visitors can run a quick proxy reputation check without plugin-side key setup.
Optional checks
Optional DNSBL sources add more context through direct DNS lookups. Keep them unchecked when you want the fastest default scan.
Clean proxy workflow
After checking reputation, copy clean proxies, export all results, then test speed and location with the related BuyProxies tools.
Proxy Blacklist Checker FAQ
What does the proxy blacklist checker test?
The tool resolves each proxy host to a public IPv4 address and checks that IP against selected DNSBL, abuse, open proxy, and Tor exit databases.
Which databases are checked by default?
Spamhaus ZEN, SpamCop, Barracuda BRBL, DroneBL, and Blocklist.de are checked by default. Optional sources are visible but unchecked.
Are optional databases enabled automatically?
No. UCEPROTECT Level 1, SpamRATS, PSBL, Hostkarma, 0Spam, Mailspike, and Tor exit checks are unchecked by default and run only when selected.
Do optional sources require API keys?
No keys are stored in this plugin. Optional sources use DNS lookups or the public Tor exit list, while each provider can still enforce its own query policy.
Does the checker connect through my proxies?
No. This tool checks the proxy IP reputation only. It does not authenticate to the proxy or test proxy speed.
Can I copy only clean proxies?
Yes. After a scan, use the clean or listed copy buttons, or export all results as a CSV file.
