Proxy Blacklist Checker
Paste a proxy list and check each resolved IP against every included DNSBL, spam, abuse, open proxy, and Tor exit reputation source by default.
Blacklist scan
Accepted formats: IP, host, host:port, host:port:user:pass, user:pass@host:port, http://host:port, socks5://user:pass@host:port.

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, Tor exit, or attack databases before you use them for SEO, scraping, monitoring, advertising, account access, or browser automation workflows. This page checks every included source by default so you get a broad proxy reputation report in one run.
All sources checked
Spamhaus, SpamCop, Barracuda, DroneBL, Blocklist.de, UCEPROTECT, SpamRATS, PSBL, Hostkarma, 0Spam, Mailspike, and Tor exit checks are selected in one category by default.
DNSBL reputation signals
DNSBL results can show spam reports, exploited hosts, poor reverse DNS patterns, open proxy listings, brute-force abuse, botnet indicators, and other IP reputation problems.
Clean proxy workflow
After checking reputation, copy clean proxies, export all results, then test speed and location with the related BuyProxies tools.
Bulk proxy checks
Paste up to 100 unique proxy lines per run. The checker accepts IPs, hostnames, host:port lists, user:pass formats, and URL-style HTTP or SOCKS proxy entries.
Result interpretation
A listed result means at least one selected source returned a hit. A warning means a source could not be queried or returned a response that needs review.
Proxy buying checks
Use blacklist checks before assigning proxies to long-running SEO tools, scraping jobs, browser sessions, or social media testing profiles.
Why proxy blacklist checks matter
Proxy IP reputation can affect deliverability, request success, account trust, search result access, crawler stability, and how often a target website challenges traffic. A proxy that works technically can still be a poor choice if its IP has recent abuse history or appears on multiple reputation lists.
For serious proxy work, blacklist status should be checked together with speed, uptime, IP location, ASN, authentication, and target-site behavior. That combination gives a clearer picture than relying on one single clean or listed label.
How to use the results
If an IP appears on one strict list, review the source and decide whether the use case is affected. If the same IP appears across several spam or abuse sources, keep it away from sensitive account, email, advertising, or scraping workflows. Use the clean copy button for quick handoff, or export CSV when you need a record for support or replacement requests.
The Tor exit result is an identity signal rather than a spam blacklist. Some projects intentionally use Tor-style routing, but most private proxy workflows should know when an IP is publicly recognized as a Tor exit.
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?
All included sources are checked by default: Spamhaus ZEN, SpamCop, Barracuda BRBL, DroneBL, Blocklist.de, UCEPROTECT Level 1, SpamRATS, PSBL, Hostkarma, 0Spam, Mailspike, and the Tor exit list.
Why are all sources in one category?
The checker treats every included provider as a blacklist or reputation source, so the page shows one source category and selects every source for a complete scan by default.
Do the blacklist sources require API keys?
No keys are stored in this plugin. The 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.
Can a clean blacklist result still be a bad proxy?
Yes. A clean blacklist result only means the IP was not listed by the checked sources at that moment. You should still test speed, authentication, uptime, location, and target-site compatibility.
Check blacklist status before blaming your software
If a proxy connects but the target blocks it quickly, reputation can be part of the problem. Blacklist checks are not perfect, but they are a useful signal before scaling a proxy pool.

Use it when
- Check whether a proxy IP appears on common reputation lists.
- Investigate repeated blocks or suspicious friction.
- Screen a sample before using a larger proxy batch.
Next checks
- Do not treat one blacklist as the whole story.
- Combine reputation checks with location and timeout tests.
- If many IPs fail, review the use case and request rate.

Proxy Blacklist Checker works best with reliable private proxies
After you test, format, locate, or inspect a proxy, move production work to a stable dedicated or semi-dedicated proxy plan.
