Residential Proxy Checker
Not every proxy sold as residential actually is. This checker classifies each exit IP as datacenter, residential, or mobile based on its network registration, and flags proxies that look like datacenter IPs being sold at a residential price. Paste your list and see the real type, ISP, and country of every proxy, so you know what you're actually paying for before you run a job on it.

Paste your proxy list and get instant health diagnostics, geo info, and anonymity detection.
| Status | Proxy | Protocol | Exit IP | Country | Type | ASN | ISP | Latency | Flags |
|---|
Target URL Proxy Check NEW
Test proxies against a specific target URL. Find out which ones actually work for scraping your target, not just which ones are alive. Detects WAF blocks (Cloudflare, DataDome, Akamai, Imperva, PerimeterX) and CAPTCHAs.
| Status | Proxy | Protocol | HTTP | Latency | Block Reason |

Port Scanner
Scan any host for open ports. Checks 22 common service ports by default, or specify your own.

Ping
Measure round-trip latency to any host. Returns min/avg/max and packet loss percentage.
My IP
See your public IP address, location, ISP, and whether you're detected as a proxy or datacenter.
IP Lookup
Look up geolocation, ISP, and metadata for any IP address.
Scrape Audit
Paste any URL to detect bot protection, CAPTCHA, JS rendering requirements, and get a scrapeability score.

Frequently asked questions
How do you detect a fake residential proxy?
We look up each live proxy's exit IP against its network registration (RDAP) and check whether it belongs to a hosting/datacenter provider or a consumer ISP. When a proxy sold as residential resolves to a known datacenter network, it gets flagged as suspected fake residential.
Why does it matter if a residential proxy is really datacenter?
Datacenter IPs are far easier for sites to detect and block. If you paid a residential price for stealth but got datacenter IPs, your success rate on protected targets will be much lower than expected, and you overpaid.
What's the difference between residential and mobile proxies?
Residential proxies use IPs assigned by home ISPs. Mobile proxies route through carrier networks (4G/5G) where many users share and rotate IPs, which makes them the hardest to block but usually the most expensive.
Can I check a whole residential proxy list at once?
The free tier checks 50 at a time. For a full provider list, a one-time $5 unlock covers up to 5,000, or the API handles recurring bulk validation with CSV export.
