How to Use BrowserScan with IPWHOIS.io

BrowserScan is a powerful online privacy suite that tests browser fingerprints, DNS leaks, WebRTC leaks, and IP information. IPWHOIS.io complements it with an ultra-fast IP geolocation API that returns detailed network, security, currency, and timezone data—well beyond what BrowserScan’s built-in lookup shows. Pairing the two gives you deeper insight into your real-world privacy exposure and lets you cross-check IP details for VPN, proxy, or hosting indicators. This guide walks through why and how to combine them, along with practical workflows for manual and automated audits.

What Is BrowserScan?

BrowserScan is a no‑plugin toolkit that detects browser fingerprinting, IP leaks, DNS leaks, and WebRTC leaks. It scores your fingerprint’s authenticity, runs your IP through multiple third‑party geolocation sources, and offers extras like a port scanner, speed test, and bot detection. The tool is built for privacy‑conscious users, VPN testers, and security researchers who need a quick, all‑in‑one health check. If you’re comparing BrowserScan with similar tools, our BrowserScan vs BrowserLeaks vs IPhey article breaks down the differences.

What Is IPWHOIS.io?

How to Use BrowserScan with IPWHOIS.io product interface and feature overview.

IPWHOIS.io is a high‑performance IP intelligence REST API that delivers real‑time geolocation, connection metadata, timezone, currency, and security scoring for any IPv4 or IPv6 address. It runs on a proprietary Anycast network with 21 global points of presence, processes over a billion requests per day, and serves responses in JSON, XML, or CSV. The free tier allows 1,000 requests per day without registration, while paid plans add bulk lookups, threat detection, and an uptime SLA. Because it returns fields like security.proxy, security.vpn, security.tor, and connection.asn, it gives a richer IP context than a typical geolocation lookup.

Why Combine BrowserScan and IPWHOIS.io?

How to Use BrowserScan with IPWHOIS.io product interface and feature overview.

BrowserScan’s own IP lookup pulls data from sources like ip‑api, IPinfo, and IP2Location, but it typically shows country, city, ISP, and a basic blacklist status. IPWHOIS.io fills the gaps by providing:

• Threat detection flags – explicit proxy, VPN, Tor, and hosting indicators that are crucial for verifying whether a VPN is actually hiding your true IP.
• ASN and domain ownership – see which organization controls the IP block, often more telling than the ISP name alone.
• Currency and timezone details – useful when checking if geolocation-based services are working as intended.
• API‑driven automation – you can write scripts that run a BrowserScan check, extract the IP, and immediately enrich it with IPWHOIS.io’s threat intelligence, building a repeatable privacy audit pipeline.

Together, they help answer: “Is my VPN leaking my real IP? Does my IP appear as a known anonymizer? Is the geolocation consistent across independent data sources?”

Step-by-Step Workflow: Enriching BrowserScan Results with IPWHOIS.io

How to Use BrowserScan with IPWHOIS.io product interface and feature overview.

1. Run BrowserScan’s IP and Leak Tests

Visit BrowserScan and let the page run automatically. The IP section reveals your current public address, ISP, and approximate location. Note the IP address displayed; you’ll query it against IPWHOIS.io. Simultaneously, the DNS and WebRTC leak tests show whether your browser is exposing different addresses through alternative paths.

2. Send the IP to IPWHOIS.io’s API

Once you have the IP, you can query the free endpoint http://ipwho.is/{ip}. For example, using curl:

curl "http://ipwho.is/192.0.2.1"

The API returns a full JSON object with all available fields. You can also request specific data by using the fields parameter, e.g., ?fields=ip,country,city,security.proxy,security.vpn,connection.asn.

3. Parse the Response and Compare

Look at the security block to see if the IP is flagged as a proxy, VPN, Tor exit node, or hosting provider. Compare the country, city, and connection.isp fields with BrowserScan’s output. Discrepancies can indicate geolocation database differences or that a VPN is leaking a different region than expected.

4. Validate Against Your Expected Privacy Setup

If you are connected to a VPN, the IP should be that of the VPN server, not your ISP’s residential block. IPWHOIS.io’s security.vpn may not always return true for every VPN IP, but if hosting is true and the ASN belongs to a data‑center, it’s a strong signal you are indeed behind a VPN or proxy. If BrowserScan’s WebRTC leak test still shows your local IP, you have a leak regardless of what IPWHOIS.io confirms.

Practical Examples

Example 1: Verifying a VPN Connection

1. Connect to a commercial VPN and choose a server in Zurich, Switzerland.
2. Run BrowserScan; it shows an IP in Zurich with an ISP like “M247 Ltd.”
3. Query http://ipwho.is/ with that IP. The response shows:
   • country: "Switzerland", city: "Zurich" – location matches.
   • connection.asn: 9009, connection.org: "M247 Ltd" – confirms a data‑center operator.
   • security.hosting: true – the IP is indeed a hosting IP, not a residential one.
4. Because BrowserScan’s fingerprint test still reports a “masked” score and no WebRTC leak is found, you now have multi‑source evidence the VPN is working and no privacy‑breaking side‑channels are active.

Example 2: Investigating a Suspicious Proxy

After running BrowserScan on an unfamiliar network, the IP appears in a country you don’t recognize. You paste it into IPWHOIS.io’s live demo at ipwhois.io and immediately see security.proxy: true and connection.domain: "example.com" (a known anonymizer service). This confirms the network is routing traffic through a proxy—something BrowserScan’s basic blacklist may not have flagged explicitly.

Example 3: Automated Privacy Audit with a Script

You can build a lightweight script that opens BrowserScan (or simply extracts your current IP via a service call), then queries IPWHOIS.io and logs the results. Here’s a bare‑bones bash example:

# Fetch public IP from a simple echo service
PUBLIC_IP=$(curl -s https://api.ipify.org)

# Call IPWHOIS.io for geolocation and security data
RESPONSE=$(curl -s "http://ipwho.is/$PUBLIC_IP?fields=ip,country,city,security")

# Output key points
echo "IP: $(echo $RESPONSE | jq -r '.ip')"
echo "Location: $(echo $RESPONSE | jq -r '.city'), $(echo $RESPONSE | jq -r '.country')"
echo "VPN: $(echo $RESPONSE | jq -r '.security.vpn'), Proxy: $(echo $RESPONSE | jq -r '.security.proxy'), Tor: $(echo $RESPONSE | jq -r '.security.tor'), Hosting: $(echo $RESPONSE | jq -r '.security.hosting')"

Then run BrowserScan manually to verify that the IP reported matches the script’s output and that no WebRTC or DNS leaks expose a different address. Schedule this as a cron job to receive daily privacy snapshots.

When to Choose the Combined Approach Over BrowserScan Alone

BrowserScan’s built‑in IP tools are convenient, but the IPWHOIS.io combination is preferable when:

• You need explicit VPN/proxy/hosting flags, not just a blacklist pass/fail.
• You depend on high‑availability (IPWHOIS.io’s paid SLA guarantees 99.99% uptime) for continuous monitoring.
• You want currency, timezone, or native‑language data—useful for developers localizing content or verifying geo‑restrictions.
• You require bulk IP lookups to audit multiple endpoints at once (available through IPWHOIS.io’s Pro plan).
• You are automating the full privacy check cycle and need a stable, programmable API rather than screen‑scraping BrowserScan’s output.

If your goal is a one‑off manual browser privacy scan, BrowserScan alone is sufficient. But for systematic, enriched IP verification and threat detection, bringing in IPWHOIS.io significantly raises the depth of your audit.

Frequently Asked Questions

Can I use IPWHOIS.io’s free tier for personal privacy tests?

Absolutely. The free tier gives you 1,000 requests per day with no registration. For most individual privacy audits, that’s more than enough.

Does BrowserScan already use IPWHOIS.io data?

No. BrowserScan integrates with multiple geolocation providers, but IPWHOIS.io is not one of them. Using it externally adds an independent, threat‑aware data source to your verification stack.

Is it safe to send my IP address to IPWHOIS.io?

The API supports HTTPS, and the service only processes the IP for lookup purposes. However, like any service, you should review their privacy policy if you have strict data‑handling requirements.

What if BrowserScan and IPWHOIS.io show different locations for the same IP?

Geolocation databases differ in accuracy and update frequency. A discrepancy doesn’t necessarily mean a leak; it often reflects different data sets. Cross‑reference with other sources or check the IP’s ASN and hosting status to form a holistic picture.

How can I integrate this workflow into a larger site or app?

You can embed BrowserScan’s fingerprint testing via its public web interface (or an iframe) and simultaneously call IPWHOIS.io’s API from your backend. Just remember to respect rate limits and handle user IPs responsibly under your privacy policy.

A Stronger Privacy Audit with Two Specialized Tools

BrowserScan excels at detecting browser‑level leaks and fingerprinting risks. IPWHOIS.io adds deep IP intelligence and threat detection that goes far beyond a basic geolocation lookup. Together, they form a cross‑referenced verification system—manual or automated—that helps you confirm whether your connection really is private, your VPN is tight, and your IP isn’t leaving unintended footprints. At BrowserScan, we’ve tested dozens of privacy tools, and this pairing consistently delivers the kind of layered insight that a single service alone cannot match.
