Before you rely on a server or proxy IP, for example to log into your own US accounts while travelling, find out how the rest of the internet sees it. The questions are: what country and city do databases place it in, whether it's classed as hosting, ISP or mobile, whether it has a bad reputation, and whether your browser is leaking your real address anyway.
All the tools below are free for occasional manual checks as of September 2026. Their results come from commercial databases that update at different speeds, so compare two or three tools rather than trusting one.
Step 1: Type and location (ASN)
| Tool | What to look at |
|---|---|
| https://ipinfo.io | ASN / company type: isp, hosting, business or education. Also city and region, and privacy flags (VPN, proxy, hosting) on the web page |
https://ip-api.com (JSON: http://ip-api.com/json/?fields=66846719) | isp, org, as, and the booleans proxy, hosting and mobile |
| https://www.maxmind.com/en/geoip-demo | The geolocation that many banks and streaming services use |
What a "native" US residential IP looks like: the ASN belongs to a US consumer ISP (Comcast, Charter/Spectrum, AT&T, Verizon and so on), the type is isp, hosting is false, and the city matches across tools. A VPS from AWS, DigitalOcean or Vultr will show hosting, which is expected and fine for normal server use.
Step 2: Reputation and fraud score
| Tool | Score meaning |
|---|---|
| https://scamalytics.com/ip | Fraud score from 0 to 100. Under about 25 is low risk; above about 75 is likely to be blocked by many platforms. Also shows ISP and proxy classification |
| https://www.ipqualityscore.com/ip-reputation-check | Fraud score plus VPN, proxy, Tor and "recent abuse" flags |
| https://www.spamhaus.org/ip-reputation/ | Whether the IP is on spam blocklists (important for mail servers) |
A high score on a fresh VPS usually means the IP was abused by a previous customer. Most providers let you swap it for a new IP.
Step 3: Leaks and consistency (BrowserLeaks)
Open https://browserleaks.com in the browser you'll actually use:
- /ip: shows the IP the site sees. It should be your server or proxy IP.
- /webrtc: WebRTC can reveal your local or real IP even behind a proxy. If your real ISP IP shows up here, disable WebRTC leaks (browser setting or extension) or use a proxy mode that covers UDP.
- /dns: shows which DNS resolvers answered. If they belong to your home ISP in another country, you have a DNS leak.
- Timezone and language: sites compare your IP location with your system timezone and
Accept-Language. An IP in Los Angeles with a UTC+8 clock is a mismatch. That's normal if you are actually travelling, but be aware that it raises risk scores.
Cloudflare WARP: basics and limits
WARP is Cloudflare's free encrypted tunnel in the 1.1.1.1 app (Windows, macOS, Linux, iOS, Android), built on WireGuard/MASQUE.
- WARP encrypts traffic between your device and Cloudflare's nearest data centre, which is useful on untrusted Wi-Fi.
- It doesn't let you choose a country. Cloudflare says WARP gives you an IP that reflects your approximate real location and is not designed to bypass geo-restrictions.
- WARP+ (paid) only adds faster routing over Cloudflare's backbone. It still has no country selector.
- WARP exit IPs belong to Cloudflare's own network (AS13335). Reputation tools usually show them as hosting or VPN, and some sites add CAPTCHAs.
- Some server admins install WARP on a US VPS so that outgoing connections use a Cloudflare IP. Results vary by site and it may conflict with your provider's networking. Treat it as experimental.
Quick checklist
- ipinfo and ip-api agree on the country and city
- The type matches what you paid for (ISP vs hosting)
- Scamalytics / IPQS fraud score is low
- No WebRTC or DNS leak on BrowserLeaks
- Browser timezone and language are consistent with your situation
- Recheck monthly, because databases and IP reputations change
FAQ
Why do two tools show different cities? Each database has its own sources and update schedule. Small differences are normal. A different country is a red flag.
Can I "fix" a bad reputation score? Not quickly. Ask your provider for a different IP instead.
Does a good score guarantee access to streaming or fintech? No. Services also use device, payment and account signals, and their licences are region-specific.
