What is IP quality?
Online shops, banks, streaming services and sign-up forms check the reputation of your IP address before they trust a visitor. Addresses that are shared by many people, belong to servers, or are used to hide identity get more CAPTCHAs, extra login checks and outright blocks.
"IP quality" describes how much your address looks like an ordinary home or mobile user. A clean residential IP has the fewest problems.
IP types explained
- Residential / ISP: an address from a consumer internet provider. Usually the most trusted type.
- Mobile: an address from a mobile carrier. Many users share each address, so sites rarely block them outright.
- Data center: an address from a cloud or hosting company such as AWS, Google Cloud or DigitalOcean. Normal for servers, unusual for people, so it is often flagged.
- VPN: an exit address of a VPN service, shared by many of its users.
- Tor: a public Tor exit node. Many sites block or challenge these addresses.
How to read the risk score
The score runs from 0 to 100: under 25 is low risk, 25 to 59 is medium and 60 or more is high. It is the sum of the factors listed under "Why this score?", such as Tor, VPN, proxy or data center networks, so you can always see where the number comes from. The How it works page lists the points for each factor.
The free data sources used here reliably recognise major cloud providers and Tor, and many mobile carriers. They miss residential proxies and small VPN providers, and cannot tell home from business broadband, so every type comes with a confidence level. A "Can't tell" flag means the data is not available, not that the answer is no.
What to do if your IP scores badly
- On a VPN and getting blocked: switch to another server, or turn the VPN off for that one site. A "VPN" result confirms the VPN works; it is not a fault.
- Home connection shows "Data center": check for an active proxy, a VPN browser extension or a corporate network. Some smaller providers are also misclassified by databases.
- Compare with mobile data: if your phone's mobile connection scores low risk, the problem is tied to your home address, not your device.
- Dynamic addresses change over time, and the score follows the new address. Restarting your router can give you a cleaner one.
