What are VPN and datacenter IP addresses?

Most residential internet connections use IP addresses assigned by consumer internet service providers, tied to a home or mobile network. VPN and datacenter IP addresses are different - they belong to commercial hosting providers, cloud platforms, and VPN services rather than everyday households. Traffic coming from these addresses often indicates that a visitor is using a VPN to mask their real location, or that a request is coming from an automated server rather than a real person browsing at home.

Many websites check whether an incoming IP address belongs to a known VPN or datacenter range as a signal for fraud prevention, bot detection, or enforcing geographic restrictions, since these connections are frequently used to bypass such controls.

Tool description

VPN & Datacenter IP Checker looks up an IPv4 or IPv6 address against known lists of VPN providers and datacenter network ranges. Enter an address to instantly see whether it's associated with a VPN, a datacenter, both, or neither, along with the date the underlying lists were last updated.

Features

  • Combined VPN and datacenter detection - checks against both categories in a single lookup
  • IPv4 and IPv6 support - works with both address families
  • List freshness indicator - shows when the underlying detection lists were last updated

Options explained

Field Description
IP address The IPv4 or IPv6 address to check.
Result Indicates whether the address is clean, a VPN, a datacenter, or both.
Lists updated at The date the VPN/datacenter reference lists used for the check were last refreshed.

Limitations

  • Detection relies on maintained lists of known VPN and datacenter ranges, which may not cover every provider or may lag behind newly allocated ranges.
  • A "clean" result means the address wasn't found in the current lists - it doesn't guarantee the connection isn't a VPN or proxy from an unlisted provider.
