IP2Proxy .NET Component

This component allows user to query an IP address if it was being used as VPN anonymizer, open proxies, web proxies, Tor exits, data center, web hosting (DCH) range, search engine robots (SES) and residential (RES). It lookup the proxy IP address from IP2Proxy BIN Data file. This data file can be downloaded at

As an alternative, this component can also call the IP2Proxy Web Service. This requires an API key. If you don't have an existing API key, you can subscribe for one at the below:



Microsoft .NET 4.72 framework or later. Compatible with .NET Core 2.x/3.x SDK. Compatible with .NET 5/6.



Below are the methods supported in this class.

Method Name Description
Open Open the IP2Proxy BIN data for lookup. Please see the Usage section of the 2 modes supported to load the BIN data file.
Close Close and clean up the file pointer.
GetPackageVersion Get the package version (1 to 11 for PX1 to PX11 respectively).
GetModuleVersion Get the module version.
GetDatabaseVersion Get the database version.
IsProxy Check whether if an IP address was a proxy. Returned value:<ul><li>-1 : errors</li><li>0 : not a proxy</li><li>1 : a proxy</li><li>2 : a data center IP address or search engine robot</li></ul>
GetAll Return the proxy information in an object.
GetProxyType Return the proxy type. Please visit <a href="https://www.ip2location.com/database/px10-ip-proxytype-country-region-city-isp-domain-usagetype-asn-lastseen-threat-residential" target="_blank">IP2Location</a> for the list of proxy types supported
GetCountryShort Return the ISO3166-1 country code (2-digits) of the proxy.
GetCountryLong Return the ISO3166-1 country name of the proxy.
GetRegion Return the ISO3166-2 region name of the proxy. Please visit <a href="https://www.ip2location.com/free/iso3166-2" target="_blank">ISO3166-2 Subdivision Code</a> for the information of ISO3166-2 supported
GetCity Return the city name of the proxy.
GetISP Return the ISP name of the proxy.
GetDomain Return the domain name of the proxy.
GetUsageType Return the usage type classification of the proxy. Please visit <a href="https://www.ip2location.com/database/px10-ip-proxytype-country-region-city-isp-domain-usagetype-asn-lastseen-threat-residential" target="_blank">IP2Location</a> for the list of usage types supported.
GetASN Return the autonomous system number of the proxy.
GetAS Return the autonomous system name of the proxy.
GetLastSeen Return the number of days that the proxy was last seen.
GetThreat Return the threat type of the proxy.
GetProvider Return the provider of the proxy.


Open and read IP2Proxy binary database. There are 2 modes:

  1. IOModes.IP2PROXY_FILE_IO - File I/O reading. Slower lookup, but low resource consuming. This is the default.
  2. IOModes.IP2PROXY_MEMORY_MAPPED - Stores whole IP2Proxy database into a memory-mapped file. Extremely resources consuming. Do not use this mode if your system do not have enough memory.
