ISP Name Analysis

Understanding how Internet Service Provider names are analyzed to detect VPN and proxy connections

What is ISP Name Analysis?

ISP Name Analysis is a fundamental technique used in VPN and proxy detection systems. It involves examining the Internet Service Provider (ISP) name associated with an IP address to identify patterns that indicate the use of VPN services, proxy servers, or other anonymizing tools.

When you connect to the internet, your IP address is associated with an ISP name that describes the organization providing the internet connection. VPN and proxy services often use distinctive ISP names that can be identified through pattern matching and analysis.

How ISP Name Analysis Works

Detection Process

  1. 1Extract ISP name from IP geolocation data
  2. 2Compare against known VPN/proxy provider databases
  3. 3Analyze for suspicious keywords and patterns
  4. 4Calculate confidence score based on matches

Common Indicators

  • VPN provider names (NordVPN, ExpressVPN, etc.)
  • Hosting provider keywords
  • Datacenter and cloud service names
  • Suspicious privacy-related terms

Limitations and Considerations

False Positives

Legitimate hosting services and datacenters may be flagged as VPNs, leading to false positives for users on business or cloud connections.

Evolving Landscape

VPN providers constantly change their infrastructure and ISP names, requiring regular updates to detection databases.

Residential VPNs

Some VPN services use residential IP addresses that appear as normal ISPs, making detection more challenging.

Best Practices for VPN Detection

•Combine ISP analysis with other detection methods for higher accuracy
•Regularly update VPN provider databases and patterns
•Use confidence scoring rather than binary detection
•Consider context and user behavior patterns
•Implement whitelisting for known legitimate services

Protect Your Privacy with Premium VPN Services

While ISP name analysis helps detect VPNs, using a high-quality VPN service with residential IPs and advanced obfuscation can help maintain your privacy and bypass detection systems.

Residential IP VPNs

VPN services that use residential IP addresses are harder to detect through ISP name analysis as they appear as regular home connections.
