What is the difference between a VPN, residential proxy, and ISP proxy?
Residential proxies route traffic through consumer devices and physical locations like homes and offices, while VPNs and ISP proxies are typically hosted in data centers. All three can present different network profiles.
Residential proxies route traffic through consumer devices and physical locations like homes and offices, while VPNs and ISP proxies are typically hosted in data centers. All three can present different network profiles.
VPN
- Routes traffic through a VPN provider's infrastructure.
- Often used for privacy, remote access, or location masking.
Residential Proxy
- Routes traffic through residential internet connections obtained through official and unofficial means, such as SDKs and bandwidth sharing agreements.
- Frequently used for web scraping, account creation, ad verification, and fraud operations.
ISP Proxy
- Uses IP addresses that appear residential but are hosted in data center environments.
- Often combines characteristics of residential and hosting infrastructure.
Similar questions
Are proxy SDKs primarily found in unofficial or malicious applications?
No. Proxy and bandwidth-sharing SDKs have been observed in both official app stores and less-official distribution channels. Their presence is not limited to free applications and may not always be clearly disclosed to users.
What should I do when I detect a VPN or proxy?
Detection alone should not automatically trigger a block. VPNs and proxies are used by both legitimate users and attackers. Most organizations incorporate VPN and proxy signals into broader risk-scoring or adaptive decisioning workflows that consider account history, geography, transaction context, and behavioral indicators.
What should an ISP, hoster, or ASN owner do if they discover residential proxy activity within their address space?
Organizations should investigate affected customers or devices, review acceptable-use policies, validate indicators, notify impacted parties when appropriate, and coordinate remediation efforts. Infrastructure owners are often in the best position to disrupt abuse occurring within their networks.
How quickly can Spur identify and classify newly discovered VPN or proxy infrastructure?
Spur continuously researches emerging infrastructure and updates classifications as new intelligence becomes available. New infrastructure is often identified and incorporated rapidly, allowing customers to benefit from current intelligence through the API and data products.
How does Spur detect VPNs, residential proxies, and ISP proxies?
Spur uses a combination of network intelligence, infrastructure analysis, behavioral signals, routing characteristics, historical observations, and proprietary research to identify and classify IP addresses. Multiple signals are evaluated together to determine the likelihood that an IP belongs to a VPN, residential proxy network, ISP proxy service, hosting provider, or other category.
