Why is my IP detected as a VPN or flagged as a proxy?A proxy or VPN flag doesn't mean you got the wrong product. IP checkers look at registration, observed use, and reputation, so a residential IP can still be flagged as a proxy. Check what each label actually measures, and contact your provider only if registration results consistently contradict the product you bought.Proxy 101
Common proxy ports explained (8080, 3128, 1080)A proxy port is where your app connects to the proxy server, while the destination port is where the website accepts the request. Common proxy ports like 8080 (HTTP), 3128 (Squid), and 1080 (SOCKS) are conventions, not requirements. Always use the host, port, and protocol your provider assigns.Proxy 101
Why does my IP show the wrong location?IP addresses don't contain coordinates, so websites rely on geolocation databases that estimate location and can be outdated or disagree. A wrong location can also come from a VPN, proxy, or other signals like account settings. Compare a few lookup tools, then submit corrections to the databases that show the wrong result.Proxy 101
How to check if an IP is residential: the 5 signals to testAn IP checker's "residential" label is a clue, not proof. To test it, check five signals on your proxy's exit IP: the announcing ASN, reverse DNS, published cloud ranges, the RIR registration record, and vendor usage-type labels. Together they show whether the IP is tied to a consumer ISP or a hosting network, though none can confirm the exact device behind it.Proxy 101
Why is My Proxy Not Working? When a proxy fails, check four places in order: your connection and app, your proxy login, your plan limits, and the target website. A quick curl test and the error code you get usually show which layer is causing the problem. If you're still stuck, contact support with the exact error and request details.Proxy 101
Mobile Proxies VS Residential ProxiesMobile proxies use carrier networks, rotating residential proxies use home internet connections, and static residential (ISP) proxies use consumer-ISP addresses on datacenter hardware. Choose mobile for carrier IPs, rotating residential for large location-based pools, and static ISP when you need to keep one address. Test a small sample on your target sites before scaling up.Proxy 101
What is a native IP address?A native IP is an IP address whose registry allocation, routing origin, and geolocation records all match the country the provider claims. You can verify it by checking the IP in an RIR lookup, a BGP/ASN tool, and several geolocation databases. Matching records mean the country label is likely accurate.Proxies & Business
ISP vs datacenter proxies: key differences and when to use eachA quick guide to ISP and datacenter proxies: both run on data center servers, but they differ in where the IP comes from. Datacenter proxies suit fast, low-cost public data collection, and ISP proxies suit long sessions and account work.
