Changed your proxy, but the website still sees your old IP?
In this video, we break down how DNS cache works at the browser and system levels, why it disrupts proxy logic, and leads to incorrect GEO, captchas, and bans

Step-by-step, we cover:
- What DNS cache is and where it’s stored (browser, OS, network stack)
- Why requests may still go to old IPs after switching proxies
- How DNS can bypass proxies and where leaks occur
- How to properly clear DNS cache in Chrome, Edge, Firefox, and at the system level
- When clearing cache doesn’t help and the issue runs deeper (CDN, app cache, proxy configuration)
We’ll also show practical steps: how to check your real IP, make sure traffic is going through the correct proxy, and configure your environment so the browser doesn’t “do its own thing.”
