01.What is DNS Cache and why clean it?
Windows keeps a list of sites you've visited (e.g., www.google.com -> 142.250.78.100) to load faster next time. If a site's IP changes or the cache file becomes corrupted, you'll see errors like 'DNS_PROBE_FINISHED_NXDOMAIN' or games that won't connect. 'FlushDNS' throws this list away and forces Windows to ask for the new path.

Executing 5 commands in CMD every time the internet drops is tedious. Voltris Optimizer has a 'Network Reset' button that executes the entire cleaning sequence (IP, DNS, Winsock, Proxy) and restarts the network adapter automatically.

02.Step 1: The Sacred Sequence (IP and DNS)
- Open CMD as Administrator.
- Release your current IP (disconnects internet momentarily):
ipconfig /release - Clear the DNS cache:
ipconfig /flushdns - Request a new IP from the router:
ipconfig /renew
03.Step 2: Resetting Winsock (Severe Errors)
If step 1 didn't solve it, there might be corruption in the Windows Socket (the API that software uses to access the network). This is common after removing viruses or uninstalling VPNs.
- In the same CMD, type:
netsh winsock reset - Reset the TCP/IP stack:
netsh int ip reset - RESTART YOUR COMPUTER. (Mandatory).
