What Is DNS Cache?
Windows saves website name→IP lookups locally (the DNS cache) to speed up repeat visits. When a site changes servers or the cache corrupts, you get old/broken results — sites won't load while others work fine.
Hindi: DNS cache = Windows ka saved website addresses ka list. Purana ya corrupt ho toh sites nahi khulti — ipconfig /flushdns se saaf ho jata hai.
The Command — ipconfig /flushdns
- Win + S → type
cmd→ right-click → Run as administrator - Type:
```
ipconfig /flushdns
```
- Press Enter → "Successfully flushed the DNS Resolver Cache" ✅
Full Network Reset Combo
For deeper issues, run the full trio in order:
```cmd
ipconfig /release
ipconfig /flushdns
ipconfig /renew
```
/release— drops current IP/flushdns— clears DNS cache/renew— gets a fresh IP from router
What Flushing DNS Fixes
- ✅ "This site can't be reached" while other sites work
- ✅ Website moved servers but your PC still tries the old IP
- ✅ After changing DNS servers (8.8.8.8 etc.)
- ✅ Random browser loading glitches
What It Does NOT Fix
- ❌ No internet at all → router/WiFi issue
- ❌ Slow speed → bandwidth issue, not cache
- ❌ WiFi disconnected → adapter problem
