When DNS records change, your device or browser may still use cached results. Clearing DNS cache helps fetch fresh DNS data.

Windows 10 / 11

1. Open Command Prompt as Administrator.
2. Run: ipconfig /flushdns
3. Alternatively (PowerShell): Clear-DnsClientCache

macOS (Big Sur, Monterey, Ventura, Sonoma)

1. Open Terminal.
2. Run: sudo dscacheutil -flushcache and then sudo killall -HUP mDNSResponder
3. Enter your password if prompted.

Linux

• systemd‑resolved: sudo resolvectl flush-caches (or sudo systemd-resolve --flush-caches)
• nscd: sudo service nscd restart (or sudo systemctl restart nscd)
• dnsmasq: sudo systemctl restart dnsmasq
• NetworkManager: sudo systemctl reload NetworkManager (or sudo systemctl restart NetworkManager)

Browsers

• Google Chrome / Microsoft Edge: open chrome://net-internals/#dns or edge://net-internals/#dns and click “Clear host cache”.
• Mozilla Firefox: open about:networking#dns and click “Clear DNS Cache”.
• Close and reopen the browser tabs after clearing.
