Flush DNS Cache
Clearing cached records so Stripchat resolves with fresh data.
Definition
Flushing the DNS cache clears stored DNS entries on a device or resolver, forcing the next lookup to fetch new data from upstream servers.
Why it matters
- Removes poisoned entries: If an ISP injected bogus Stripchat IPs, flushing purges them.
- Applies configuration changes: After switching to a new resolver or editing hosts files, flush caches to avoid stale answers.
- Debugging: Distinguish between caching issues and live blocking.
Commands
- Windows:
ipconfig /flushdns - macOS:
sudo dscacheutil -flushcache && sudo killall -HUP mDNSResponder - Linux (systemd-resolved):
sudo resolvectl flush-caches
Also restart browsers or run sudo service nscd restart if using caching daemons.
