DNS caching is when your device or browser temporarily stores DNS lookup information — basically, it remembers a domain’s IP address. Instead of asking the DNS server every time you visit a website, your device uses the cached data to connect faster.

Why it matters?
• Speed: Cached DNS results load sites much quicker because they skip the lookup process.
• Reduced Server Load: Fewer DNS requests mean less traffic for DNS servers, making the web faster overall.
• Better User Experience: Faster website access = happier visitors!

But be careful
• If a site changes its IP or DNS settings and your cache is outdated, you might get errors.
• Sometimes clearing your DNS cache (called a "flush") is necessary to fix issues like site not loading properly after a move or update.

Quick Tip:

To flush your DNS, you can run ipconfig /flushdns (Windows) or sudo dscacheutil -flushcache (Mac).

Proper DNS caching boosts performance — but knowing when to clear it helps avoid frustrating problems!

From my experience I want to share this details..

Using a private DNS resolver (like Google DNS or Cloudflare) often leads to faster DNS resolution since they have high-performance servers and smart caching mechanisms.

Also, DNS caching can delay the propagation of DNS changes. If you update your DNS records, it can take up to 48 hours for all caches to update, depending on TTL.....
