Is my DNS hijacked?

You might have DNS hijacking if you see strange redirects, pop-ups, slow loading, or browser warnings about certificate errors; to check, use tools like Who is My DNS, try the ping test with a non-existent domain (e.g., ping randomsite12345.com), and examine your router's DNS settings for unfamiliar servers, as redirects and unfamiliar DNS servers are key signs of compromise, notes ThreatDown by Malwarebytes, ExpressVPN.
Is changing DNS to 8.8.8.8 safe?
Yes, Google's 8.8.8.8 DNS is generally considered safe, fast, and reliable, offering better security (like DNS over TLS/HTTPS) and privacy than many ISP defaults, though you trade your DNS queries to Google for enhanced performance and security, meaning Google sees your browsing habits for advertising/data collection. It's a trusted alternative, but be aware of the privacy trade-off, as it's not a magic bullet for all security issues like password breaches.
How to check if DNS is being used?

Is DNS spoofing still possible?
This is possible because DNS servers use UDP instead of TCP, and because currently there is no verification for DNS information. Instead of using TCP, which requires both communicating parties to perform a 'handshake' to initiate communication, DNS requests and responses use UDP, or the User Datagram Protocol.
