Understanding DNS Settings
DNS (Domain Name System) acts as the internet's phone book, translating human-readable domain names into IP addresses. Proper DNS configuration can improve your browsing speed, security, and reliability.
Security Note: Using reliable DNS providers can protect you from phishing attacks and malicious websites.
