DEEP DIVE

🔬 Root Cause: Why Does ERR_NAME_NOT_RESOLVED Occur?

When you type a domain (e.g. kravi.org), your system asks a DNS resolver for its numerical IP address. ERR_NAME_NOT_RESOLVED indicates that your configured DNS servers failed to return any valid A or AAAA records. This is usually caused by ISP DNS outages, local cache corruption, or malware tampering with the hosts file.

🔍 Primary Triggers for ERR_NAME_NOT_RESOLVED

ISP DNS servers experiencing outage or query drops.
Corrupted Windows DNS Client resolver cache.
Malware adding redirect entries to C:\Windows\System32\drivers\etc\hosts.
Conflicting VPN split-tunneling configurations.

⚠️ CRITICAL WARNING

What NOT to Do

Do not edit system hosts files without creating a backup first.
