About:
dnstracer is a command-line utility that determines where a DNS domain is being served. It queries each nameserver in the chain of delegation from the root servers down to the authoritative nameservers, verifying that all servers are correctly configured and responding.

Key Features:

Traces the full delegation chain of DNS servers
Identifies misconfigured or non-responsive nameservers
Shows CNAME records and their final destinations
Provides color-coded output for easy analysis

Use Cases:

Debugging DNS propagation issues
Verifying DNS configuration across multiple nameservers
Identifying broken delegation chains

Alternatives:

dig – dig performs single DNS queries while dnstracer automates chain tracing
dnsquery – dnsquery is a Perl tool with similar functionality but different output format
