dnstracer

The dnstracer command determines where a DNS gets its information from. More information: https://manned.org/dnstracer.

• Find out where your local DNS got the information on www.example.com:
  dnstracer {{www.example.com}}
• Start with a [s]pecific DNS that you already know:
  dnstracer -s {{dns.example.org}} {{www.example.com}}
• Only query IPv4 servers:
  dnstracer -4 {{www.example.com}}
• Retry each request 5 times on failure:
  dnstracer -r {{5}} {{www.example.com}}
• Display all steps during execution:
  dnstracer -v {{www.example.com}}
• Display an [o]verview of all received answers after execution:
  dnstracer -o {{www.example.com}}
