# 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 IPv[4] servers:
|
|
|
|
`dnstracer -4 {{www.example.com}}`
|
|
|
|
- [r]etry 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}}`
