💖 adnsresfilter(1) 💖

okay bestie, so this is the adnsresfilter page from the adns manual — it's giving "asynchronous-capable DNS client utilities" energy and honestly? iconic. let's get into it ✨

✨ NAME ✨

adnsresfilter — Asynchronous-capable DNS client utilities 🦋

🌸 DESCRIPTION 🌸

first things first, the usage, no cap:

usage: adnsresfilter [<options ...>]

and also, for the times when you just wanna vibe-check it instead of actually running it:

adnsresfilter
  -h|--help | --version

then the options, which are literally the whole personality here:

  • -t<milliseconds>, --timeout <milliseconds> — sets your timeout, obviously 💅
  • -w, --wait — always wait for queries to time out or fail. like, it's not leaving the function early, it's staying until it's sure. main character energy fr
  • -b, --brackets — require [...] around IP addresses. square brackets or it doesn't count 🎀
  • -a, --address — always include [address] in output, no matter what
  • -u, --unchecked — do not forward map for checking. ma'am is skipping the vibe check 🙈
  • --config <text> — use this instead of resolv.conf. so if you wanna feed it config text directly instead of pointing at the file, this is your moment ⭐
  • --debug — turn on adns resolver debugging. it will be so chatty about what it's doing 🔥
okay so about the timeout, and this matters: Timeout is the maximum amount to delay any particular bit of output for. Lookups will go on in the background, so nothing is actually blocked while it waits — the timeout is just how long a specific piece of output is allowed to sit there being delayed. and the default is 1000 ms if you don't say otherwise 💜
