Hiya!
See https://stackoverflow.com/questions/43524492/nodemcu-udp-dns-request-format
Per this question, I've commented up the DNS server as-implemented so it's clear what RFC fields are set where in your code (in case someone ever wants to muck with them). I'm not sure whether nodemcu/lua will consume heap from the comments alone (no idea), so it may be worth either breaking out my comments into another file or stripping them as a preprocessing step when doing builds.
Happy holidays!
