I forgot about this because I didn't focus much on the DNS server aspect of Pkarr.
But yes, because it commits to the DNS packet format, without much modifications you can use your dig or nslookup to learn more about a pubky, and all you need extra is the address of one DNS server that recognises Pkarr.
You want to know what homeserver a pubky uses, you make send an HTTPS question for the domain `_pubky.<the pubky>`
Not necessary for any app development but definitely handy for debugging
