[Pdns-users] questions of understanding pdns-recursor with hosts-file

Hello Otto,

thanks for looking into this case. I thought, it could be the same behavior like "normal" hosts-files on clients/servers.
But no big deal, because you named good alternatives. Lua seems a little to complicated for me without prior knowledge from my side. I tried a rpz-Zone-file and everything works as expected, so this should be the fastest solution - thanks :)
One little question to rpz-files: is it legit to put more TLDs into this file or should I make separate files? Actually, I have more TLDs into this file and no problems, but I don't know, if this is to "dirty" ;)

Thanks and best regards,

Confirmed (the docs should be more explicit about this though).

I would suggest you look into Lua or RPZ zones. For Lua, see https://docs.powerdns.com/recursor/lua-scripting/index.html

With RPZ zones you can specify alternative replies based on the qname (but not the qtype) and they do not have the effect of covering everything below a qname.
