ANY queries don't necessarily give you all the records :-)
In situations where a DNS client wants to do multiple queries at once, it
can either send a load of UDP queries then wait for the answers, or if it
has a TCP connection open, write all the queries in one go, then read the
answers. There's not really much need for fancy features to support
multiple questions when you can do hundreds of concurrent queries with one
or two sockets.
Happy Eyeballs version 2 requires concurrent DNS queries
I like to use `adns` for bulk concurrent queries
Much newer is getdns which has a more JSON-friendly design.
