DNS - multiple question with a single query

[Julio Olivares]

I'm currently developing a DNS utility which is working greatly with a
single qname in a query. However, if I try to perform a query for
multiple qnames I got a format error.
I've checked the datagram with Wireshark and the packet is well
formed, and by reading the RFCs I can't find anything relevant about
multiple qnames.

I'm testing it on a a Bind 9.4.2 server.

This is not an issue, I can perform multiple queries, but I woould
like to understand where is the problem since RFC1035 defines multiple
qnames in a sngle query.

Any help would be appreciated.

Regards,
