[Bug 1228955] [NEW] dnsmasq changeds virtualbox guests PTR queries into A queries

[Bar Ziony]

Public bug reported:

Hello,

For some reason, when trying to resolve a PTR query (host -t PTR 8.8.8.8 for example) from a VirtualBox guest (Doesn't matter which OS), the resulting query on the host (Ubuntu 12.10) eth0 on wireshark is an A query for 8.8.8.8.in-addr.arpa, which of course fails.
This happens for all PTR queries, public and private.
When I stop using dnsmasq in my host (by commenting it out on /etc/NetworkManager/NetworkManager.conf), everything works as expected.

I know this is not a VirtualBox issue.

Resolving the same PTR queries exactly (with the same 'host' utility) on
the host works great.
