Have you checked the contents of /etc/hosts file? Sometimes the local
hostname is added there to save resolution of local hostname again and
again. Could its record override address= you wanted to assign? I doubt
there is defined and documented order if they conflict.
Does you /etc/hosts contain:
127.0.0.1 localhost xxx ?
it might help if you remove expand-hosts from dnsmasq configuration and
use aliases in the file itself. But avoid conflicting definition with
dnsmasq. Consider also using host-record, which will match only
xxx.mydomain.com, not example.xxx.mydomain.com.

So here is my DNSMASQ problem.
I'm running to VirtualBox Ubuntu 16.04 servers on two seperate 2011
mac mini servers (macos High Sierra).
Each of the two VirtualBox Ubuntu servers runs a LAMP website (Drupal
based) and a DNSMASQ dns server.
The network is controlled by a Fritz!Box 7590. In the configuration
the two different DNSMASQ servers are listed instead of the standard
provider DNS.
VirtualBox One:
static IP 192.168.2.50
website IP 192.168.2.50 xxx.mydomain.com
DNSMASQ IP 192.168.2.50
VirtualBox Two:
static IP 192.168.2.55
website IP 192.168.2.55 yyy.mydomain.com
DNSMASQ IP 192.168.2.55
Fritz!Box (router)
Gateway 192.168.2.1
DHCP 192.168.2.100-200
So far so good. This setup seemed to have worked for hals a year. Then
recently I had to restore one of the VirtualBox servers. And now it
only works somewhat. In short:
Each of the two DNSMASQ servers will only resolve the website on the
other VirtualBox, the website on the same VirtualBox will resolve to
localhost.
So if I want to be able to reach the domain in VirtualBox One I have
to use the DNSMASQ server in VirtualBox Two and the other way around.
Here is the dnsmasq.conf file from VirtalBox Two (for Box One just
substitute the 192.168.2.50 for 192.168.2.55).
cat /etc/dnsmasq.conf
# DNS configuration
port=53
#/etc/dnsmasq.conf
domain-needed
bogus-priv
expand-hosts
# The address 192.168.2.55 is the static IP of this server
# You can find this ip by running ifconfig and look for the
# IP of the interface which is connected to the router.
listen-address=127.0.0.1
listen-address=192.168.2.55
bind-interfaces
# Use open source DNS servers
server=8.8.8.8
server=8.8.4.4
# Create custom 'domains'.
# Custom 'domains' can also be added in /etc/hosts
address=/xxx.mydomain.com/192.168.2.50
address=/yyy.mydomain.com/192.168.2.55
# address=/www.anotherdomain.com/192.168.2.50
# address=/anotherdomain.com/192.168.2.50
# address=/www.stillanotherdomain.ch/192.168.2.50
# address=/stillanotherdomain.ch/192.168.2.50
I am not very experienced with DNS servers, so can you possible point
me in the right direction if you see an error.
Thanks
Paul
