Re: [Dnsmasq-discuss] DNSMASQ on Ubuntu VirtualBox.
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.

That's your first problem, unmaintained obsolete OS and likewise dnsmasq. 18.04 which is also dying shipped dnsmasq 2.79. That's long gone. Likely that also affects your web server. Ubuntu maintain a very very small fraction of available packages for five years -- only the "main" series. But dnsmasq is in Ubuntu's "universe" series, where "supported" is promising too much. With some luck, you may receive updates for a few months. I've left Ubuntu behind because usually bug reports against packages would expire for my reports. Upgrade.

In short: Check if the ip addresses still work, and if the MAC addresses in your router changed in the VBox re-setup. Other than that, nobody will be able to help you on your software museum.
