How to allow subdomain in dnsmasq

Question

In my dnsmasq.conf file, I use the following rule o block all domains ending with .be:

address=/be/

But I would like to have an exception for youtu.be.

How can I do this?

This seems to work:

dnsmasq -C /dev/null -k \
  --server=/youtu.be/# \
  --address=/be/ \
  --log-facility=/dev/stdout \
  --log-queries

From the docs for the --server option:

The special server address # means, "use the standard servers", so --server=/google.com/1.2.3.4 --server=/www.google.com/# will send queries for google.com and its subdomains to 1.2.3.4, except www.google.com (and its subdomains) which will be forwarded as usual.

With this running on my local machine:

# dig +short foo.be @localhost
# dig +short youtu.be @localhost
