When introducing IPv6 support, we map the third digit of the IPv4
address (X) to the 6th byte of an IPv6 prefix "fd02:db8:X::/64"
However, the docker daemon seems to use "fd02:db8:1::/64" internally
for its default network, so creating a docker network with the same
IP address is failing.
Let's move the MSC test suite to another sub-net (1->20) to avoid
related problems.

Ideally we would want to launch a group of containers with their own
private network segment and use the same static IP addresses in those
isolated networks.
The stupidity of docker is requiring unique IPv4 addresses even on
isolated (!) networks. This means we have to manually give each of our
test setups a different subnet, and then we can at least run one
instance that test in parallel to at most one instance of each other
test.
If this weird reestriction about unique IPv4 addresses didn't exist,
we could start any number of test runs in parallel.
