The test is

     $node->connect_fails(
         "$common_connstr host=192.0.2.1/32",
         "IPv4 host with CIDR mask does not match",
         expected_stderr =>
           qr/\Qserver certificate for "192.0.2.1" (and 1 other name) 
does not match host name "192.0.2.1\/32"\E/
     );

which is not using a valid host name to begin with.  What is the purpose 
of this test?
