- In rr sections it is now possible to specify a wildcard name, i.e. a name
  starting with the label *. The * in a wildcard can match one or more labels in
  a queried name, but only whole labels. For example, *.mydomain will match
  a.mydomain or www.a.mydomain, but not mydomain. Before you can specify an rr
  section with name=*.mydomain you must define some records for mydomain,
  typically NS and/or SOA records.
  Example:

    rr {
	name = mydomain;
	ns = localhost;
	soa = localhost, root.localhost, 42, 86400, 900, 86400, 86400;
    }
    rr {
	name = *.mydomain;
	a = 192.168.1.10;
    }
