Part of bzrlib.tests.test_smart_transport View In Hierarchy
RFC 2606 states that .invalid is reserved for invalid domain names, and also underscores are not a valid character in domain names. Despite this, it's possible a badly misconfigured name server might decide to always return an address for any name, so this feature allows us to distinguish a broken system from a broken test.
