See > [RFC2606] (Eastlake, D. and A. Panitz, "Reserved Top Level DNS > Names," June 1999.) for example domain names that can be used. Why the SHOULD? Presumably, because you don't want naive folk to take the examples in the RFC and use them in local config files and such, causing problems or other undesirable effects when they (unexpectedly) get used in the real world.. But in cases where this really is not a concern, there is also presumably not a need to _require_ use of the example names.
