It exists in whois and in DNS, with valid SOA and NS records and even an
A record, which points to valid routable IP space. Oops.
It's a "reserved" domain, per RFC 2606 / BCP 32. But it's reserved for
use as an example, not for testing purposes.
When you special-case domains, you create new code-paths which need
their own debugging, adding their own complexity and causing more
problems if it's a domain which anyone else might legitimately (or not)
be trying to use.
Theres nothing keeping a software author from using a sub-domain of one
of their own domains as a realm for testing purposes. DUMMY.PDC.KTH.SE
or somesuch. Include a note in a file stating that it's reserved for
use by software X for tests Y and should not be used for any other
purpose and possibly even create a TXT record for it, saying the same.
