Having had devices with txl (Airport Berlin Tegel, now closed, new
Airport BER) in their DNS Name and devices in a CoLO in Weismüller
Strasse Frankfurt which got first renamed and then sold and again
renamed (afaikr) (now fra28)... I think that a convention like
<street>.<un-loc>.<tld> is worth to keep in mind.
