Another wide-spread non-standarized TLD is .box. It is used by Fritz!Box home routers (https://en.wikipedia.org/wiki/Fritz!Box https://en.wikipedia.org/wiki/Fritz!Box). They are shipped with a really good operating system and handle the resolution of .box very seamless, integrating all the names of registering DHCP devices (i.e. you can resolve your-iphone.box in your LAN). The TLD stems from the "pun" http://fritz.box http://fritz.box.
