This makes me think of the historical hxxp://simtel.net/ domain (now web spam, whence the hxxp), see e.g. https://web.archive.org/web/20010602231157/http://www.simtel.... The first time seeing it I was always thinking to something like "simulated telnet"...

If you want a rabbit hole, this is the likely owner of both tel.net and sms.net = https://www.gbnet.net/

Also teln.et (Ethiopia)
