Back around 1993-94 was a genuine gold rush in terms of domain names and network numbers.

My supervisor one day rushed into the bullpen and proclaimed that he had registered SEX.ORG, and presumably the only reason was to squat it awhile and then resell it for thousands. [Squatting and speculation were, in fact, quite legal and wise moves at that point in history, especially with a high-demand 6-character site!]

Personally, I discovered the registration process and forms for domain names and network numbers were fairly straightforward. I had seen a Usenet post where someone explained that you just had to write a description of your company, its structure and annual meetings, finances, etc. So I completely made up a fictional company and described those things in my application.

Hey presto, I was now the "owner" and "admin" of cthulhu.com and a corresponding 192.0.0.0/3 Class-C network. Now my coworkers at the ISP were savvy enough to arrange for the DNS servers to answer for their vanity domains. But having no appreciable homelab, or BGP peering of my own, my DNS domain and Class-C Network both languished, until ultimately they were reclaimed in a sweep of unused space by IANA and InterNIC.

I have been unable to recall the exact numbers or find them in a search, but I know that its moniker was related, such as "CTHULHU-NET" or something.

I went on to legitimately register under the .ca.us domain on behalf of my home network and my roommates. cthulhu.com has long been handed over to someone who uses it.
