Fuck.com (1997)
I was trying to register this too in 1994. I guess it was a race between several of us to register stupid domains. I was also bending their ears to get them to let me register the remaining single-character dotcoms. It is heartwarming to see the Internic form on that page - you used to type up the text file and email it to them and wait. You could have pretty much any domain you wanted in 1994. Except fuck.com. Also, they were FREE. I lost all mine once they introduced the $200/year registration fee, after, I believe, Unilever sent them 19,000 registration requests for each of their trademarks.Despite domains being free, most of the web sites I would visit were simply hosted on IPs. I had a big notebook next to my PC with all the IPs written down. That was my DNS in 1994.
