>This is because under the Verisign GRS, name servers for second level domains also get entries created. So, you can create a Whois entry for an arbitrarily named server, like ycombinator.com.paulgraham.have.mychildren.com, and it will show up. I haven't been involved in Whois and tld stuff in a while, but back in the day, these host Whois records were allowed because the gtld servers needed glue for domain names - after all, if your domain name is ycombinator.com and your name server is ns1.ycombinator.com, how can a resolver recurse to find that, unless te gtld servers also have an A record for that label/object? So, you could just go create arbitrary A records at the gtld level, which would cause a corresponding Whois entry to be created. Hilarity for all involved.
