I guess like any other second-level domainname: Fetch your piggy bank, and then go out to look for it. Peculiar things that pop in my mind right now: - given their length, know that they are scarce; you can expect that scarcity to drive the price - some TLDs might have a minimum length for subdomains that are available to the public - expect a lot of them already registered since longtime, or reserved by various individuals or organizations [0]; intuitively, the chance of those getting released soon feels slim You can use DNS (check the dig [1] utility), in combination with WHOIS if you want to gather information. Or a website of a domain registrar like [2]. Keep in mind that you might be watched doing that, information that could be used to drive up the price again. Or, if you really have good ideas, you convince one of the current registrants to use his domain (guessing here that a lot of those domains are not really in use).
