I’m pretty sure every possible two letter combination was taken before that policy came out. There used to be an old site that visualized the two- and three-letter domain name space as two- and three-dimensional grids. It was neat seeing the pixels fill in over time.

Looks like you're right - from Wikipedia: Two-letter .com domain names were never reserved. It was possible for anyone to register them in the very early years of the Internet (from 1985 to 1998). The first company to own an active Two Letter Domain is Hewlett-Packard. Since 1998 all permutations of the 26 × 26 = 676 .com domains have been registered and (barring the very unlikely event of a lapse in registration) they can only be obtained by buying them from the previous owner. https://en.wikipedia.org/wiki/Single-letter_second-level_domain https://en.wikipedia.org/wiki/Single-letter_second-level_dom...

  Since you can also use numbers, shouldn't that read "all permutations (...) 36x36 = 1296 .com domains" ?

    > Two-letter Numbers are not letters, but you're right, that's the correct number of possible two-character .com domains.

  Yeah, your "early 2000s comment" really stuck out to me. I'm surprised they lasted through 98. I remember thinking domain names were for people who "really knew what they were doing" and then was pissed I didn't register one before NetSol started charging (IIRC there was a big outcry because Kraft foods registered like 137 domains right before they started charging).
