You're right, I meant gTLD. Unfortunately I can't edit my comment anymore.
I think ccTLDs are restricted to two letter codes even if the country of Internia were to be be founded. The only exceptions I can think of are the localized names (.台湾 and 中国 for countries like Taiwan and China) which are technically encoded as .xn--kprw13d and .xn--fiqs8s. Pakistan's پاکستان. is the first ccTLD I've seen that's more than two visual characters when rendered (with the added bonus of being right-to-left to make URL rendering a tad more complex) so for Internia to claim .intern as a ccTLD, they'd probably need a special script.
