Why is it that there are no single letter TLDs or TLDs containing numbers? (excluding xn-- TLDs) As far as I know, there are no restrictions against TLDs that either have 1 letter or contain numbers. There are even TLDs such as .one and .seven that could be replaced with .1 or .7.

    Does this answer your question? [Number in the top-level domain?](https://stackoverflow.com/questions/9071279/number-in-the-top-level-domain) – Julia Mar 04 '21 at 15:36

    Besides your question being offtopic here as not related to programming, see question linked to by Julia (spoiler: I wrote one of the answer of that question). As for "that could be replaced with .1 or .7.", imagine you have IPv4 address `192.168.1.7` how do you know if it is an IP address or the imaginary `1` domain under the `7` TLD? – Patrick Mevzek Mar 04 '21 at 16:06
