Well, well, well.

If we go outside of dottted decimal notation of IPv4, we can have addresses starting with 624. They can also be in decimal, octal, and hexadecimal.
Oh, and IPv4 also supports shortening from middle right in dotted decimal. For example, 127.0.0.1 is too long, often you may be able to use 127.1.
Or you can go to Cloudflare's https://1.1/

    While you can convert (or rather represent) an ipv4 as decimal, op indirectly stated that they were in dotted decimal notation and as such the leading 624 doesn't work in that context.

    Also shortening ipv4 is cursed, why must you share this knowledge?

    Also also, curious to note that glibc parses 1 as ipv4 0.0.0.1 and not ipv6 ::1, probably because they predate ipv6.
