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.
