Even people who wrote the page explaining the Raku \d can't actually follow how the broken \d works and assume it works on ASCII only in the rest of the document.
Can you find even a single actual Raku program out there, where \d is used, and it intentionally means <:Nd> and it would break the program if \d was changed to match <[0..9]>?
Just clicking randomly I see a lot of \d, and ALL of them assume that \d will be ASCII digits is everywhere. Explicit <[0..9]> are very rare. Anyone wanting <:Nd>? I haven't found a single case yet.
All I could say about pinging the IP is that your parser is just not able to convert the representation into an unsigned 32 bit integer. But it doesn't mean that no other parser is capable of this. Enough to say that dotted notation is a convention. Network addresses are just numbers in their nature.

docs.raku.org/language/regexes thinks "௩.௩.௩.௩" is a valid IP address, and good luck pinging that.

\ddirectly, and it confuses Raku with Perl 5 when filtering, but here's a start: https://github.com/search?q=filename%3A%22*.raku%22+language%3ARaku&type=CodeJust clicking randomly I see a lot of
