If it's understood by the general public? No.
Programmers might understand it, but as far as I know, the asterisk is mostly used as a multiplication sign. Me personally, have only the asterisk in CSS and mySQL meaning 'everything'.
So even if your audience consist of programmers, it's possible it's not understood by everyone.
I can't really recommend a good substitute that's understandable for everybody, because I know too little of the context it will be used in.
If it's used in a search query you could remove the asterisk. The query '.com' will result in everything that ends with '.com'.
