Nice one ! Need this too

Would this be a duplicate of #1568? Yours looks like it's a more complete solution though.
Maybe a discussion should be setup and close one of the PRs in favor of the other.

Sorry for the late review. Thank you @neilime for your contribution! I really like your approach and the fact that you used the same logic behind isIP.
Can you please remove validator.js and validator.min.js (We stopped tracking those files in the library) and discard the unrelated changes in src/lib/isMobilePhone ?
Thank you 🎉

@tux-tn I have rebased with master, let me know if everything looks good to you
