//=> true

console.log(validate4('127.0.0.1'))
//=> true

console.log(validate6('127.0.0.1'))
//=> false

console.log(validate('2001:0db8:85a3:0000:0000:8a2e:0370:7334'))
//=> true

console.log(validate4('2001:0db8:85a3:0000:0000:8a2e:0370:7334'))

Acknowledgements

The code is mostly based on this wonderful library: beaugunderson/ip-address

All regexes used are audited for catastrophic backtracking by this module: substack/safe-regex
