Package Exports
- ip-regex
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ip-regex) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

options
Type: Object
exact
Type: boolean
Default: false (Matches any IP address in a string)
Only match an exact string. Useful with RegExp#test() to check if a string is an IP address.
includeBoundaries
Type: boolean
Default: false
Include boundaries in the regex. When true, 192.168.0.2000000000 will report as an invalid IPv4 address. If this option is not set, the mentioned IPv4 address would report as valid (ignoring the trailing zeros).
