CIDR

Public API

CIDR.fromString(cidr)

  • cidr: String String representation of a CIDR, ex: 10.0.0.0/16
  • Return: CIDR CIDR created from the string.

Parses cidr string and creates a CIDR object.

If possible, splits the cidr into two CIDRs that are half the size.

Releases

We follow semantic versioning policy (see: semver.org):

Given a version number MAJOR.MINOR.PATCH, increment the:

MAJOR version when you make incompatible API changes,
MINOR version when you add functionality in a backwards-compatible manner, and
PATCH version when you make backwards-compatible bug fixes.

caveat: Major version zero is a special case indicating development version that may make incompatible API changes without incrementing MAJOR version.
