README

Generate a random private IPv4 subnet of specific size (bitmask), or pick a random address from a defined private IPv4 network.

Usage

Require the class in your own project using composer:

composer require gregorj/randomip

The static functions can be called easily in your code:

//echos a random class B (172.[16-31].0.0/12) network for 6 hosts.
echo \GregorJ\RandomIP\RandomPrivateIPv4::randomNetwork('B', 29);

//echos a random IP address inside the network 192.168.21.0/24
echo \GregorJ\RandomIP\RandomPrivateIPv4::randomIP("192.168.21.0", 24);

Restriction

This code is only suitable for private IPv4 networks. Therefore the bitmask cannot be lower than the following:
