splitNetworkInHalf()

splitNetworkInHalf(network)

Description

Method that allows you divide ip network into two equal networks.
Ip network must be correct. (see validation)
And prefix of network must be smaller than 32.

Contract

Parameters:

• network: string — ip network.

Return:

• [string, string] — array with two resulting networks.

Exceptions

Invalide ip network!:

• entered argument is not a correct ip network.

Can not split network with /32 subnet mask!:

• entered network has prefix: 32.

Usage

ipv4.splitNetworkInHalf('222.245.160.0/22');       // ['222.245.160.0/23', '222.245.162.0/23']
ipv4.splitNetworkInHalf('222.245.162.0/23');       // ['222.245.162.0/24', '222.245.163.0/24']
ipv4.splitNetworkInHalf('222.245.163.0/24');       // ['222.245.163.0/25', '222.245.163.128/25']
ipv4.splitNetworkInHalf('222.245.163.128/25');     // ['222.245.163.128/26', '222.245.163.192/26']
ipv4.splitNetworkInHalf('222.245.163.192/26');     // ['222.245.163.192/27', '222.245.163.224/27']
ipv4.splitNetworkInHalf('222.245.163.224/27');     // ['222.245.163.224/28', '222.245.163.240/28']
