Welcome this REST API has an will help person who can not calculate network addresses such as broadcast address, network address, how to divide the network into a subnet and perform determine if the addresses belong to the same network.

The type of address ( addressType, maskType) is a "DECIMAL", "BINARY", "NUMBER_OF_ONES" (only for mask)

This api can solve four types of tasks:

Divide network to subnet:

Request: .../divideNetwork?divideNetworkWithSubnet=2

Request param divideNetworkWithSubnet is between 1 and 131072 ( the limit is set by response size from 65537 to 131072 number of subnet a response has round 50MB)

    "addressType": "DECIMAL",
    "mask": "255.0.0.0",
    "maskType": "DECIMAL"
  }

Response 200 Status OK
