How to get a list of networks from the IP range in php?

Question

PHP

Please tell me a php solution to translate a range of addresses into a network with a mask.

For example:

80.75.133.0-80.75.135.127

Translate to:

80.75.133.0/24
80.75.134.0/24
80.75.135.0/25

As an example, I can show the following site:
ip-calculator.ru

The second option is "Get a list of networks"

I can make requests to it through the same curl and translate the ranges I need in the networks with a mask, then parse them, but this is a terrible crutch :) I would like to find a solution to do this in my script.

Thank you.

Answer 1

Consider an example of writing a range of IP addresses in the form 10.96.0.0/11. In this case, the subnet mask will have the binary form 11111111 11100000 00000000 00000000, or the same in decimal: 255.224.0.0. 11 bits of the IP address are assigned to the network number, and the remaining 32 - 11 = 21 bits of the full address - to the local address in this network. In total, 10.96.0.0/11 means the address range from 10.96.0.1 to 10.127.255.255.
