The company in which I work will implement a corporate network in which there are several locks of IPs and Ports.
I need to get all the IPs and ports I need to use to request their release.
I work with PHP, Git, and Composer and I have no idea what IPs I need to request for release (especially in the case of Composer, where there are several dependencies and some, it has other dependencies).
Can anyone help me identify this?
NOTE: Using Ubuntu 18.04
