    Hi
    If you get a shell on the remote machine then you can probably use
    Psexec to do a ipconfig and find out the internal network
    range/subnet.
    There are many scenarios and methods in variance, It all depends on
    what sort of access method is being employed and which stage of the
    penetration you are in currently

    Subject: Find out the subnetting of a company

    During an internal black-box penetration test, from a subnet of a
    company (with or without DHCP), how do you find out the structure of
    the other subnets of network? In particular, how do you
    determine/discover the subnetting of the IP space of a company?

    An example:

    - - IP network of the company XYZ: 10.0.0.0/8 (I use a private class to
    avoid the use of a real address space)
    - - I?m in the subnet 10.0.0.0/24

    How do you find out the structure of other subnets that are part of
    the network 10.0.0.0/8?

    Il Prof.
