Hi Hemanth,
Apologies for the delay, April has been ... interesting? ... for me.

You're right that IronPython does not support pywin32, because
IronPython doesn't support C extensions in general. In this specific
case it's probably because scapy checks for Windows using sys.platform
== 'win32' instead of os.name == 'nt' and it's trying to run a Unix
codepath (uname is the giveaway, it's part of os on Unix but not
Windows).

It might be possible to replace the calls into pywin32 with ctypes
calls but it would require changing scapy.
