No, it's defined in Emacs' process.c:

,----[ C-h f network-interface-list RET ]
| network-interface-list is a built-in function in `C source code'.
| 
| (network-interface-list)
| 
| Return an alist of all network interfaces and their network address.
| Each element is a cons, the car of which is a string containing the
| interface name, and the cdr is the network address in internal
| format; see the description of ADDRESS in `make-network-process'.
`----

But it's compiled only conditionally, depending on having the net/if.h
header file and maybe some configure switches.  I don't know if that's
available on windows, as I can see from your mail header.
