This may not be the best way to go about this (and suggestions would be appreciated), but if I choose this route, I would want to know the IP address of each of the interfaces together with its subnet mask.

if you really need this, you might look at the implementation for %get-ip-interfaces in clozure. it uses getifaddrs in a fairly transparent manner, so, if you're unix-based, you should be ok with it.
I need this to work on Windows and *nix, which is why I can't use IOlib or other Unix-based solutions. That said, Clozure does run on Windows, so hopefully the code you mentioned has already been ported.
There's an internal function ccl::%get-ip-interfaces that's conditionalized for a bunch of platforms. I can't really recommend that you use it, of course, but it might be something to look at.
I glanced over the source briefly, and might give porting it to CFFI a shot when I can find some free time.
I've ported the code to CFFI, and tested on SBCL, CCL, ECL, and Allegro on Mac OS X, SBCL on Linux, and SBCL on Windows. The source code is available as a darcs repository at: http://common-lisp.net/~eslaughter/darcs/ip-interfaces/ The code is licensed under the LLGPL to maximize license compatibility with Clozure CL. -- Elliott Slaughter "Don't worry about what anybody else is going to do.

A project page for ip-interfaces has been put up on common-lisp.net: http://common-lisp.net/project/ip-interfaces/ <http://common-lisp.net/project/ip-interfaces/>Enjoy. On Sun, Mar 21, 2010 at 10:27 AM, Elliott Slaughter < elliottslaughter@gmail.com> wrote:
