Source code: https://github.com/SkyLined/LocalNetworkScanner/ … This is a work in progress. It was put together from scratch in an hour or so.

scanning uses a side-channel attack (timing) on requests - that idea is from early 2000s. Adding local IP discovery is new.

Version 2 is out, with slicker UI and port enumeration. Live: http://blog.skylined.nl/LocalNetworkScanner/ … Source:https://github.com/SkyLined/LocalNetworkScanner/ …
Thanks. Twitter will use this to make your timeline better. UndoUndo

Now with local subnet detection. Tested on Windows in Chrome. YMMV
-
successfully detects my /16 subnet. would take over an hour to scan it completely. However, it breaks Chrome after ~1/2hr.

it thinks half my home network (even a bunch of IPs that don't exist) have 80/443/445 but it does identify 'you' correctly
-
@pathetiq@_jsoo_@guiguiabloc@jupenur I've made some improvements, please try again. Let me know your browser/OS if it still fails -

-
what browser on what OS is this? Do any of the ips with a tux icon or "?" actually exist? I do not know your network...
-
chrome on mac; the nmap shows you what IPs exist; can answer more later
-
Sorry, I had overlooked the nmap. So it detects hosts that are up as *nix, and unused ips as unknown... I should add a debug log.
-
yes. Most of the hosts that are up are in fact Linux, secretly or openly, but not all :)

Possible bug: first IPs *.*.*.1-10 all get Windows when there is nothing there.
-
Thanks, but there's not much I can do without knowing why... Maybe you can play with the source to find out yourself? Thanks!
-
Np, will check that up.
-
My software being infallible and all that, I'm sure it's just some blackhat installing secret devices on your network... :)
-
I got afraid at first too! :\ I did verified ! haha

Any idea on why it does not work when hosted in https site?
-
That should now be fixed - XHR was always using http://, content mixing may not allow that.

running it on 'WiFi in de trein' now :) looks like I'm getting a /24 (10.87.1.42) of unknown except again a correct 'you'
-
oh, tuxes at .196 and .197 which I cannot even reach. This is mostly confusion I think :)
-
Note that it does not attempt to determine your sub-net but always assumes /24 (i.e. it scans xx.xx.xx.*).
-
I was already impressed it found out -which- /24 :)
