Private IPs on local networks (192.168.0.0/16, etc), or globally routed IPs assigned from your ISPs netblock?

- svnpenn 6y agoIP assigned from ISP
- exikyut 6y agoI'm mildly curious how your ISP works then. Like the other commenter said, this tool will change your Windows device's MAC, not the modem's. To be clear, there's your device's MAC, the Wi-Fi AP's MAC and the modem's WAN-facing MAC. (Integrated Wi-Fi router/modem combos obviously have both.) If this tool is successfully getting you new public IP addresses, something VERY weird is going on with your (probably integrated) modem.
- svnpenn 6y agoI did this many times back when I just had a plain cable modem, not router or anything. I havent tested since I switched to a Modem Router combo, I would suspect it wont work under that setup. But yes, my original point stands. I can run the tool, change my network cards MAC, restart the Modem, and I get a new public IP address. Ive been doing this for years to bypass IP blocks.
- exikyut 6y agoAhh, that explains a bit: let me guess, your modem had a single Ethernet port on it, which you were running directly to your computer? That means the modem was cloning your device's MAC address onto its own WAN interface. Which is... weird, but would have had some kind of logical motivation. Maybe it meant the modem vendor didn't have to maintain their own MAC registration ("just copy the device's!"), or maybe it was an ISP "what kinds of devices are our customers using?" kind of thing (the majority of results would have been routers, not single devices). Or maybe this is normal for cable modems (never used cable myself, just ADSL2+).
