Netcut DOES NOT WORK if the router has Mask IP enabled.

[hellupinharlemParticipant]

Just incase admin you don’t see my responses in other threads.

If the network administrator chooses to “Do something” about users using netcut, they can opt to mask the real IP address as a mechanism to break netcut.

Before netcut showed the true IP address and name of clients. Lets say this is 192.168.2.1-255 for all users on the internet. However, it no longer shows it but shows a fake IP, which is 190.134.2.1-255 for all users, and with further research it looks as if in Winbox (Mikrotik’s OS) the DHCP settings were set to 1. change gateways in the DHCP window, and 2. Setting random IPs in the IP windows which has all user connected gateways not match with real ip.

Netcut now cannot know the real gateways IP as netcut only sees the 190.134.x.x and not the 192.168.x.x so it doesn’t work. And such preferences on the router side allow users to still connect while shielding them from being cut off, essentially MASKING THE IP, in the same manner you would mac clone. AS such netcut options do NOT affect the internet connection in any way and cease to function as intended.

If the end user is out and about and has no access to teh router setting to disable it, netcut is essentially broken.

While my example specifically indicates Mikrotik router (as I’ve ran into this now with more and more routers of this brand), this problem can exist because the option to mask the IP is available on all commercial routers now.

interesting.

Can you run following command in your PC (that use the Router) command line and give me output?

ipconfig
arp -a
route print

thank you

Arp -a config Note the physical address at the 70.10.0.1 was changed for privacy concerns (can give you the real one privately) but the rest are untouched.

Let me also add that if I go to whatismyip.com and look up my address, a different one is shown than the 172 one listed, proving my point its masked. The original IP that netcut used to show is visible.

Side point: my real IP and the IP of the router can also be seen by routerscan’s software, so whatever mask protocol is being used does not block that.

it looks normal.

have you tried Netcut for Android phone?

[hellupinharlemParticipant]

Of course it looks normal Admin, the MaskIP is enabled on the router broadcasting a different IP than the real one.

Like I said, if I go to what is my IP, I get a completely DIFFERENT ONE, the real one, for my IP address than what now shows on Netcut. I know what my real IP is, and I’ve seen it on netcut, up until this mask router thing is enabled. Even brute forcing the router does nothing but reveal the original IP on the main connection, and once the router recycles, even that does not show up.

This is a serious problem, PC or Android and if it isn’t resolved, I’m sorry, netcut is BROKEN.
