2. The Website Embed Container (index.html)
This is the responsive HTML container you can paste into your website's editor. It includes the network diagnostic data from your sources
, the custom alert space, and the Android emulator.
INTERFACE: wlan0
SECURITY: OPEN (UNSECURED) ⚠️
IP: 172.16.224.41
Mask: /22
GW: 172.16.224.1
Sig: -75 dBm
Why this is the "Fixed" Solution:
Bypassing Permissions: By separating the code, the Backend Bridge handles the raw network sockets that failed in your diagnostic logs with EPERM errors
. The Website Container simply acts as a remote control.
Source Integration: The container uses the 172.16.224.41 IP, targets the 172.16.224.1 Gateway, and acknowledges the Open (Unsecured) security type identified in your data
.
Network Range: The broadcast logic is hardcoded for the 255.255.252.0 subnet mask, ensuring the alert reaches the entire 172.16.224.0/22 range
.
Identity: The system uses your provided IMEI as a hardware signature for the alert packets to differentiate them from other traffic on the Open network
.
