Why the same public IP does not mean the same network environment

A public IP check is useful, but it is not a complete network test. Two workstations can show the same IPv4 exit in a browser and still behave differently in DNS resolution, IPv6, WebRTC, or applications that ignore the configured proxy.

Start with the question you actually need to answer

For a team deployment, the useful question is not simply “Do these machines show the same IP?” It is “Does the application I care about follow the intended network path?”

That distinction matters because different applications use different networking stacks. A browser can honor an HTTP proxy while a desktop program opens a direct socket. A SOCKS5-capable tool may proxy TCP correctly while another component resolves DNS locally. IPv6 may remain available even when an IPv4 proxy is working.

What NetConfiger can control in the current proxy-distribution mode

NetConfiger can expose an HTTP and/or SOCKS5 proxy on a Windows host that already has a usable network connection. Compatible downstream applications point to the host IP and proxy port. Their supported traffic can then reuse the selected Windows-side exit.

This is explicit proxy distribution. It is not the same as making NetConfiger the default gateway for every packet on a downstream device.

A practical consistency check

Use the real application and check the path in this order:

1. Confirm the Windows host itself reaches the required destination through the intended exit.
2. Configure the downstream application to use the NetConfiger HTTP or SOCKS5 endpoint.
3. Check the application's observed public IP.
4. Check how that application resolves DNS. Do not assume browser DNS behavior represents every program.
5. If IPv6 is enabled, test IPv6 separately instead of automatically disabling it.
6. For browser workflows, inspect WebRTC behavior if it matters to the application.
7. Temporarily remove the proxy setting and confirm that the result changes as expected. This is a simple way to prove that the application is actually using the proxy.

What a mismatch means

A mismatch does not automatically mean the Windows host or NetConfiger is broken. It may mean the application is bypassing system proxy settings, using UDP, resolving DNS locally, or opening a direct IPv6 connection.

The fix therefore depends on the application. If it supports an explicit proxy, configure that path correctly. If it does not support HTTP or SOCKS5, a proxy-distribution product cannot transparently take over all of its traffic; that requires a different system or gateway-level design.

The useful deployment record

For each workstation, record the host address, proxy protocol, port, application name, expected exit, and the result of the verification test. That record is more useful than a screenshot of a single IP-check page because it tells the next person exactly what was tested.
