I see a lot of friends in the forum looking for this thing. I couldn't find it when I needed it some time ago. So I wrote this. There are still many bugs to fix and improve, but basically it works. Now I'm sending it out to those who need it.

The code is not encrypted. Friends who need it can modify it themselves. I wrote this just for my own convenience.
I didn't consider the convenience for the public..
I'll improve it if I have the opportunity in the future..

I don't know what the use of such a long piece of code is... I tried it, and I only know that it switches gateways like 192.168. But if it's another gateway, it simply doesn't switch. This is called automatic? It's not as convenient as changing it manually.

I have already said. Writing this is just for my own convenience. I didn't consider the needs of the public. Those who need it can take it and modify it.

As for why it can only modify the 192.168 segment, I think anyone with a little common sense should understand. Some things are completely impossible to achieve automatically. Even if it can recognize your IP, the program may not know which segment you want to modify, and it can't know how many segments you have. So I used the ::::::: symbol above this thing to declare it as a variable, and users need to modify it themselves. If you want to enjoy the fruits without effort, you won't learn anything..

This can first obtain the current network segment... save it...

Then change the network segment...

Finally, when it needs to be restored, just take out the previously saved network segment and restore it. Isn't that okay...
