Set windows bat scripts for IP addresses and Proxies

I can't remember where I copied it. To prevent loss, make a backup.

The first part of this Code sets the IP address to be automatically obtained, and then sets the proxy server to "porxy: 80 ";

This Code sets a fixed IP address, DNS, and other configuration information, and deletes the proxy settings (the IP addresses in this article are fabricated by me and need to be filled in according to the actual situation ).
