Python 3.12.1 : Check proxies on network.

Simple example about how to check proxies in network ...

import socket

# Get IP 
hostname = socket.gethostname()
workstation_ip = socket.gethostbyname(hostname)
#print("workstation_ip : ", workstation_ip )

# Put your IP's proxies from network
proxy_ips = ["192.168.1.1", "192.168.1.2", "192.168.1.3"]

# check IP proxy
if workstation_ip in proxy_ips:
    print("Is a proxy on network")
else:
    print("Not network proxy")

Example with sockschain python module:

import socket
import sockschain as socks

# Enable debugging
def DEBUG(msg):
  print (msg)

socks.DEBUG = DEBUG
# This would have set proxies using the standard environment variables:
socks.usesystemdefaults()

# Configure a default chain
chain = [
  'tor://localhost:9050/', # First hop is Tor,
  'tor://localhost:8080/', # 8080 port,
  'ssl://proxy.example.com:8443/', # SSL to proxy.example.com
  'http://user:pass@proxy.example.com/' # ... try auth to an HTTP proxy
]
socks.setdefaultproxy() # Clear the default chain
for hop in chain:
   socks.adddefaultproxy(*socks.parseproxy(hop))

# Configure alternate routes (no proxy for localhost)
socks.setproxy('localhost', socks.PROXY_TYPE_NONE)
socks.setproxy('127.0.0.1', socks.PROXY_TYPE_NONE)

... the result is:
