Supercontest Proxy

Connect your computer to a functioning router, then open any browser, go to the settings and enable manual configuration. Specify the IP, gateway with DNSI and subnet mask in the appropriate fields. In the "Home network" tab, under "Computers", go to "IPMP Proxy" and turn off this function. Under "System", click on the gear symbol, and under "Components", specify the Proxy UDP HTTP utility and click "Refresh".

The term "public" should be understood to mean open proxy servers. That is, they can be used by all users without exception. They can be insecure and are often quite overloaded, so the connection speed or response time when using public proxies can be very slow.

It depends on the purpose for which you plan to work with proxies at all. Personally, one is enough for myself. But if you plan to do massive parsing, it may not be enough to have 100 pieces.

To make a selection in a drop-down menu using Selenium, you can follow these steps:

1. Import the necessary libraries:

from selenium import webdriver
from selenium.webdriver.support.ui import Select

2. Create a WebDriver instance and navigate to the webpage containing the drop-down menu:

driver = webdriver.Chrome(executable_path='path/to/chromedriver')
driver.get('http://example.com')

3. Locate the drop-down menu element using its id, name, xpath, or css_selector:

drop_down = Select(driver.find_element_by_id('dropdown-menu-id'))

4. Select an option from the drop-down menu:

# To select an option by visible text
drop_down.select_by_visible_text('Option Text')

# To select an option by its value attribute
drop_down.select_by_value('option-value')

# To select an option by its index (0-based)
drop_down.select_by_index(2)

5. Close the WebDriver instance:

driver.quit()

Here's a complete example:

from selenium import webdriver
from selenium.webdriver.support.ui import Select

driver = webdriver.Chrome(executable_path='path/to/chromedriver')
driver.get('http://example.com')

drop_down = Select(driver.find_element_by_id('dropdown-menu-id'))
drop_down.select_by_visible_text('Option Text')

driver.quit()

Remember to replace 'path/to/chromedriver' with the actual path to your ChromeDriver executable and 'dropdown-menu-id' with the actual ID of the drop-down menu element.

The easiest option is to use ready-made online proxy checkers. For example, Hidemy.name, which shows the type of protocol used. Or you can simply run Speedtest - this will show you the bandwidth and response speed (ping).
