Proxy IP Range

There are lots of ways to use them. For example, you can swap your real IP address location for an American one, thus getting the opportunity to watch Netflix at a bargain price. Or you can set up parsing traffic through a proxy to test the security of your web applications. Or you can create a proxy server on your local network that allows traffic through and blocks requests to certain sites.

When scraping data from a website, it's common to encounter empty strings or strings that consist only of whitespace. To get rid of these empty or whitespace-only strings, you can use various approaches depending on the programming language you're using. Below are examples in Python and JavaScript.

Python:

# Example list containing strings with some empty or whitespace-only strings
data = ["apple", "", "  ", "banana", "  ", "cherry", ""]

# Remove empty and whitespace-only strings using list comprehension
filtered_data = [s.strip() for s in data if s.strip()]

# Print the filtered data
print(filtered_data)

In this example, s.strip() is used to remove leading and trailing whitespace from each string, and if s.strip() is used to filter out empty and whitespace-only strings.

JavaScript:

// Example array containing strings with some empty or whitespace-only strings
const data = ["apple", "", "  ", "banana", "  ", "cherry", ""];

// Remove empty and whitespace-only strings using filter and trim
const filteredData = data.filter(s => s.trim() !== "");

// Log the filtered data
console.log(filteredData);

In JavaScript, s.trim() is used to remove leading and trailing whitespace, and s.trim() !== "" is used as a condition in the filter function to exclude empty and whitespace-only strings.

Most often it is used to substitute your real IP address. An example of when this is needed: watching shows on Netflix that are only available to US users. A proxy can be used to make a user logging in from anywhere in the world will be identified by the IP address as a US user. Another option is to test your site through a local web server. A proxy in this case is used to intercept all the traffic in order to analyze it further for errors and failures.

A proxy server acts as an intermediary between the client and the requested Internet resource. It is assigned the role of a kind of gateway or filter, which is responsible for submitting a request, receiving the required information and providing it to the user. The proxy server, if necessary, can make changes in incoming and outgoing data, the nature of which will depend on the type of proxy and its settings.

Every proxy server is of the type 168.1.1.1:8080, where the first part before the colon is the IP address of the remote computer through which the connection is made. The second part (after the colon, in this case 8080) is the port number through which your equipment will connect to that very remote server.
