Crowd Proxy

Before you change your proxy server, you should decide what kind of proxy you would like to install. There are a lot of choices, depending on your needs. Every buyer, when buying a proxy server, is given all the necessary information with the data for access - username and password, port, IP address. Without these data, you can't install and configure the proxy.

All you need to know when using a web proxy is the address of the web site of the proxy server. A web proxy is like a browser built into a web page. Usually, it always has a bar for entering the URL of the web site you want to open. After entering the URL of the web proxy server address into the address bar of the browser, enter the address of the desired web site into the proxy URL and press "Enter".

Technically, a proxy is an ordinary computer or server connected to a network (local or Internet). It accepts traffic from the user, redirects it to the address that was specified in the request. And then receives the response from the server and transmits it to the user's equipment. That is, it is actually an intermediary.

The easiest way to do this is to use online proxy checking services. For example, Hidemy Name. It is free, displays technical data about the connection, and at the same time it also checks the ping.

In Python, when using socket module, both TCP and UDP sockets have different local addresses (laddr) because they serve different purposes and have different characteristics.

TCP (Transmission Control Protocol) is a connection-oriented protocol that ensures reliable, in-order, and error-checked delivery of data between the sender and receiver. It uses a connection establishment phase to establish a session between the sender and receiver, and it maintains a connection state throughout the data exchange.

UDP (User Datagram Protocol) is a connectionless protocol that provides a simple and fast way to send and receive data without the overhead of establishing and maintaining a connection. It does not guarantee the delivery, order, or error-checking of data packets.

Here are the main differences between TCP and UDP sockets in Python:

1. Local Address (laddr):

2. Connection:

3. Reliability:

In summary, the different laddr values in TCP and UDP sockets are due to their different purposes and characteristics. TCP sockets use laddr to represent the listening endpoint, while UDP sockets use laddr to represent the sending or receiving endpoint.
