In e-mail, proxy servers are used for secure data exchange as well as for collecting e-mails from several e-mail addresses at once. For example, this is how Gmail works, which also allows you to receive e-mails from mail.ru and other e-mail services.
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):
TCP Socket: The laddr for a TCP socket contains the IP address and port number of the local endpoint that is listening for incoming connections. This is the address and port that the server binds to and listens on for incoming connections.
UDP Socket: The laddr for a UDP socket contains the IP address and port number of the local endpoint that is sending or receiving data. This is the address and port that the client uses to send data or the server uses to receive data.
2. Connection:
TCP Socket: TCP sockets establish a connection between the client and server before data exchange.
UDP Socket: UDP sockets do not establish a connection; they send and receive data without a connection.
3. Reliability:
TCP Socket: TCP provides reliable, in-order, and error-checked data delivery.
UDP Socket: UDP does not guarantee data delivery, order, or error checking.
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.
You can check it with the ping command from the command line in Windows. It is enough to enter it, with a space - the data of the proxy server (including the number of the port used) and press Enter. The reply message will tell you whether or not you have received a reply from the remote server. If not, the proxy is unavailable, respectively.
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.
It is a proxy that everyone can connect to. That is, it handles absolutely all requests without interacting with the traffic in any way, without monitoring its packets.
