In the User Datagram Protocol (UDP), dynamic ports are assigned using a process called ephemeral port allocation. UDP is a connectionless protocol, which means that it does not establish a dedicated connection between the sender and receiver, as the Transmission Control Protocol (TCP) does. Instead, UDP sends data packets directly to the destination, and the receiver is responsible for acknowledging receipt or requesting retransmission if needed.
In UDP, both the sender and receiver have a pair of ports: one for the source and one for the destination. The source port is assigned by the sender, while the destination port is assigned by the receiver. When a connection is established, the sender assigns an ephemeral port to itself and sends the data to the destination port specified by the receiver.
The assignment of dynamic ports in UDP is typically managed by the operating system. The process generally follows these steps:
1. Ephemeral port allocation: The operating system maintains a pool of available ephemeral ports, which are typically in the range of 49152 to 65535. When a UDP connection is initiated, the operating system assigns an available ephemeral port from this range to the sender.
2. Port reuse: Once a UDP connection is closed, the ephemeral port is returned to the pool of available ports. This allows the port to be reused for subsequent connections, ensuring efficient use of the limited range of high-numbered ports.
3. Port randomization: Some operating systems implement port randomization to prevent certain types of denial-of-service (DoS) attacks. In this case, the operating system may assign an ephemeral port that is slightly higher than the requested port, adding a small random offset to the port number.
4. Destination port assignment: The destination port is assigned by the receiver and is typically determined by the application or service that the receiver is running. The destination port can be a well-known port (below 1024) or a registered port (1024-49151), or it can be a dynamic or private port (49152-65535).
In summary, dynamic ports in UDP are assigned using a combination of ephemeral port allocation and destination port assignment. The process is managed by the operating system and is designed to ensure efficient and secure communication between devices.
HTTP proxies are used for surfing the Internet and working with social networks. However, when using this type of proxy, the user's IP address remains unprotected. At the same time, the connection speed remains high.
SOCKS proxy are designed to use programs and visit sites anonymously. Also this type of proxy allows bypassing the resources with proxy-server protection.
To sum up: SOCKS proxies are a more advanced development compared to HTTP. However, to use SOCKS, you must know how to configure your browser and use special utilities.
In the messenger settings, go to "Data and storage" and then, in the "Proxy settings" section, click "Add proxy". You can see whether a proxy is connected in Telegram by the presence of the shield icon located in the top menu bar.
Create the first profile by specifying its name and selecting the desired configuration. The configuration is a non-repeating combination of different versions of the operating system and browser. After setting the language, open the "Network" tab and select the type of proxy (socks5 or https). Now it remains only to fill in the data in the highlighted fields to complete the installation of the proxy.
To enable proxies in your MacBook, you need to go to "System Preferences" (from the "Apple" menu), then open "Network", then - specify the type of connection you are using. Then select "Advanced Settings" (can be named as "Advanced"), then click on "Proxy". And then - either set the parameters manually, or specify a configuration file.
