The IP protocol (Internet Protocol) is the foundation of the Internet. It defines how data packets are sent and received in the network, allowing devices between different networks to communicate with each other. The following are the basic principles of IP protocol to achieve network interconnection:
The principle of IP protocol to achieve network interconnection
Data encapsulation and grouping:
Data is divided into small blocks before transmission, called data packets or datagrams.
Each data packet contains two parts: header and data (payload).
The header contains information such as source IP address, destination IP address, protocol identifier, packet sequence, etc., which is used to guide the transmission of data packets in the network.
IP address and routing:
Each device connected to the network has a unique IP address that identifies the location of the device.
A router is a specialized network device used to transfer data packets between different networks. The router selects the optimal path based on the target IP address and transmits the data packet to the destination.
ARP protocol:
The address resolution protocol (ARP) is used to convert IP addresses into physical addresses (MAC addresses) for data transmission in local area networks (LANs).
Transmission control: Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are common transport layer protocols. TCP provides reliable and ordered data transmission, while UDP provides unreliable but efficient data transmission.
Error detection and correction: Data packets may be damaged during transmission. The IP protocol uses mechanisms such as checksum to detect and correct transmission errors.
Reasons why more and more people need proxy IPs
Privacy protection: Using proxy IPs can hide the real IP address, protect user privacy, and prevent being tracked or monitored.
Access to restricted content: Proxy IPs can help users bypass geographic restrictions and access blocked or restricted content. For example, access specific websites or services in certain countries or regions.
Network security: Proxy IPs can increase the security of accessing the network and prevent malicious attacks, phishing websites, etc.
Load balancing: Using proxy IPs can disperse access traffic to multiple IP addresses, reduce the load on a single server, and improve access speed and stability.
Web crawlers and data scraping:
When performing web crawlers and data scraping, using proxy IP can avoid being blocked by the target website and improve the efficiency and success rate of data scraping.
Common proxy IP types
HTTP proxy:
Suitable for web browsing and data scraping. It can be set in the browser or scraping tool to access the website through the proxy IP.
HTTPS proxy:
Supports encrypted HTTP proxy, suitable for applications that require secure connections, such as online shopping, banking transactions, etc.
SOCKS proxy:
Applicable to all network protocols and any application, such as web browsing, email, FTP, etc. SOCKS5 proxy supports higher security and flexibility.
Transparent proxy:
The user is unaware and directly forwards the request to the target server. Suitable for applications that do not need to hide the user's IP address.
Anonymous proxy:
Hides the user's real IP address, but the target server can detect the use of the proxy. Suitable for applications that require a certain degree of privacy protection.
Elite Proxy:
Completely hides the user's IP address, and the target server cannot detect the existence of the proxy. Suitable for applications that require high privacy protection.
By understanding how the IP protocol achieves network interconnection, as well as the needs and common types of proxy IPs, you can better select and use proxy IPs to meet different network applications and security needs.
