Basic Proxies Knowledge

In the face of DDoS proxy IP attacks, the following measures can be taken to effectively defend:Traffic Scrubbing: By monitoring and filtering the traffic entering the network in real time, malicious traffic is identified and isolated, and only legitimate traffic is sent to the target server. This can be achieved through professional DDoS cleaning equipment or cloud services.Use Content Distribution Network (CDN):CDN distribute users’requests by caching website content to servers in different locations around the world, reduce the pressure on the main server, and has the flexibility to expand.Load balancing: Use a load balancer to distribute user requests to multiple servers, improve the system's ability to withstand pressure, and dynamically adjust resource allocation according to the change of traffic load.Firewall and Intrusion Prevention System (IPS): Configure firewall rules to limit the traffic of specific IP addresses, ports and protocols, and use IPS to monitor network traffic in real time, analyze abnormal behavior patterns, and actively prevent potential attacks.Protocol and connection restriction: by configuring network devices or application servers, limit the traffic of specific protocols, and set restrictions such as the maximum number of connections, connection rate and request frequency.Strengthen network infrastructure: improve network bandwidth capacity and server resources, strengthen the protocol stack of server operating system and network equipment, and fix known vulnerabilities.Real-time monitoring and response: configure real-time monitoring tools and establish a response plan, including emergency contacts, communication channels and emergency response processes.Consider using professional DDoS protection services: Professional DDoS protection service providers have strong infrastructure and professional technical team, which can provide real-time traffic monitoring, cleaning and defense services. User's browser fingerprint is generated by client information: the user's browser information is collected by JavaScript, and a unique user ID is generated to lock the user's identity. Even if the attacker changes the IP, the user's identity can still be identified by the client information.Deploy secure accelerated SCDN: Secure Content Delivery Network (SCDN) can filter malicious requests and attack traffic, and is suitable for Web applications. It accelerates content transmission and protects websites through content caching, fast transmission and dynamic routing technologies.Other defensive measures: including but not limited to using Web application firewall (WAF), optimizing the use of resources to improve the load capacity of servers, enabling the anti-IP spoofing function of routers or firewalls, and using third-party services to protect websites, etc.Through the above measures, we can build a comprehensive defense system to effectively deal with DDoS proxy IP attacks. At the same time, enterprises should conduct risk assessment and security drills regularly, update and strengthen security measures in time, so as to improve the network's resilience and coping ability.

Overseas private IP and native IP are two different IP address types, and there are significant differences in their definitions, characteristics and application scenarios. Overseas private IP is usually an IP address associated with a specific geographical location or country provided by a specialized service provider. These IP addresses are exclusive and not shared with other users. They can be used to bypass geographical restrictions, visit websites in specific countries or regions, protect users' privacy and provide anonymous access. Overseas private IP has obvious advantages in protecting users' privacy, providing anonymous access and bypassing geographical restrictions, and is suitable for users who need these functions. Native IP refers to the IP addresses directly assigned to users by Internet service providers (ISP), which usually reflect the actual geographical location and network connection of users. Native IP provides a direct connection between user equipment and the Internet, so it is easier to be verified in security filtering and firewall settings, and is usually regarded as a safer option. Native IP address can also improve the security and trust of the server, which is suitable for scenarios that need to establish a direct connection with the Internet, provide reliable services and integrate various online services and tools. When choosing whether to use overseas private IP or native IP, users need to make decisions according to their actual needs and goals. If you need to protect privacy, provide anonymous access or bypass geographical restrictions, overseas private IP may be a better choice; And if you need to improve the security, trust, functionality and flexibility of the server, then native IP may be more suitable. Native IP has many advantages, such as authenticity, high-speed connection, geographical correlation, difficulty in being blocked, wide applicability, reliability and stability, etc. It can be identified by checking the WHOIS information of IP, performing reverse DNS query and testing the network delay and stability. Generally speaking, overseas private IP and native IP have their own unique advantages and applicable scenarios, and users should choose the most suitable IP type according to their own needs.

Proxy Host and Port are important concepts in computer network, and they play a key role in data transmission and network communication.  Proxy Host: A proxy host is a server that acts as an intermediary between the client and the target server. The request sent by the client first reaches the proxy server, and then the proxy server forwards it to the target server, and returns the response from the target server to the client. The proxy server can cache the requested content, and when other clients request the same content, they can provide it directly from the cache, which reduces the request to the target server and improves the response speed. Proxy servers can filter requests and responses, such as blocking malware, advertisements or inappropriate content. The proxy server can hide the real IP address of the client and provide a certain degree of anonymity. Allocate requests among multiple servers to optimize resource usage and response time. Proxy servers can control access to specific resources and enforce security policies. Connection Port (port): Port is a logical concept in network communication, which is used to distinguish different services or processes. Each network connection consists of an IP address and a port number, so that data can be sent to the correct service or application accurately. Different port numbers are used to identify different network services. For example, HTTP services usually use port 80, while HTTPS services use port 443. A server can run multiple services at the same time, and each service listens on different ports, thus allowing multiple network connections to be made at the same time. By restricting access to specific ports, you can increase network security. For example, closing unnecessary ports can reduce the risk of being attacked. Port configuration is a part of network management to ensure the correct operation and maintenance of network services. In practical application, the proxy host and the port work together to ensure the efficiency and security of network communication. For example, when a client wants to access a resource on the Internet, it may send requests through a proxy server. The proxy server listens on a specific port to receive these requests and forwards them to the target server.

IP location technology is a method to determine its geographical location by analyzing IP address, which plays an important role in network security, market analysis, advertising targeting and other fields. This technology can help identify the country, city and region corresponding to IP address, and even more detailed geographic information such as postal code, latitude and longitude. In the field of network security, IP location technology can be used for intrusion detection and defense, and potential intrusion behaviors can be found in time by analyzing network traffic and identifying IP addresses. In addition, it can also assist threat intelligence analysis, virtual private network management and network traffic analysis, help security teams track the source and behavior pattern of network threats, provide valuable threat intelligence, and guide the formulation and adjustment of security policies. However, IP location technology also has some challenges and limitations. For example, the dynamic allocation of IP addresses and the use of proxy servers may lead to inaccurate positioning results. In addition, privacy protection is an important issue, and it is necessary to give full play to the advantages of this technology while protecting users' privacy.  In order to protect personal privacy, users can take some measures, such as using virtual private network (VPN) to hide the real IP address, using proxy server as an intermediary to forward requests, or using Tor network to hide the IP address and online behavior.  In a word, IP location technology is a powerful tool, but the balance between accuracy and privacy protection needs to be considered when using it. With the continuous progress of technology, it is expected that IP geo-location technology will become more accurate and intelligent, bringing more possibilities and opportunities for network security and user experience.

Enterprises use IP proxy to protect their e-mail system mainly to enhance security and improve the efficiency of e-mail. The following are several key protection measures provided by IP proxy for enterprises:  Anonymity: IP proxy hides the real IP address of enterprise server to prevent targeted attacks, such as DDoS attacks, and also protects the real identity of users from being revealed.  Encryption: The proxy server can encrypt the whole network traffic, which increases the protection of e-mail content and prevents sensitive information from being intercepted and tampered with. Preventing spam: Using proxy IP to send mail can avoid being judged as a spammer by a mail service provider because a single IP sends a large number of mails, thus improving the arrival rate of mail.  Network security: The use of proxy IP can reduce the need for direct connection to the Internet. As an intermediary, proxy server can filter out malicious requests and attacks and improve the defense capability of the website.  Data protection: IP proxy service providers usually abide by strict data protection standards, such as ISO 27001 information security management system, to ensure the safety of user data.  Mail encryption: In addition to using proxy IP, enterprises can also adopt mail encryption technology, such as PGP, to ensure the security of mail content during transmission and prevent unauthorized access. Improve efficiency: Proxy IP can support multi-thread mail sending, effectively improve the efficiency of mass mailing, and at the same time support automatic switching and disabling of IP that cannot be sent to ensure the continuity of mail sending. Through these measures, enterprises can ensure the security of e-mail system and the reliability of e-mail, thus protecting enterprise communication from network threats.

The importance of multi-account management and proxy is reflected in many aspects, including avoiding platform restrictions and detection, protecting users' privacy and security, improving network access speed and stability, and realizing multi-regional business layout. First of all, using proxy IP can avoid IP addresses being associated when managing accounts on multiple network platforms, and reduce the risk of account being blocked. Proxy IP provides IP addresses in different geographical locations, which helps to circumvent the platform's restrictions on the number of registered or logged-in accounts under the same IP address.  Secondly, proxy IP helps to protect users' privacy and security. By hiding the user's real IP address, the third party cannot directly track the user's real identity and location, which increases the security of users when using multiple accounts. In addition, proxy IP can improve the speed and stability of users' network access by optimizing network connection and routing. Proxy servers usually have faster network connection and more stable service quality, providing users with a smoother network experience. For users who need to do business in different regions, proxy IP can provide IP address resources on a global scale, so that users can make business layout and strategy according to market demand and laws and regulations in different regions. At the enterprise level, the security of multi-account management is particularly important. For example, when a large enterprise goes to the cloud, it will establish a multi-account system according to different business lines, projects or usage scenarios, so as to realize the independence of cost settlement and operation and maintenance management, and at the same time reduce the risks caused by excessively broad permissions under a single account. The use of proxy IP can also improve work efficiency, especially in data collection, crawler tasks, privacy protection and security. When choosing a suitable proxy IP provider, we need to consider its stability, speed, IP number and distribution, and pay attention to privacy protection measures.  In addition, multi-account management tools, such as AdsPower fingerprint browser, ensure the independence and security of each account by generating independent browser environment and device fingerprints, effectively improve the proxy operation effect and reduce account risks. In terms of short video IP creation, multi-account management can help the team to operate each account more efficiently, and make fans "addicted" to the content by strengthening the IP account staffing. To sum up, multi-account management and proxy are important tools to improve the efficiency and security of network activities, and both individuals and enterprises can optimize account management strategies through rational use of these tools.
