In business scenarios such as cross-border e-commerce, online games, and data crawlers, it is necessary to pay attention to network connectivity and security. IP addresses (especially public IPs) directly affect application performance and availability. This article will deeply analyze the definitions, technical backgrounds, and performance differences of ordinary IPs, premium IPs, and high-defense IPs, and combine typical scenarios such as cross-border e-commerce, game service providers, and crawlers to provide scientific selection suggestions and precautions.
Definitions and technical backgrounds of various IPs
Ordinary IP: also known as standard IP or regular IP, refers to a public IP address that only provides basic network connectivity, without additional optimized lines or built-in protection. Ordinary IPs are mostly used in general network communication scenarios such as general website hosting and mail servers. They have the lowest cost, but are easily affected by attacks such as DDoS and have low availability. When using ordinary IPs, it is usually necessary to deploy additional security measures such as firewalls at the application layer or network layer.
Premium IP: refers to an IP address that uses high-quality network lines to optimize the transmission of basic IPs. Premium IPs usually use high-quality paths such as Telecom CN2 GIA and operator multi-line direct connections to significantly reduce cross-border access delays and improve transmission stability. Cloud service providers call it "premium BGP IP", which has a dedicated line to avoid international export detours, thereby achieving lower access latency. Premium IP is particularly suitable for international businesses that are sensitive to network quality, such as overseas return visits, global acceleration and other scenarios.
High-defense IP: It is a type of IP address with built-in large-volume cleaning and DDoS protection capabilities. High-defense IP is provided by cloud security vendors or IDCs, integrating multiple protection mechanisms such as traffic cleaning, black hole routing, and access filtering. When a service is attacked on a large scale, the high-defense IP will divert malicious traffic to the cleaning node to ensure that the source station business is stable and available. As shown in the introduction of Shouyun's high-defense IP product, the high-defense IP provides massive cleaning capabilities, multi-line BGP and static three-line BGP defense paths, which can promptly meet the business needs of industries such as finance, games, and e-commerce.
Technically, premium IPs usually rely on multi-operator BGP interconnection or telecom CN2 networks to improve the quality of cross-border links; while high-defense IPs add security equipment and policies on the network side to detect and filter attack traffic. Ordinary IP and premium IP focus on transmission performance, while high-defense IP integrates additional protection functions on the basis of transmission performance.
Performance difference comparison
Network delay: Premium IP uses exclusive high-quality lines (such as CN2 GIA) to directly connect to mainland China and overseas nodes, so cross-border access delay is lower. Ordinary IP may pass through conventional international exits, with longer paths and higher delays. Although high-defense IP has traffic cleaning overhead, modern high-defense network optimization has little impact on normal access delay.
Bandwidth stability: Premium IP usually accesses multiple operator networks, with higher bandwidth redundancy and stability; ordinary IP can also cross operators, but there is no special optimization guarantee, and jitter or packet loss may occur during peak periods. When a high-defense IP encounters an attack, it will start traffic cleaning and speed limit strategies. Under normal circumstances, the bandwidth performance is close to the corresponding line, but once the protection mode is turned on, business continuity can be guaranteed.
Security protection capability: Ordinary IP does not have built-in protection function and is vulnerable to various network attacks. It needs to rely on additional security facilities for defense; Premium IP is mainly used to improve transmission quality and does not provide attack protection itself; High-defense IP is designed for large-scale attacks such as DDoS, and has intelligent cleaning, black hole routing and other capabilities. It can resist traffic attacks such as SYN flooding and UDP flooding to protect business availability.
Cost and cost performance: Ordinary IP has the lowest cost and is suitable for scenarios with low requirements for latency and stability; Premium IP is slightly higher than ordinary IP, but the return on investment is significant, especially in cross-border business scenarios, it can reduce latency and improve user experience; High-defense IP has the highest cost and is usually charged according to protection bandwidth. It is suitable for key scenarios with high business value and facing attack threats. Users should weigh business benefits and protection needs and plan investment reasonably.
Applicability in various business scenarios
Cross-border e-commerce: This type of business needs to ensure the access speed and data synchronization efficiency of overseas users. It is recommended to use premium IP (such as multi-line BGP/CN2 network) to shorten cross-border links, reduce latency, and improve page loading speed and stability. For e-commerce platforms with large traffic and obvious activity peaks, high-defense IP can be combined to ensure business availability when attacked maliciously; high-defense IP can meet the attack protection needs of the e-commerce industry.
Game service providers: Game servers have extremely high requirements for network latency and stability, and are also high-incidence targets of DDoS attacks. It is recommended that game service providers be equipped with at least high-defense IPs to use their large bandwidth cleaning capabilities to ensure the availability and fairness of the game environment. In terms of network optimization, you can consider high-quality IPs or multi-line direct connections to reduce player latency; ordinary IPs are not recommended for core game businesses because they are vulnerable to attacks and congestion.
Data crawlers: Data crawling tasks often require a large number of concurrent requests, which can easily trigger the anti-crawler mechanism of the target website. Crawler services generally do not pursue low latency or additional protection, but pay more attention to the number and strategy of IPs. The mainstream practice is to use a proxy IP pool and a dynamic replacement strategy to share requests through multiple IPs, thereby avoiding the ban of a single IP. At this time, ordinary public IPs or cheap dedicated IPs combined with an automatic rotation mechanism are more appropriate; the performance advantages of high-quality IPs and high-defense IPs are of limited help to crawler scenarios, but the cost is higher.
Price Tiers and Procurement Recommendations
Ordinary IP: The lowest price, can be purchased on demand or paid annually. Suitable for test environments, internal communications, or small businesses that are not sensitive to latency. Users need to configure their own protection strategies, such as using security groups or third-party firewalls.
Premium IP: The price is slightly higher than ordinary IP, usually billed monthly or by bandwidth. It is recommended to use it when cross-border business has high requirements for access speed. When purchasing, you can pay attention to the operator's line type (such as CN2 GIA, multi-line direct connection) and covered countries to ensure that the advantages of premium lines can be fully utilized.
High-defense IP: The price is the highest, usually billed according to protection bandwidth or attack peak. Before purchasing, you need to evaluate the business value and potential risks, and choose the appropriate protection level and cleaning capacity. It is recommended to consult the service provider to understand the protection threshold, billing model and cleaning effect, and reserve enough elastic protection bandwidth.
In summary, ordinary IP, premium IP and high-defense IP have their own characteristics, and should be scientifically selected according to actual business needs: ordinary IP can be selected for scenarios that pursue low cost and only require basic connectivity; premium IP should be selected for scenarios that pursue cross-border access quality; high-defense IP should be used for key businesses facing major security threats. By comprehensively considering network quality, security requirements and cost budget, users can select the most suitable IP solution for cross-border e-commerce, game services and crawlers and other businesses.
