Private IP and shared IP

Private IP address refers to an IP address exclusively used by a user or website. This address allocation method has brought a series of advantages to users in Internet services. According to Verisign's statistics, websites that use private IP have more prominent requirements in SSL encryption and network security, which shows that private IP has obvious advantages in improving website security.  Because of its uniqueness and specificity, private IP address provides significant advantages in many aspects, especially for users who have high requirements for network performance, security and personalized service. Security enhancement: Because private IP is not shared with other users, the risk of being attacked is greatly reduced. According to Cisco's security report in 2023, the probability of DDoS attack on websites using private IP is 75% lower than that of websites sharing IP. In addition, the private IP also reduces the risk of IP blocking caused by the illegal behavior of other websites on the shared IP. Performance guarantee: Private IP can guarantee the stability and response speed of network traffic. A performance comparison study conducted by Cloudflare in 2023 shows that the loading time of websites using private IP is about 30% faster than that of shared IP websites, which is mainly due to the fact that private IP can avoid affecting its own performance due to the traffic peak of other websites on shared IP. SSL certificate compatibility: Private IP is the premise of installing SSL certificate, which is very important for websites that need encrypted data transmission. According to the statistics of SSL Pulse, worldwide, more than 80% of websites with SSL certificates use private IP. E-mail delivery rate is improved: Using private IP can avoid the influence of spam on shared IP. According to the data of SendGrid, the mail delivery rate using private IP is about 20% higher than that using shared IP. Custom DNS configuration: Private IP allows users to make more detailed DNS configuration, which not only helps to enhance the brand image of the website, but also provides higher flexibility and control. According to Dyn's report, websites using private IP are 50% more flexible in DNS configuration than shared IP. Shared IP address means that multiple users or websites share the same IP address. This way of using IP address has obvious advantages in cost and resource utilization. According to the report of Hosting Tribune, more than 70% of small and medium-sized enterprises choose to use shared IP for website hosting, which shows that shared IP is an economical and efficient solution in certain scenarios.  Sharing IP address shares the same IP resource through multiple users, which has obvious advantages in cost control and resource utilization efficiency, especially for users with limited budget or low requirements for network resources. Cost-effectiveness: Sharing IP reduces the cost of a single user by sharing the cost. A cost analysis conducted by DreamHost in 2023 shows that the cost of shared IP hosting is about 60% lower than that of private IP, which is an important consideration for individual users or small businesses with limited budgets. Efficient use of resources: Sharing IP enables hosting service providers to use server and bandwidth resources more efficiently. According to the resource utilization report of InMotion Hosting, the resource utilization rate of shared IP is about 40% higher than that of private IP, which helps to reduce energy consumption and cost. Wide applicability: Shared IP is suitable for most standard website hosting requirements, especially those websites with low requirements on security and performance. According to the data of Bluehost, more than 85% of small blogs and personal websites choose to use shared IP, which shows its wide applicability. Easy to manage: Sharing IP simplifies the management process of hosting service providers, because multiple websites can be hosted at the same IP address. This not only reduces the complexity of management, but also reduces the potential configuration errors. According to the report of WP Engine, the management efficiency of shared IP is about 30% higher than that of private IP. Private IP and shared IP have their own unique advantages and applicable scenarios, and users should make comprehensive considerations based on security, performance, cost and business requirements when choosing.  Private IP is very suitable for users who have high requirements for security and performance, such as financial service websites, e-commerce platforms, mail service providers and brand enterprises, by providing higher security, more stable performance, the ability to install SSL certificates, improving the delivery rate of e-mail and customizing DNS settings. However, the cost of private IP is relatively high, which is suitable for users with sufficient budget. Shared IP is an ideal choice for individual users, small enterprises, test and development environments, low-traffic websites and multi-site networks with limited budgets because of its cost-effectiveness, efficient use of resources, wide applicability and easy management. Although shared IP may have some limitations in security and performance, its advantages in cost control and resource utilization make it the first choice for many users.  Ultimately, the choice of private IP or shared IP depends on the specific needs and priorities of users. For users who pursue the ultimate security, high performance and personalized service, private IP is undoubtedly a better choice. For users with limited budget and low requirements for security and performance, sharing IP provides an economical and efficient solution. When making a decision, users should fully consider their own business needs, cost budget and control requirements of network resources in order to choose the most suitable IP address type.
