There are several reasons why dedicated IP is considered advanced and secure:

Exclusivity: Dedicated IP means that each user has a separate IP address and is not shared with other users. This exclusivity ensures that the user's network activities will not be interfered with or affected by others, providing higher security and privacy protection.

Preventing DDoS attacks: Dedicated IP can effectively prevent distributed denial of service (DDoS) attacks. In a shared IP environment, an IP address may be shared by multiple users, which increases the risk of DDoS attacks. Dedicated IP can reduce the possibility of such attacks because each IP address is only assigned to one user.

Data privacy protection: Dedicated IP can protect the privacy of user data. In a shared IP environment, an IP address may be shared by multiple users, which may lead to the risk of user data leakage. Dedicated IP can ensure that each user's online behavior is protected and data leakage is avoided.

To choose a better online proxy, you can consider the following aspects:

IP quantity: Choose a proxy service provider that can provide a large number of IP addresses, so that users can ensure that there are enough IP resources to choose from, and avoid the use effect affected by insufficient IP resources.

Speed ​​and stability: The quality and speed of proxy services are crucial to user experience. Choosing a proxy service provider with fast speed and high stability can ensure that users will not encounter frequent disconnection or slow speed problems during use.

Security: The security of the proxy service provider is also one of the factors that need to be considered. Make sure that the proxy service provider has strict security measures and privacy protection policies to protect the user's network security and privacy.

Customer Service: Choosing a proxy service provider that provides good customer service can help users get timely solutions when they encounter problems during use. Understanding the customer service quality and response speed of the proxy service provider is also an important part of choosing a good proxy.

In summary, choosing a relatively good online proxy requires comprehensive consideration of multiple aspects, including the number of IPs, speed and stability, security, and customer service. By carefully evaluating and comparing the pros and cons of different proxy service providers, users can choose a high-quality proxy service provider that meets their needs.
