If some of the IPs are blocked when you are renting a US server, the best way is to contact your server service provider or blocking agency to understand the reasons for the blocking, and take corresponding measures to unblock them according to their guidelines.
There may be many reasons why the IP address of the US server is blocked, including but not limited to the following:
Malicious behavior: If an IP address on the server is used for malicious activities, such as spamming, conducting cyber attacks, spreading malware, etc., this IP address may be blocked. Network service providers and blocking agencies will use various technical means to detect and block such malicious behaviors, and block relevant IP addresses to protect network security and prevent abuse.
Violation of network policy: If an IP address on the server is used to violate the network policy of the network service provider or other relevant institutions, such as violation of usage policy, violation of anti-spam policy, violation of intellectual property policy, etc., this IP address may also will be banned. Internet service providers usually formulate a series of usage policies to require users to use their services legally and compliantly. If users violate these policies, their IP addresses may be blocked.
Shared IP address: In a multi-IP server, multiple users may share the same batch of IP addresses. If one user's actions lead to the banning of the shared IP address, other users' IP addresses may also be affected and banned, even if they are not violating network policy or engaging in malicious behavior.
Misjudgment or abuse: The decision to block an IP address may result in a legitimate IP address being banned due to misjudgment or abuse. For example, a blocking agency may mistakenly mark an IP address as malicious or violating, resulting in the IP address of a legitimate user being blocked.
It should be noted that each network service provider and blocking organization has its own blocking policy and blocking mechanism, and the specific blocking reasons and unblocking procedures may vary from organization to organization.
In order to reduce the risk of IP being blocked for business. When you find that your IP is blocked, you can consider the following methods to solve this problem:
Contact server rental service provider
First of all, you can contact the service provider where you rented the server, report to them that the IP is blocked, and ask them to provide a solution. They may help you replace blocked IPs, or provide other solutions, such as changing server locations or configurations.
Check the reason for IP ban
It is very important to understand the reason for the ban of the blocked IP. You can check the ban notice of the blocked IP or contact the ban agency to find out the specific reasons for the ban. Sometimes, the reason for IP blocking may be due to spam, malicious attacks or other violations of network policies. Once you understand the reason for the ban, you can take appropriate action, such as cleaning the server for malware or configuring the server to comply with network policies.
Change IP address
If you cannot unblock the blocked IP, you may consider requesting the server service provider to change the IP address. Usually, the server service provider can provide you with a new IP address to replace the blocked IP. It takes a certain amount of time and operation, but it can help you solve the problem of IP being blocked.
