The IP address cleanliness of the US server can ensure the security of the US server and network, and the cleanliness of the IP address is generally affected by the presence of malicious activities, spam, malware and other bad behaviors. Determining IP address cleanliness can maintain network and server security, reduce the risk of malicious activities, and protect the security of user services and data switches. Before users rent a US server, there are many ways to judge IP cleanliness, and there are the following 8 common categories!

IP blacklist check

Using online tools or services such as Spamhaus or MXToolbox, you can check if a specific IP address is blacklisted. The blacklist usually includes IP addresses that are considered to be spammers, initiators of malicious activities, etc.

Malicious activity scanning

Use security tools and services to scan IP addresses for malicious activities, such as DDoS attacks and port scanning.

Domain name association

Check if the IP address is associated with a known malicious domain name. Some malicious activities may use multiple domain names associated with the same IP address.

Reverse DNS lookup

Perform a reverse DNS lookup to verify that the IP address is associated with a legitimate domain name. Some malicious activities may use the mirrored domain name to attack.

Flow analysis

Analyze the network traffic of IP addresses and observe whether there are a large number of abnormal network activities or traffic patterns.

Security intelligence data

Leverage a variety of security intelligence data sources, such as threat intelligence platforms, to obtain information about a specific IP address, including its history of malicious behavior.

Website scanning

If the server is primarily used to host a website, use a website scanning tool to check if the website is threatened by malware, vulnerabilities, etc.

Compliance check

Check that the server meets security compliance standards, such as PCI DSS, to ensure its security.

The judgment of the degree of IP purity is a complex process, to be considered comprehensively, when managing or owning a server, security review and monitoring should be conducted regularly to protect the security of the server's muddy center activities, and it is also necessary to ensure in advance that the U.S. server is configured with a clean IP address.
