How to check whether the IP is a computer room IP or a residential IP

In the Internet era, we often need to know whether an IP address belongs to a computer room IP or a residential IP. This is important for network security, network management, and website defense. This article will introduce several simple and effective methods to help you query the type of an IP address.

  Method 1: Whois query

Whois query is a common method of querying IP information. You can query the registration information of an IP address through the Whois query tool. By checking the registration information, we can know whether the IP address belongs to the computer room IP or the residential IP.

1. Open a Whois query website, such as [whois.arin.net](https://whois.arin.net).

2. Enter the IP address you want to query in the query box and click the query button.

3. Wait for the query results to be displayed.

The query result will include the registration information of the IP address, such as the organization to which it belongs, contact information, etc. By analyzing this information, you can determine the type of the IP address.

Method 2: Query IP address range

Another method is to judge the type of an IP address by querying the IP address segment. Different IP address segments are usually assigned to different organizations or service providers. By looking up the allocation of IP address segments, we can determine whether an IP address belongs to the computer room IP or the residential IP.

1. Open an IP address segment query website, such as [ipip.net].

2. Enter the IP address you want to query in the query box, and click the query button.

3. Wait for the query results to be displayed.

The query result will display the organization or service provider to which the IP address belongs. By checking this information, you can preliminarily determine the type of the IP address.

Method 3: Ping command

The Ping command is a commonly used network diagnostic tool and can also be used to determine the type of an IP address. By using the Ping command, we can know the delay of the IP address, so as to preliminarily judge whether the IP address belongs to the computer room IP or the residential IP.

1. Open Command Prompt (Windows users) or Terminal (Mac or Linux users).

2. Enter `ping IP address`, where IP address is the IP address you want to query.

3. Press the Enter key to execute the Ping command.

4. Wait for the Ping command to finish and check the result.

If the delay of the result returned by the Ping command is low, it means that the IP address may be the computer room IP; if the delay is high, the IP may be the residential IP
