ADSL dial-up VPS is a virtual private server connected to the Internet through ADSL dial-up. Configuring multiple IP addresses on the ADSL dial-up VPS can realize the use of multiple IPs. The specific steps are as follows:

1. Choose an ADSL dial-up VPS that supports multiple IPs: Make sure that the VPS provider you choose supports configuring multiple IP addresses on the ADSL dial-up server. Different providers may have different setup methods and limitations.

2. Obtain an additional IP address: Contact the VPS provider to obtain an additional IP address. Typically, you will need to purchase additional IP addresses and make sure your hosting supports the assignment of multiple IP addresses.

3. Configure the network interface: log in to your ADSL dial-up VPS, and configure the network interface to support multiple IP addresses according to the documentation or guide provided by the provider. This may involve modifying network configuration files, setting up virtual network interfaces (VLANs), or using specialized network management tools.

4. Assign multiple IP addresses: Once the network interface is configured, you can assign additional IP addresses to different services or applications. The exact method of assignment depends on the operating system and network configuration tool you use.

It should be noted that the network connection of ADSL dial-up VPS is usually not stable and reliable, and the speed is relatively slow. In addition, using multiple IP addresses may require additional configuration and management work, including firewall settings, routing configuration, etc. When selecting and using an ADSL dial-up VPS, please make sure to understand the relevant limitations and requirements, and consult the VPS provider or network experts for help if necessary.
