What is the purpose of alternate IP addressing?

The purpose of alternate IP addressing is to allow devices to have a secondary IP configuration. This feature is particularly useful in scenarios where a device needs to be part of more than one network at a time or in situations where a device might not have access to its primary network temporarily. By configuring an alternate IP address, a device can maintain its connection to another network, ensuring greater flexibility and reliability in network communications.

In practical terms, having an alternate IP address can facilitate smooth transitions between different network environments, assist in redundancy, and improve overall connectivity options without requiring constant reconfiguration of primary settings. This functionality is particularly beneficial in environments where devices are frequently moved between different subnets or in cases of temporary network outages.
