Can you map IP addresses?
For a static IP address mapping, you can choose to map each IP address individually, or you can import a CSV file with the IP address and name pair for each device. You can also export all of the IP address/name pairs in the Static IP Address Map list to a CSV file.
When should you use a static IP address within a subnet?
Static IP addresses normally matter more when external devices or websites need to remember your IP address. One example is VPN or other remote access solutions that trust (whitelists) certain IPs for security purposes.
