Frequently Asked Questions
What's the difference between a static IP and DHCP reservation?
A DHCP reservation assigns the same IP automatically each time the device connects — easier than manually configuring the device's network settings.
Can two devices have the same static IP?
No. Duplicate IPs cause conflicts. Make sure each reservation uses a unique address.
