Static IP address or reserved IP address?
Hello:
I have a new R7000 router and a new IP security camera system. The cameras record to a NAS (WD MyCloud) on the same network, after the IP address of the NAS has been input to the camera setup. The problem arises when we have a power outage - when the power comes back up, the router assigns a new IP address to the NAS and the cameras can no longer find it so they stop recording. I was thinking of setting the NAS up with a static IP address but then read that I can also use a "reserved" IP address with the R7000. Will this work (ie when the router restarts, will it keep the old NAS IP address?
Thanks.
It has the same end result. It allows you to manage the device from a central place (router), rather than having to set up a static IP in the device, as well as making sure the router doesn't hand it out to another device.
Most devices by default use DHCP (or in simple terms, get IP address automatically).

Yes, you would set up your DHCP range to include only a subset of your network, perhaps 128 addresses, and then set an IP reservation tied to the MAC address of the camera system, using an IP address that is outside of the DHCP range. This guarantees that your camera system will always get the same IP (unless you replace it and it has a different MAC address), and no other device will accidentally get this IP from DHCP.
Thanks. Actually, the cameras aren't the problem (they have an automated DDNS through the manufacturer's cloud), it's the NAS that's the problem. How about the "reserved" IP address option in the R7000?
My devices keep the same IP using "reserved" IP addresses. I did give my printer a static of .200 I did this by limiting the DHCP server to .2~.199 IP range and then setting the printer IP manually to .200
Thanks. So the "reserved" address approach results in the same thing? (It's just quicker and easier than going through the static IP address setup)
