I've noticed that both a router and individual devices on the network can be used to define a static IP address.

For example, my NAS can be set to have a static address (e.g., and the (DHCP on) router also can be set to reserve this address for that particular device, yet both settings appear to do the same job.

Is there any benefit in setting both devices (sort of doubling up), or just using one of them (and which one)?

If you set a static address on the device it won't look for DHCP when starting.

I personally prefer to use static DHCP mappings for devices that require a static address. It's just simpler to manage overall if there are a lot of them.

At the end of the day each method does the same thing it's just what you prefer. Some times though DHCP is required to include things like option 66 for example - not likely in the home network though.

I would recommend a DHCP mapping as its easier to manage. I use that at work for things like printers, security cameras etc. Not a good idea for a critical system though as it will go offline if the DHCP server fails.

IPv6 SLAAC is where its at, every device by its nature has a unique address.
