Orbi RBR850 IP Address reservations and DHCP address range

Im looking for direction related to using address reservations, and how to set the DHCP address range.  I have an Orbi RBR850 and 2 satellites RBS850, a Synology NAS, and about 20 other devices attached.(Laptops, iphones, Directv, etc.).

 

Assuming all devices are setup for DHCP and not fixed IP:

 

1) Should I set the IP address range for DHCP to start at 192.168.1.20, and reserve IP addresses for NAS and other critical devices between 192.168.1.2 and 192.168.1.19, or does the DHCP range need to include the all of the IP addresss including the reserved IP addresses?

 

2) Should the Orbi satellites receive reserved IP addresses?

 

3) Does it matter if devices on reserved IP addresses are plugged into an Orbi  satellite in some circumstances?

  • I use a "banded" approach for IP reservations for my Orbi, NAS and about 100 other devices....

     

    Different types of devices reside on different IP address Bands.... as an example:

     

    Router:  192.168.1.1

    Satellites:   Assigned IPs at .2, .3, .4

    Statically assign TV's at .20, .21, etc

    Statically assign Computers at .30, 31, 32, etc

    Statically assign SONOS at .50, 51, etc

    Statically assign printers and other special devices (NAS, surveillance cameras, etc) at .80, .81 etc

    Begin DHCP reservations at say .100

     

    This way you know anything assigned DHCP has not been categorized yet and is a "new" join to network.

     

    Note that just because you start DHCP at .100 you can reserve IPs outside of that range.

     

    Seems like a pain to go through all of this, but I assure you a well thought out IP distribution will pay huge dividends later.

     

    Of course after doing this, you will want to backup your Orbi config.

    Yes you can do that. I use a default IP address pool range of .100 to .200. Anything on ether side of this pool range can be used for static assigned devices. I would set static IP devices like, NAS, Controllers, Cameras, printers and anything that doesn't need much router management, set these devices to static outside the IP address pool 

     

    2) Should the Orbi satellites receive reserved IP addresses?

    You can set up reservations for the RBS ON the RBR. 

     

    3) Does it matter if devices on reserved IP addresses are plugged into an Orbi  satellite in some circumstances?

    No. The RBS are just pass thru.

      An IP reservation as I understand it while having similarities to a static IP address, still has the individual device set as DHCP. So when using IP reservations for some devices, should they be included in the range of IP addresses (starting IP address range) or should they be excluded from the range of addresses in the DHCP pool?

        You can reserve IP addresses outside of the range of DHCP assignments.
