Router - IP address range

Question

Dealing with a new router to replace the current internet provider modem/router for a small business. But the business has about 6 IP addressed printers, plotters, and scanners.

I normally use the 192.168.1.nnn address range when install new routers. However, some of these devices will be a pain just to figure out how to change the IP address.

Can I use the modem/routers 10.1.10.nnn address space so that none of the IP addresses need to be changed? I know the modem needs to keep the 10.1.10.1 address (I guess) so I would start the DHCP address range at .2-250.

Is there a issue with this that might cause it to crash?

Thanks!

Your description wasn't that clear but you can use whatever IP range you prefer.&nbsp;
And devices shouldn't need to get their own IP address. when they connect to the new device, it assigns them an IP address.&nbsp;

Thanks for answering.&nbsp;I'm replacing the current modem/router combo (from internet provider) with a newer router.The scanners, printers, and plotters all have static IP addresses.&nbsp; This equipment was setup by a the respective vendor.&nbsp; Note 2 of the plotters have built-in laptops where the images are stored and processing for printing.&nbsp;I would rather not have to change the static IPs on these devices/laptops.&nbsp;&nbsp;&nbsp;My question is can I use the current 10.1.10.nnn, with 10.1.10.1 being the modem/router, address range?&nbsp; I use the 10.1.10.1 to login to the Arris modem/router.&nbsp; So I would think I need to start the address space with .2 with.&nbsp;Thanks for the help.&nbsp;Darryl

It still isn't that clear to me what you are doing, with that mix of IP addresses 10.1.10.1 and 192.168.1.1

&nbsp;

What were those fixed IP addresses? 10.1.10.XXX or 192.168.1.XXX?
&nbsp;
If the IP address of the current modem/router combo? 10.1.10.1, is that what the devices were fixed to work with?

&nbsp;

By default, your R7000 will try to squat on an IP address of 192.168.1.1
&nbsp;
That isn't likely to be much use to devices with addresses fixed to work to the 10.1.10.1 router.
&nbsp;
Putting the new router on 10.1.10.1 might be the easiest option.
&nbsp;
If you want the R7000 simply to spread the wifi, then using that in AP mode would let the existing modem/router manage the network.

The current router is the modem/router from the internet provider.&nbsp; It is set to 10.1.10.nnn range with the 10.1.10.nnn range for the network.&nbsp;I'm replacing the internet provider's router with a new router.&nbsp;Can I setup the new router with the same 10.1.10.nnn range?&nbsp; &nbsp;Or is 10.1.10.nnn only used by internet providers?&nbsp;All static devices and dynamically assigned devices are on the current IP range of 10.1.10.nnn.&nbsp;The current modem is assessed by the 10.1.10.1 IP address (Comcast Xfinity modem/router).&nbsp; That is why i was thinking I need to start the IP address space at 10.1.10.2 thru 254.&nbsp; But removing the IPs used by static devices (which is 5 thru 30).&nbsp; Thats easy.&nbsp;Thanks for the help.&nbsp; Hoping I'm making this clearer.&nbsp;&nbsp;D

Ya you could use same IP address string.&nbsp;
I recommend setting the range to .100 thru .200. So you have room on either side for static IP addressed assigned devices.&nbsp;
