IP Address Change, Model No. 6129-100-NAS, Firmware Version V1.0.0.84
On 09/05/2023 I removed my Netgear Wi-Fi Router Model No. R6129-100-NAS and my Arris Cable Modem as my cable company, Cox Communications , gave me an all-in-one Cox Panoramic Wi-Fi Gateway Router and Cable Modem. I had it installed for three days and due to many issues with it, I uninstalled and reinstalled my previous devices. After reinstalling, everything worked and still works well. The only thing I’m concerned with is the fact my IP addresses changed. They used to be 192.xxx.x.x or xx. My new IP addresses are now 10.xx.xx.x or xx. I am leaving out the other numbers for security purposes. Why did this happen and is it legit?
Re: IP Address Change, Model No. 6129-100-NAS, Firmware Version V1.0.0.84
The address change is due to the NETGEAR router detecting another router on your network. Make sure the Cox gizmo is set to bridge mode (if possible), or you'll be in a double NAT situation where you'll have 2 LANs that can't talk to each others.

Thank you for the reply. I don't think your answer applies as I am not using the Cox Panoramic Wi-Fi Gateway Router and Cable Modem. Using Netgear Wi-Fi Router and Arris Cable Modem,

What is that cable modem?
The exact number is not what matters, but the features it offers. If it is a modem/router then the answer from @microchip8 may well apply.
The fact that you get IP addresses of 10.xx.xx.x or xx suggests that you have two routers there. (No need to mask the full IP address, it is on your local network and no one can get at it from the outside world.) Your messages haven't told us what this Arris Cable Modem is.
I assume that your R6129 is really the R6120. If so, Don't expect ,much from it, the thing is limited to 100 Mbps.
According to Netgear's manual for this device, not always the most reliable source of information, the LAN and WAN ports support only 10BASE-T or 100BASE-TX. That makes it slower than many newer internet services and most modern network hardware. This may not matter to you, but be warned that it will hobble you if you ever sign up for faster Internet, anything over than 100 Mbps is a waste of your money with that router.

Michael,
Thank you for the reply. I am currently using the following: Netgear Wi-Fi Router Dual Band AC1200, Model No. R6120-100-NAS and Arris Surfboard DOCIS 3.0 Cable Modem, Model No. SB6183. These are the devices I had installed originally and after I uninstalled the Cox Panoramic Wi-Fi Gateway Router and Cable Modem. So my original IP Address was 192.xxx.x.x or xx. After uninstalling the Cox Router/Modem and reinstalling the Netgear/ Arris devices my IP Address now reads 10.xx.xx.x or xx. I am basically trying to comfirm this is all legit. Someone had mentioned that IP Addresses beginning with 10 are for businesses and I am not a business. Any help would be appreciated

Go back and tell "someone" that they don't know what they are talking about.
Most models in the Netgear range will explain that the 10.x.x.x address is a fall back when a router finds that there is already something on the 192.168.1.1 address.
I say most routers, but in the case of the R6120 we are talking about a router that is as basic as they get. Indeed, as I explained earlier, it is so basic that it is slower than most modern Internet services.

Standard cable only modem. No router. It has a 1000 Mbps Ethernet connection that is 10 times faster than your router can handle. If you pay for an Internet service faster than 100 Mbps, you are wasting money. (As I explained earlier.)
So my original IP Address was 192.xxx.x.x or xx. After uninstalling the Cox Router/Modem and reinstalling the Netgear/ Arris devices my IP Address now reads 10.xx.xx.x or xx.
You may see this because you have been changing things on your network. Devices have a habit of remembering old settings. To wipe those out, you can perform a "factory reset" on them.
