Local network device IP addresses - are these okay?

Hello.

Just set up my Core and I was wondering if it is normal for my device's IP addresses to be formatted like they are.  I am not a network guy, so this may be fine, but...

My old routers would always be something like 192.168.71.#.

All of my devices connected to the Core are x.y.#.#.  So I have some devices as x.y.20.2 and x.y.15.28.

First, is it okay that the first two are not 192.168?

Second, is it okay that the last TWO (and not just the last one) set of digits are different on the devices?  I'm not used to seeing the last two sets of digits be random like that on my own network.  Usually, it's only the last set of digits that differ.  I'm also not used to seeing anything but 192.168 to start.

Thanks for clearing this up for me.

(Side note:  any way to return to 192.168.x.y?)

Re: Local network device IP addresses - are these okay?

Hello user2665 The Core internal IP will always be 172.16.0.1 and CANNOT be changed. With the latest app versions for Android v1.22 / iOS v1.22.3  there is the ability to set static IP reservation by device which is done by changing the 3rd octet set in the 172.16.0.2 address for each device. https://support.norton.com/sp/en/us/norton-core-security/current/solutions/v118380605_core_en_us

If your devices are showing the 3rd AND last octets as being random your setup has something incorrectly connected and your provider device is assigning those IP addresses. Your external IP shown on your app should be what the normal IP was for your router as 192.168.1.2 or 10.0.0.1 for some provider routers. These are perfectly normal. If you have devices connected directly to the provider or personally owned router its internal routing will show separate IP ranges for each device in its DHCP capabilities. ONLY devices directly connected to the Core are protected by the core.

Re: Local network device IP addresses - are these okay?

Thanks to you both.  I have the Core connected directly to my TP-Link Archer CR700 modem/router but the Wi-Fi is completely turned off and no devices are connected to the modem except for the Core.

However, my devices are being assigned IPs with both the third and fourth octet being random.  They all connect okay, but I am getting addresses like

172.16.15.2 and 172.16.12.9.

Is this bad?

Re: Local network device IP addresses - are these okay?

I haven't seen that before. Is the TP link your provider device or personal router? Also what is the firmware version showing in your Core app? Thanks in advance.

Re: Local network device IP addresses - are these okay?

The TP-Link is personal, but it looks like it gets updates from and [some of it] is configured by my provider automatically.

When I installed the Core, it said it had the latest version and no download was needed during that step in the setup.  However, when I open Settings, it says "Firmware Version:  Not available".  What gives with this router?

Re: Local network device IP addresses - are these okay?

Thanks. The TP- Link is being used to get your internet service from your provider as I understand it. No provider device. If that is the case, do you get TV and VOIP through your provider? The Core and TP-Link should be in a NAT-NAT setup is that is the case. Meaning core Ethernet cable in one LAN port on the TP-link connected to the port on the Core with the globe icon. Keep your DHCP enabled on the TP-Link. If you can bridge the TP-Link AND do not have TV/VOIP coming from your provider to the TP-Link DHCP should be disabled in that device so it will function as a pure gateway.

As for firmware version showing not available that is a known issue at the moment Norton is working on.

Re: Local network device IP addresses - are these okay?

Thanks for all of your great help.  I do not have TV and VOIP through my internet provider (I have other companies) so I disabled the DHCP server on the TP-Link modem.  I already have the Core connected to the modem as you stated.  Should I also disable the DHCPv6 Server on the modem as well?

Re: Local network device IP addresses - are these okay?

User2665 I would disable it and recheck all your device IP assignments to see whether they change. If they do this is the root of the IP issue.

Re: Local network device IP addresses - are these okay?

Okay, so I disabled DHCPv6 also and could no longer access the internet from any device.  I couldn't access the modem anymore either, so I reset the modem to defaults and then changed the modem to "bridge mode".  Then all of my Core-connected devices all have the third octet change but no other octets, as designed (I believe).  So I guess the problem is solved.  Thanks for your help.

Re: Local network device IP addresses - are these okay?

That's great. In my previous post we suggested setting the modem in bridged mode. Glad that was the solution after doing so and rebooting your modem. Glad to assist. Please mark the thread as solved if indeed you believe it has as appropriate. Have a great week, AND, enjoy the Core. Its an awesome product.

Cheers
