0Eero allocated two Subnets in Automatic mode
When DHCP is in automatic mode, the devices connected to Eero are getting IPs in both 192.* and 10.* ranges.
This is a problem for the devices which cannot find each other across the subnets.
Is this normal? I assumed that in automatic mode eero will still use one subnet mask.
Is the only solution to switch to manual DHCP?

I’m assuming you have the guest network enabled? Any devices connecting to the guest network would be in a different subnet.

Guest is enabled, but the devices are not using it. They all log in to the main network.

Is this a good configuration?
Manual IP
IP address prefix 192.168.0.0
Subnet IP 192.168.0.0
Subnet Mask 255.255.0.0
Starting IP 192.168.5.1
Ending IP 192.168.15.254
We will use 192.168.0.1 - 192.168.4.254 for static IPs.

why are you subnets so large? /16?

We have about 20 devices permanently connected to the main network, and about 100 connected to guest at a time (customers come and go). Don't want to run out of IPs, and I don't know what is Eero's policy of releasing them.
Is there any downside for /16? I can use /20 instead. Probably even less.

I don't know if there is a downside to that other than possible IP conflicts if someone on your network fires up a VPN to something. I would go with something smaller than like like a /24 which still gives you more than enough IP's (254 usable IP's). I don't think the guest network is configurable, is it? If it is, I really need to know how to do that. I ran into some issues since the eero pro system automatically carves up separate IP segments for the guest network and I need more control of the IP segments on the guest network.
If my observations are correct, your main network is configured for /16 and doesn't have anything to do with the guest network...seems that you trying to address the concern of running out of guest network IP's and those are automatically set at /24 segments from everything I see.
