Exactly! There are no= rules about what subnet range an ISP's gear will assign to DHCP device= s.

So (I believe) it becomes incumbent on OpenWrt = to be smarter than the ISP's router (shouldn't be hard) and pick a = separate subnet for its LAN & wireless interface. (Clearly, OpenWrt cou= ld default to 192.168.1= .0/24, but if that's that range the ISP is using, it could switch t= o 192.168.2.0/24. I= think that's all the flexibility that's required...)

I did exactly this= for a product that needed to create its own subnet inside a house.=C2=A0 I= t worked well at scale (>1M homes).


And then advertise a mDNS name to m= ake it easy for humans to connect. Who would notice?

Unfortunately, it can be ha= rd to convince browsers that you=E2=80=99re connecting to a local DNS name = instead of a doing a search.


- Newcomers wouldn't - they= 9;d just connect and configure as described in the Wiki
- Grizzle= d OpenWrt old-timers wouldn't notice either, because they will have set= their ISP device to use some other address range.

Any reason not to build this into OpenWrt? Thanks.
