Local DNS for Orbi CBR40

Hi Community,

I have a pile of devices that connect to my Orbi and get an ip address assigned via dhcp.  I'm expecting these names to resolve from other devices on the same network.  My desktop can't resolve the names of other local devices using the orbi as a dns server.

 

For instance my Pi3 has this in its ifconfig

wlan0: flags=-28605<UP,BROADCAST,RUNNING,MULTICAST,DYNAMIC> mtu 1500
inet 192.168.1.102 netmask 255.255.255.0 broadcast 192.168.1.255
ether b8:27:eb:9c:09:43 txqueuelen 1000 (Ethernet)
RX packets 1672422 bytes 2409965083 (2.2 GiB)
RX errors 0 dropped 28 overruns 0 frame 0
TX packets 790026 bytes 66203101 (63.1 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

 

It can't dns resolve my desktop

osmc@osmc2:~$ host -v DESKTOP-FBLJ3I6
Trying "DESKTOP-FBLJ3I6"
Host DESKTOP-FBLJ3I6 not found: 3(NXDOMAIN)
Received 108 bytes from 192.168.1.1#53 in 52 ms

 

and vice versa my desktop can't find the pi3, or any other device on the network by name

>nslookup
Default Server: UnKnown
Address: 192.168.1.1

> osmc2
Server: UnKnown
Address: 192.168.1.1

*** UnKnown can't find osmc2: Non-existent domain

 

and its on the same wifi network

    Maybe that loopback is not supported on the CBR40...

  • Its possible the answer is adding .local to things.   Can someone else confirm?

     

    ping MacBook-Pro.local for instance works, is that domain configurable?
