no dns on modem

@XfinityBenny​ I am a Linux user, and was in system administration for a number of years. I used the command

      nmap 10.0.0.1/24

to obtain the listing of devices attached to the local network. The command polls the network command device to report the device information of all the connections. The command returns:

Starting Nmap 7.93 ( https://nmap.org ) at 2024-05-17 10:02 EDT

The listing shows two of the devices on the network, first is the network channel with all the services available, but there is no line for the device name which should be returned by the DNS. Likewise, the second device that has a name "PiAudio" does not have a listed name. It should be in line 2 of the listing after the IP address. This tells me the internal DNS does not provide the device names. I am able to check that the channel has the proper name information by using the browser interface to access to 10.0.0.1. My question is why doesn't the request show up in my network request?

That's an interesting question, @user_3omh51. If your modem is being managed through the Xfinity app, it could impact the results on the browser interface. Most of the admin functions are directed to the Xfinity app if you have one of our newer gateways, like the XB7 or the XB8.
