Greetings all netsperts;

I've purchased a new 3d printer which is factory equipt with klipper.

So the questions  are:
What do I need to change in my network config on this machine so I can ping
all 65536 address of the 192.168 block of ipv4 address?

You might try nmap. But who knows -- perhaps the printer is civilised and

  - waits for a DHCP to assign it an addres
  - gives itself one of those APIPA addresses (169.254.x.y)
    you love so much ;-)
  - comes up with a link-local IPv6

all of which would be RFC compliant

.
And less likely to find a home in the local environment than a plain old 192.168.yy.zz address I'd think. They who do that have so far stuck to 192.168.0 and 192.168.1 addresses.

Will changing the CIDR, presently /24 to /16 be sufficient?

...you mean: your netmask? You would have to, if you want to
have a route to all those addresses.

Another thing I would do: start tcpdump, then switch the
printer on, and watch what happens in the net.

A possibility I hadn't considered yet, but that might need the CIDR changed also.

Cheers
