Black Hole
May contain traces of nut
Absolutely.All except... this PC, which has a submask of "255.0.0.0", which, I presume is wrong to have?
Should I change it to "255.255.255.0"?
That's the problem with not "just" defaulting to DHCP everywhere: having to be careful... everywhere. DHCP sets the netmask too, which is why I recommend starting with DHCP and then only changing what has to be changed when going to manual.
