Why are two IP addresses within the same subnet unable to ping each other?
be flag

I was setting up ip addresses between two devices and I noticed something odd. I feel like I am missing an important fundamental here:

Device A:
Device B:

if I set up the IP like this, then A and B cannot ping each other

However, if I do
Device A:
Device B:
Device A:
Device B:

Then A and B can ping each other just fine. ...

networking default gateway, default route
ua flag

in ipv4 cidr notation you can have an ip address like

it's expanded to

network  :
first ip :
last ip  :
netmask  :

That means I have a usable ip range from on this subnet.

would be the default gateway for this subnet?
