[c-nsp] Network Address Response

[Ray Burkholder]

I was wondering the reasoning for routers/switches to respond for the
network portion of an ip-address range.

For example, a router interface A with 10.0.0.1/30 and interface B with
10.0.0.5/30.

Generate a ping from a device several hops away on the A side to the B side
network address of 10.0.0.4.  The router will respond with an echo reply
with an address of 10.0.0.1.

Is this expected behaviour?  And the reason?
