Which portion of the network layer address does a router use to forward packets?

Answer 1

In theory, the part that indicates the network. In IP networks, this is the first part of the IP address.

The size of the "network" part may vary; therefore, the router checks the address against different rows of its routing table; if, for example, a certain row specifies a network of 10.0.5.0 /24, that means that the first 24 bits must be compared, so the router will compare whether the first 24 bits match.
