Answer:
route add 170.122.0.0 netmask 255.255.0.0 reject.
Step-by-step explanation:
An IP address is an acronym for internet protocol address and it can be defined as a unique number assigned to a computer or other network devices, so as to differentiate each device from one another in an active network system. Thus, an IP address is typically used to uniquely identify each computer or network devices connected to the internet or network.
In order for packets to be sent to a remote destination, these three parameters must be configured on a host.
- Default gateway
- IP address
- Subnet mask
After a router successfully determines the destination network, the router checks the routing table for the resulting destination network number. If a match is found, the interface associated with the network number receives the packets. Else, the packets is dropped because it has been blocked on the routing table.
As a system administrator, if you want to block (reject) any packets from 170.122.0.0, 255.255.0.0. The command that should be used to block those packets is to use; route add 170.122.0.0 netmask 255.255.0.0 reject.
