Use the route command on Linux to view and delete entries from the routing table. To remove a route for a specific subnet, use the command:

route del -net DST netmask MASK

replacing DST with the subnet IP and MASK with the subnet mask. For example, to delete a route for the subnet 169.254.0.0/16, run the command:

route del -net 169.254.0.0 netmask 255.255.0.0

Being in networking, I frequently need to determine subnet sizes, mask sizes, and address ranges. While I could do this all in my head, I like to use the handy Online IP Subnet Calculator. You can set any number of subnet parameters and get the resulting address range and broadcast address.
