You haven't included which system you're on or which tool-set you're using, but the two most common commands for managing the routing tables are the route and ip commands.

Here is how you might remove the route by using the route command (from the net-tools package):

route del -net 122.252.228.38 netmask 255.255.255.255

And here is how you might delete the same route using the ip command (from the iproute2 package):

ip route del 122.252.228.38/32
