172.18.50.1 is a next-hop address tied to a different route entry in the table and does not correspond to the best-matching route for 10.10.100.0/24.

192.168.10.0 is formatted as a network address rather than a valid unicast next-hop (gateway) address and would not appear as a via address in a route entry.

172.18.1.1 is the next-hop address associated with the routing table entry that best matches the destination 10.10.100.0/24 using the longest prefix match rule. Cisco IOS selects the route with the most specific subnet mask among all matching entries, and the entry pointing to 172.18.1.1 represents that best match for this destination.

172.18.60.1 is the next-hop for a different destination network and does not match the routing entry for 10.10.100.0/24.
