Not able to run nmap scan on router

Question

I am trying to conduct nmap scan on my router. I find out my router using route command:

$ route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         _gateway        0.0.0.0         UG    100    0        0 ens33
link-local      0.0.0.0         255.255.0.0     U     1000   0        0 ens33
192.168.111.0   0.0.0.0         255.255.255.0   U     100    0        0 ens33

Now trying nmap but getting an error:

$ nmap 192.168.111.0

Starting Nmap 7.60 ( https://nmap.org ) at 2019-01-31 15:19 IST
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 0.07 seconds

Answer 1

Might not be the actual router address. To find router IP, try arp command:

$ arp

Then use that IP with nmap

$ nmap <ip address>
