If you just wanna scan a Single Port of a Particular Ip address then you can do that using the below command. Here I am scanning the entire network for the port 80 but you can put a single IP and it will work Perfectly. The advantage of scanning a single port is that it will save you some extra time especially when you are in a hurry.

nmap -p 80 192.168.1.1/24

Scan Multiple Port in Nmap Termux :

Do you know most of the time when you scan a Network and you find a device with open port 80 as well as 443 then it means that its a WebServer? So In the below command, I am gonna scan these two ports on my network, of course, I don't have a webserver running in my home so it won't show 443 port but if you scan it in a network where they have a webserver then it will show with this command.

nmap -p 80,443 192.168.1.1/24

 

Output :

In the below picture you can clearly see that it is only checking for 2 port and as the output, we can see in my routers Ip address port 80 is open but port 443 is not. And in my second device, Both ports are closed.
