Does he only know how to save successfully scanned files?

sudo masscan -p 11434 60.1.1.0-60.1.1.255 --rate 1000 -oL result.txt

I tried the IP address in the file, but the specified port was not opened. Why is this? Did he also save the scanned IP address inside? Not just successful?

try :

masscan 60.1.1.0/24 -p11434  --rate 1000 -oL result.txt

masscan 60.1.1.0-60.1.1.255 -p11434  --rate 1000 -oL result.txt
