Eggstoi Posted January 15, 2021 Share Posted January 15, 2021 Hey there, I am looking for all IPs with one special open port, for example 8001. So i use nmap like that to get them: nmap -Pn -p 8001 -iL ip-ranges.txt -T3 --open But this scan is doing so many things, which I maybe don't need: Parallel DNS resolution of 4096 hosts. Timing: About 26.49% done; ETC: 07:51 Can somebody give me maybe some command parameters which make this scan faster? Quote Link to comment Share on other sites More sharing options...
