How long did scanning the entire IPv4 space take?
- NavinF 5y ago~4 hours on a 1G port, IIRC I’m sure you could do it a lot faster with a better CPU and 20% commit on a 10G port
- kkirsche 5y agoThat depends on the machine you are using. Tools like mass scan to locate open ssh ports and then testing them doesn’t need to take long if you have a beefy machine and pipe to the internet.
- chockchocschoir 5y agomasscan with the right setup (namely hardware + drivers but also connection obviously) can scan the entire IPv4 space (+ all ports) in ~5 minutes.
