Can you explain this? DNS resolves to an IP address, then that is scanned. What am I missing?

[doakes]

I think the DNS IPs are just example IPs to be scanned. You're not supplying a DNS to use for domain lookups. Using them in the example is perhaps confusing that there's some sort of DNS argument required.

It can be rude/unwise/dangerous (depending on the target) to run a scanner on somebody else’s public IPs.
