Glad to see more open source options (I develop and maintain Scantron https://github.com/rackerlabs/scantron/) when it comes to network scanning! Appreciate your contribution to the community.

So you're not using nmap under the hood?

What's the largest IP space you've tested it on so far?

Scantron looks pretty awesome! liwasc isn't using nmap internally, the entire network scanner part (https://github.com/pojntfx/liwasc/blob/main/pkg/scanners/nod...) is <150 SLOC and the port scanner is <250 SLOC. Go has some really nice low-level networking APIs, especially when combined with `gopacket`.

I haven't really tested it on anything larger than /28 - it should probably work on larger ones as well though (it limits the maximum concurrent port & network scans so that ulimit etc. aren't an issue) :)

Nice...looking forward to seeing this evolve!
