Scanning local ip space

I have been curious lately on how I can go about finding local machines in my area. I have been messing around with Wireshark and AngryIP, but I am not too sure of my results. I understand the results I receive in Wireshark, but my real question is with AngryIP.

How do I know what IP range to use? Where do I start? Any helpful tips on scanning local networks?

Start with 0.0.0.0/0, you'll be surprised with the results thumbs up

Edited: You have 515 points in HBH and you don't know what IP range to use in your local network? :|

It's best not to poke other people's machines until you actually know what you're doing. I would suggest setting up a network of VMs (as small as one or two + your host) and then pointing tools at them to get a feel for how things work.

As for actually conducting a local scan, I would start by enumerating everything in your IP/Subnet range and throwing nmap (or angryIP, I guess) at it. An ARP scan can also quickly enumerate everything that's choosing to show itself on your local subnet.

Sad I know. I never really know where to begin so I just sort of learn things when they come to me. Web exploitation is the first area I started to learn and it is the only one in which I have made much progress at all.

Thank you both for your help!

If you really want to learn more about TCP/IP networking I would suggest to have a look on some Cisco CCNA Routing/Switching or Comptia Network+ articles or videos.
