Is there away on macbook to find all ip addresses on a network that i am connected to?
Is it your network, or someone else's?
it is my network.
If it's an AirPort device, launch the AirPort Utility and click on the device. That will give you a list of the wireless clients connected.
no not a airport device. All hard wired network. needing to find the list of all computers/devices on the network
You can install nmap, then run something like "nmap 192.168.1.0/24" to scan the entire IP range.
You can also run "arp -a" to see a list of current ARP entries, though this may not show the entire network.
do you run nmap in terminal ?
Yes, just run that command in the terminal and it will show you a list of computers on your network. There is also a GUI for nmap called Zenmap, but I have never used it.
Yes you run nmap in terminal. Download it from https://nmap.org/book/inst-macosx.html
For a ping sweep you should use nmap -sP 192.168.1.0/24
I use the app LanScan for that.
If it's your network, why not log into the router and see the DHCP table?
The tools mentioned above will work too. Can also try pinging the broadcast address to see if anything else replies. Simple, but not foolproof. In a command window: ping 192.168.1.255... or whatever network/subnet combo you use.
