Hi.
I'm not sure what OS you have on your main computer but if you know the
mac address of the pi here is another solution.
If you have access to a linux machine on the network use "arp-scan".
arp-scan --localnet ma:ca:dd:re:ss
Replace Macaddress with the actual mac of the pi

probably 5 years. Everybody lately has been playing nicely.
Next, most users do have access to this information especially on home
networks. If not then one could use something like an intermediate
router that you do have access to. They make small pocket sized
devices that can grab on to a WiFi signal and then redistribute it to
your devices. It has built in NAT and DHCP so you could easily grab
what you need from your interface on the small box.
On your Mac I’m not sure. I think this is a cool solution but haven’t
tried this myself. There is definitely in there a list of leases that
you should be able to query from dhcpd. This would be most likely
accomplished via logging in to the Mac with ssh and issuing the proper
command but I don’t know what server variant you're using to help with
specifics.
Typically this type of thing is best gotten from the router as far as
most consumers go. Most do not use a Mac or intermediate home brew
setup. Nothing wrong I’m just probably stating the obvious but giving
the lay of the land a little.

Just log in to your router that’s handing out IP addresses, look for

be as simple as reading a page or the output from a command

assume your router for example is your DHCP server and you’re not
running your own domain controller etc.
allocations, so we'd probably have to send a request to the Mac. Is
there a portable, network-based way to get this sort of information
from a router and/or the DHCP server?
Logging into the router, as you suggest, may not be an option for the
user. For example, they might be a student living in a dormitory or a
client in a coffee shop. Also, there's no guarantee that the router's
administrative interface is blind-accessible.
So far, this doesn't seem like a very general solution, but I'm
certainly willing to keep the discussion open...
