get multi local ips

ruby

net.adapters returns correct ip for internet connection,
net.ip returns another temp ip.

there is only one adapter, but it has two ips.

Hi Ruby,

The function net.adapters() returns at each iteration the name of a physical network adapter and the associated first IP.
net.ip returns the local IP that your computer use on your local network.

If you have one network adapter, net.ip should get one of the IP associated with it (but net.adapters() will return only the first).

I guess your computer use the second IP address associated with your network adapter.

ruby

well, if using python, from this page,

use the first answer, I got the first IP,

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(("8.8.8.8", 80))
print(s.getsockname()[0])
s.close()

use the second answer, I got the second IP,

socket.gethostbyname(socket.gethostname())

it is not uncommon for an adapter to have multiple IPs.
maybe return all IPs , on return only the "primary" IP (the one with a default route).

I have reworked the net.adapters() function to achieve that. It will be available in next LuaRT release.
The function will now return at each iteration the adapter name and a table containing a list of all its IP addresses.

Thank you for your feedback 😀
