What is the number between brackets next to the interface name in
In the following output i.e.
en0 (17): inet address 192.168.4.5
As requested I add more info.
I was using
ifconfig on Ventura but this called the Homebrew command instead the native one.
/sbin/ifconfig i got the output without the brackets.
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ... ..
