object encapsulating what is most likely the machine's
LAN IP address.
This method is intended for use as a replacement of JDK method
InetAddress.getLocalHost, because that method is ambiguous on Linux systems.
Linux systems enumerate the loopback network interface the same way as regular LAN network
interfaces, but the JDK
InetAddress.getLocalHost method does not specify the
algorithm used to select the address returned under such circumstances, and will often return
the loopback address, which is not valid for network communication. Details here.
This method will scan all IP addresses on all network interfaces on the host machine to
determine the IP address most likely to be the machine's LAN address. If the machine has
multiple IP addresses, this method will prefer a site-local IP address (e.g. 192.168.x.x or
10.10.x.x, usually IPv4) if the machine has one (and will return the first site-local address
if the machine has more than one), but if the machine does not hold a site-local address,
this method will return simply the first non-loopback address found (IPv4 or IPv6).
If this method cannot find a non-loopback address using this selection algorithm, it will
fall back to calling and returning the result of JDK method
