So shouldn't the 10.1.101.52 address have been reported?
Nope. In out-of-the-box simple network setups (i.e. home network
in the form PC/laptop -> router -> internet) the address
resolution won't go further than your hosts file, which in turn
will always give you back the loopback address (more
specifically, the address that is specified for the hostname in
aforementioned file).
That's why both I and Dicebot mentioned there isn't any real way
to query your local addresses without any live connection: only
when a socket has a connection within a particular network can
you tell your own IP address in that network. The address itself
would depend on the network setup, your local routing
configuration, etc. Your machine can have several network
adaptors (ethernet boards, Wi-Fi, etc.), each configured with
(numerous) routing setups, plus the routers they're connected to
have their own routing setups... This can go on and on.
