Given that we already have `network-interface-list' and
`network-interface-info' I think this should be named `network-address-info'.

Your patch works on Windows 10 (64bit mingw64 MSYS2):

ELISP> (get-address-info "www.slashdot.org" 'ipv4)
([216 105 38 15 0])

ELISP> (get-address-info "google.com")
([216 58 213 110 0])
