New description:

 Using, i.e. ::1 leads to:

 {{{
 **** v1    0.1 CLI RX| IP constant '"::1"' could not be resolved to an IP
 address:\n
 **** v1    0.1 CLI RX| \tServname not supported for ai_socktype\n
 **** v1    0.1 CLI RX| (Sorry if that error message is gibberish.)\n
 }}}

 Test attached. Works fine in 4.0.

 This broke when Resolve_Sockaddr() was changed to use VSS_resolver().

 The workaround is to use [].
