Forget "Alien" for now. And 127.0.0.1 is the loopback device, and has nothing to do with anything here.
Focus!
Open a Teminal.app on your Mac and show the output of ifconfig -a, as well as trying the ping and ssh commands and questions from my previous post.

lo
LO(4) BSD Kernel Interfaces Manual LO(4)
NAME
lo -- software loopback network interface
SYNOPSIS
pseudo-device
loop
DESCRIPTION
The loop interface is a software loopback mechanism which may be used for performance analysis, software testing, and/or local communication.
As with other network interfaces, the loopback interface must have network addresses assigned for each address family with which it is to be
used. These addresses may be set or changed with the SIOCSIFADDR ioctl(2). The loopback interface should be the last interface configured,
as protocols may use the order of configuration as an indication of priority. The loopback should never be configured first unless no hard-
ware interfaces exist.
DIAGNOSTICS
lo%d: can't handle af%d. The interface was handed a message with addresses formatted in an unsuitable address family; the packet was
dropped.
SEE ALSO
intro(4), inet(4), ns(4)
HISTORY
The lo device appeared in 4.2BSD.
BUGS
Previous versions of the system enabled the loopback interface automatically, using a nonstandard Internet address (127.1). Use of that
address is now discouraged; a reserved host address for the local network should be used instead.
