Lie,

Wow. Strangely, that script returned 192.168.1.106. However, in Snow
Leopard's airport settings, if I click on 'advanced' and then
'proxies', the default proxy for 'http' is 127.0.0.1:4444 (and in
these settings, the 'use proxy for http' is checked).

I just tried checking the unix files you mentioned. In etc/hosts, the
following info is displayed:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##


127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost
fe80::1%lo0	localhost

Also found a file called ntp-restrict.conf, containing:

# Access restrictions documented in ntp.conf(5) and
# http://support.ntp.org/bin/view/Support/AccessRestrictions
# Limit network machines to time queries only

restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery

# localhost is unrestricted
restrict 127.0.0.1
restrict -6 ::1

includefile /private/etc/ntp.conf

Not sure if these are what I'm looking for -- I'm new to unix so I may
need a bit more hand-holding here.

I appreciate your time and effort.
