=46rom the 4.2.6 ntpd(1) man page on Mac OS X:
-I iface, --interface=3Diface
Listen on an interface name or address. This option may =
appear
an unlimited number of times.
Open the network address given, or all the addresses =
associated
with the given interface name. This option may appear =
multiple
times. This option also implies not opening other =
addresses,
except wildcard and localhost. This option is =
deprecated.
Please consider using the configuration file interface =
command,
which is more versatile.
And for ntp.conf:
> interface [listen | ignore | drop] [all | ipv4 | ipv6 | wildcard | =
name | address[/prefixlen]]
>=20
> This command controls which network addresses ntpd opens, and whether =
input is dropped without processing. The first parameter determines the =
action for addresses which match the second parameter. That parameter =
specifies a class of addresses, or a specific interface name, or an =
address. In the address case, prefixlen determines how many bits must =
match for this rule to apply. ignoreprevents opening matching addresses, =
drop causes ntpd to open the address and drop all received packets =
without examination. Multipleinterface commands can be used. The last =
rule which matches a particular address determines the action for it. =
interface commands are disabled if any -I, --interface, -L, or =
--novirtualips command-line options are used. If none of those options =
are used and nointerface actions are specified in the configuration =
file, all available network addresses are opened. The nic command is an =
alias forinterface.

So be mindful about that option if you every upgrade.
