The alias is within the same subnet as the primary address.
(ifconfig tu0 alias 16.190.64.112)
Trying to run ntpsetup on the client with the alias'ed NTP server name FAILS.

********************************************************************
^G NTP has already been installed on this host.
Would you like to change the current NTP configuration (y/n) [no default]? y
Default answers are shown in square brackets ([]). To use a default
answer, press RETURN.
Authentication mode
-------------------
Authentication mode causes the server to synchronize with peers only
if the peer has been correctly authenticated using a trusted key and
key identifier.
In choosing to enable authentication, you must already know the key
number and the key identifier in order to correctly configure each
host name and the /etc/ntp.keys file.
If you do not know this information, enter 'n' in response to the next
question. See the Network Administration manual and ntp.conf(4) for
information on authentication.
Would you like to enable authentication (y/n) [n]?
NTP Server/Peer Selection
-------------------------
During the selection of servers and peers, you will be asked
for a hostname, and for the mode, server or peer, to be
associated to each hostname.
Press RETURN to terminate the list.
Hostname of NTP server/peer [no default]: cochva
Mode for cochva (server or peer) (s/p) [s]?
Looking up host cochva ... found.
Is cochva running ntpd (V1) or xntpd (V2 or V3) (V1/V2/V3) [V3]?
Hostname of NTP server/peer [no default]:
The list of NTP servers is:
server cochva version 3
Enter "r" to REDO the servers list, "e" to EXIT the ntpsetup
procedure, or "c" to CONTINUE [no default]: c
Created ntp.conf
IMPORTANT NOTE
--------------
If any of the NTP servers you specified are not in
the same IP subnet as your system, you must run either
routed or gated in order to access them. Please
see the networking documentation to set up one of
these services.
[ Press RETURN to continue ] :
Xntpd (the NTP daemon) Options
------------------------------
NOTE: The default answers are RECOMMENDED.
Correct large time differences, -g
----------------------------------
If your system time differs from the network time by more
than 1000 seconds while xntpd is running, the daemon will
suspect that something is very wrong with your system or
your servers. It will then log a message to the syslog and
exit, to allow the system manager to resolve the problem.
The -g option allows xntpd to correct large time differences
without logging a message or exiting. It should be used by
systems which are not monitored very closely by a system
manager (such as workstations).
Would you like to use the -g option (y/n) [y]?
Prevent time getting set backwards, -x
-------------------------------------------
The -x option prevents xntpd from correcting time when the offset
is negative. This can happen for example if the server(s) have
fallen behind for some reason.
Would you like to use the -x option (y/n) [n]?
