How can i configure a load balanced ntp servers

Question

i want to use ntp.nict.jp server for ntp in my linux machine . When i am configuring this server am getting the following ntp status :

[root@machine~]# ntpq -p
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
 ntp-a2.nict.go. .INIT.          16 u    -   64    0    0.000    0.000   0.000

What i could see is that the domain ntp.nict.jp is load balanced to different domains

ntp-b3.nict.go.jp(133.243.238.164)
ntp-a3.nict.go.jp(133.243.238.244)
ntp-b2.nict.go.jp(133.243.238.163)
ntp-a2.nict.go.jp(133.243.238.243)

and if i am configuring any of the domains in the above list , the ntp works fine .

i wish to configure the entire servers under ntp.nict.jp for ntp.

How can i do this ?

You can use the "pool" command in the ntp.conf file as follows.
