One of NTP client conf file look like this and in which I found only one line is enabled (multicastclient). I'm not clear about this. What I understood (assumed) is that, using this multicast address (22.214.171.124) the NTP client will query a bunch of internet NTP servers present in this network and try to get the time information. If it works in this way, will it not hang the internet as there could be billions of NTP clients querying at regular intervals of time. Please claify me.
> cat /etc/inet/ntp.client
# ident "@(#)ntp.client 1.3 00/07/17 SMI"
# An example file that could be copied over to /etc/inet/ntp.conf; it
# provides a configuration for a host that passively waits for a server
# to provide NTP packets on the ntp multicast net.
