Why do folks insist on using the word "propagate" to talk about DNS?
DNS is _passive_ not _active_. DNS doesn't "propagate" anything. In
DNS, caches time out and when they do, the updated information is
retreived. But nobody else's DNS server contacts mine to propagate
(broadcast, circulate, transmit) anything. Even my master DNS server
doesn't broadcast changes to the slaves, it only signals the slaves
that something has changed. The slaves then request the information
out of cycle, but the master doesn't just broadcast it.
