[Fed-Talk] OS X chatting with DNS server via port 5353

Why does OS X continually chat with your DNS server via port 5353?

I have verified that this is not DNS lookups, i.e. I lose no functionally when I block this traffic; however, depending on how this traffic is blocked my logs fill up with different types of messages.

I gather OS X is trying to advertise to the DNS server what services it offers. This is something that should be possible to turn off without creating megabytes of logs.
