Obvious and prior art
Agile network protocol for secure communications using secure domain names
US 7921211 B2
As a former protocol engineer for Tandberg AS (now Cisco) who implemented time synchronization and encryption as well as NAT/firewall traversal code, I would dispute this patent as :
a) unoriginal... the described invention is not an invention rather than a bundle of other peoples inventions in an obvious manor. The description on the invention even spells that out.
b) impractical... even in a QoS enabled environment with cut-through low-latency switches, the application of this combination is ... as Sarah Palin would say non-sensical. I highly doubt Apple implemented this "invention" as suggested.
c) obvious ... dns proxying has been a hiding technique we all have used for decades before this patent.
d) unoriginal again... obfuscation by "shaking the box" has been around since the 70's... even in film references.

I haven't read it all the way through since it's so silly (almost a duplicate of the other) that it was granted. I feel that they chose their specific wording to make it so the patent reviewer wouldn't understand it well enough to say no to it. I probably could find 1000 holes in this one without much effort from the skimming I've done so far.
These patents feel like they were written because the author thought they were so smart and no one else would think of these things. In reality, they appear pretty simple and I'm almost 100% convinced that I could easily dispute most of the claims made. Of course, I would be shocked if there aren't earlier patents which would be applicable as prior art but would open things up for another case. People patent this stuff all the time. They pick some REALLY obvious stuff, write it down somewhat cryptically, pay a fee and then sue.
I don't care much for Apple, but I dislike patent trolls more.
