Continual DNS queries to akamaiedge.net
I have a relatively fresh install of Mountain Lion on a new MBP Retina.
I recently installed iStat Menus to keep an eye on resource usage and noticed that there is around 70KB of network activity every 15 minutes or so. It's pretty continual and lasts for around 5 minutes. This is with no user/foreground applications running.
I was curious about what the traffic was, so I installed Wireshark to take a look at the traffic. I left a capture running for a while until I grabbed the activity in question.
Looking at the capture decode, it looks like the traffic is made up entirely of DNS queries to e3191.c.akamaiedge.net over TCP. The queries come from the Mac, and valid, non-error responses come back from my router. Then the same query is made again. Over and over.
It's not a big problem, but it does suggest that there's a bug with some piece of code. I still don't know what's triggering the requests: something in OS X itself or some third-party code.
Has anyone seen behavior like this or have any idea what it might be about? How about a way to narrow down the offending software?
Curiosly,
