No Mikrotik routers between your PC and the Internet? 

Task Manager or Performance Manager will also tell you what IP or maybe FQDN 
the content is coming from as well.

used the wrong term 
Ignore the term 
Take cache out of thyne mouth 


now, being a windows dick, I dont have torch 


I want to simply be able to verify that appropriate CDNs are being utilized 


namebench is still running, I dont know what its output is going to be 


This cant be a new thing, I see threads occasionally about content being 
problematic in that users are getting less than desirable CDNs, it always seems 
to boil down to DNS, 


I just want a tool that will tell me where the content is coming from. (in a 
perfect world, it would display on a map with a quality indicator to that CDN, 
I dont have any expectation that that component of the tool would exist)

Not generic. You have to use the one they provide. And they will not give to

I was not aware you could cache Netflix streams with a generic caching server. 
Not only due to DRM, but also Netflix app switches streams dynamically to match 
video quality to connection speed. Plus first the customer authenticates to 
Netflix server, chooses what content to watch, etc.

Say a new movie is on Netflix. Or latest season of cards. Everyone is going to 
want to watch it. So 1000 simultaneous backbone streams to Netflix vs 1000 
simultaneous streams to the caching server in your NOC. I choose the latter.

I don’t understand how the caching server is going to help with CDNs. Actually, 
with so much Internet content now being either dynamic HTML or streaming, I 
wouldn’t think caching would be worth it, unless you are talking about 
something like a Netflix OpenConnect appliance. Maybe you can cache software 
updates, I’m not sure about that.

Geographically close CDNs. I want to make sure we are getting content from 
Illinoisish rather than california for netflix, since all that matters is 
netflix

For performance, look at queryperf which I think is provided by ISC/bind. 

I'm not sure what you mean by "we are getting good CDNs and the like," though.

Im bringing live our first caching server today. Is there a good tool for

Im not all that concerned about speed since we are so small there wont be a 
huge amount of benefit I would think. Im primarily wanting to make sure we are 
getting good CDNs and the like
