Can you torch the traffic to the 2 different IPs and see if anything is different? Same number of TCP connections and coming from the same place? Is there something different in your rDNS that could be confusing Netflix to think they should send from a server halfway around the world or something?
It is also rare for Netflix to rebuffer these days, since they are pretty good about switching stream rates on the fly. Well, depending on the streaming device. I hate these “smart” TVs, who knows if the app has been updated. Also home WiFi can be an issue. I’ve had customers complain about Netflix rebuffering on their WiFi connected smart TV or even not even being able to load the app, yet I plug my laptop into their router and stream Netflix flawlessly. Then they start with “it doesn’t happen all the time”, in other words it’s only working because you’re here.

Join an IX. Wait, so just their IP is bad? Another IP is good?

Naturally they claim Netflix constantly buffers and accuse me of throttling Netflix – we’re doing no such thing. For giggles I kicked their SM for a moment and put their pppoe account in a laptop at the NOC, set the throttle exorbitantly high (100mbps) and let it rip. 2mbps to fast.com, 99mbps everywhere else. Testing an adjacent IP in the same subnet will do 99mbps at both fast.com and speedtest.net. I would be on the phone with my upstream asking questions if other IPs in the same subnet were experiencing the same results. This whole thing feels like Netflix is targeting individual IPs with a throttle hammer. Any ideas here? Chris Wright Network Administrator
