"Reality" for the last ten years has been that no one did either PPLB or TCP DNS. That reality is changing. It'll probably start to change faster, sooner. Then, users will start to notice the problems.
People have been using TCP applications on anycast for at least a decade, as I mentioned before. Since DNS responses tend to be very short lived TCP session, it seems to me that if it works for other applications (e.g. HTTP), it should work for DNS.
Its funny how I give you TWO conditions, and you ignore one of them. I'll try to use little tiny baby words:
TCP Anycast does NOT work with PPLB (Per - packet - load - balancing) Say it slowly several times.
oh well, I tried to stay quiet :) Probably the PPLB problem isn't quite as simple as: "you have pplb you can't do anycast". I'd imagine that you have to have some substantial difference in the paths that the PPLB follows, yes? like links to differing ISP's or perhaps extremely diverse links inside the same ISP. Correct?
