Comcast -- Owner Of NBC Universal -- Admits That DNS Redirects Are Incompatible With DNSSEC

Comcast, which owns NBC Universal, is officially a SOPA/PIPA supporter. However, Comcast completed its DNSSEC deployment, making it "the first large ISP in the North America to have fully implemented" DNSSEC across the board. That's huge, and a clear vote of confidence for DNSSEC, obviously. They also urge others to use DNSSEC.

But what may be much more interesting is that, along with this announcement, Comcast has also mentioned that it is shutting down its Domain Helper service. Domain Helper was a somewhat controversial DNS-redirect system, so that when you mistyped something, it would suggest the proper page or alternatives. Many in the internet community complained that these types of redirects mess with the underlying DNS system (which they do). But, as the DNS experts have been saying all along (and NBC Universal has been trying to play down), DNSSEC is incompatible with such DNS redirects. So... that makes this next part a little awkward. Comcast is now admitting, indeed, that DNS redirects, such as Domain Helper, are incompatible with DNSSEC.
