Testing queries to OpenDNS from NH reveals no problems. Oddly, note in the article that the IPs returned in place of the NXDOMAIN belong to Earthlink. I have not tried this with a malformed DNS query yet as the author describes.

An anonymous reader writes
"An interesting (and profane) writeup of one frustrated user's
discovery that Comcast is actually intercepting DNS requests bound
for non-Comcast DNS servers and redirecting them to their own
servers. I had obviously heard of the DNS hijacking for nonexistent
domains, but I had no idea they'd actually prevent people from
directly contacting their own DNS servers."
If true, this is a pretty serious escalation in the Net Neutrality
wars. Someone using Comcast, please replicate the simple experiment spelled
out in the article and confirm or deny the truth of it. Also, it would be
useful if someone using Comcast ran the ICSI Netalyzr and posted the
resulting permalink in the comments.
