If I'm inferring correctly from the wiki page on Norwegian internet, the DNS blacklist is not made public as they mention it was posted to wikileaks back in 2009. At the time I believe this was exclusively a CP blacklist [1]
The mandate to block torrent sites came about as a result of a court order following a lawsuit brought forth by Hollywood studios against Norwegian ISPs [2]. I tried to find the specific text on lovdata, but came up empty as they don't have a comprehensive list of local court decisions. [3]
