Netflix Streaming
Manystream from netflix come from:
netflix-908.vo.llnwd.net netflix-480.vo.llnwd.net netflix-606.vo.llnwd.net
Potential block not recommended:
netflix-*.vo.llnwd.net netflix-[0-9][0-9][0-9].vo.llnwd.net lcdn.nflximg.com
Older advice was to block movielicense.netflix.com - however, this domain no longer resolves. nflximg.com.edgesuite.net does not resolve.
