Comcast has recently deployed DNSSEC across its entire network. This will protect Internet users by checking websites for a special DNS signature and identifying them. It is a new technology that protects users from phishing websites. However, Comcast had to pay a price for this network upgrade. After this upgrade, the Comcast network is incompatible with DNS redirect tools. Comcast has been one of the primary supporters of SOPA and this upgrade eliminates the possibility of DNS level blocking, something that SOPA was totally relying on for removing supposedly rouge websites.

If you were wondering what DNSSEC is,

The Domain Name System Security Extensions (DNSSEC) is a suite of Internet Engineering Task Force (IETF) specifications for securing certain kinds of information provided by the Domain Name System (DNS) as used on Internet Protocol (IP) networks. It is a set of extensions to DNS, which provide to DNS clients (resolvers) origin authentication of DNS data, authenticated denial of existence, and data integrity, but not availability or confidentiality.

Comcast DNS Engineering Manager, Chris Griffith, says

DNS redirect services… are technically incompatible with DNSSEC and / or create conditions that can be indistinguishable from malicious modifications of DNS traffic.

Comcast is torn apart between its lobbyists and technical force. As evident from this, SOPA is bad for business and after all, business is what every company is out here to do! This move by Comcast also sends a strong message that when it comes to SOPA vs. business; companies will obviously go for business. With SOPA getting weaker each day, let us all hope that this SOPA soap opera ends soon.
