The Calcutta High Court has asked all Indian ISP's to restrict access to 104 web sites which provide pirated music online. Indian Music Industry(IMI), Sagarika Music, and Phonographic Performance Ltd had moved to court against 11 ISP. Internet Service providers were unable to represent themselves in the court, which led court to order all the ISP to ban all these sites.
Court ordered to completely ban access to these sites either by blocking the domain and IP address or using Deep Packet Inspection. Nearly 400 Internet Service Providers will have to take action against the sites in 36 hours. As of writing some sites were still working.
Last month hugely popular site songs.pk was banned but the site resurfaced using other domain name(we are not going to tell you which). Before that a court has also asked Internet Service Providers to Ban sites hosting recently released movies.

Deep Packet Inspection (DPI) (also called complete packet inspection and Information eXtraction - IX -) is a form of computer network packet filtering that examines the data part (and possibly also the header) of a packet as it passes an inspection point, searching for protocol non-compliance, viruses, spam,
intrusions or predefined criteria to decide if the packet can pass or
if it needs to be routed to a different destination, or for the purpose
of collecting statistical information. There are multiple headers for IP
packets; network equipment only needs to use the first of these (the IP header) for normal operation, but use of the second header (TCP, UDP etc.) is normally considered to be shallow packet inspection (usually called Stateful Packet Inspection) despite this definition.
