In a presentation at the Google IPv6 Implementors Conference, Facebook's network engineers said it was "easy to make [the] site available on v6." Facebook said it deployed dual-stack IPv4 and IPv6 support on its routers, and that it made no changes to its hosts in order to support IPv6. Facebook also said it was supporting an emerging encapsulation mechanism known as Locator/Identifier Separation Protocol (LISP), which separates Internet addresses from endpoint identifiers to improve the scalability of IPv6 deployments. "Facebook was the first major Web site on LISP (v4 and v6)," Facebook engineers said during their presentation. Facebook said that using LISP allowed them to deploy IPv6 services quickly with no extra cost. Facebook's IPv6 services are available at www.v6.facebook.com, m.v6.facebook.com, www.lisp6.facebook.com and m.lisp6.facebook.com. According to a June 2010 report by Network World, Facebook said that it was offering "experimental, non-production" support for IPv6, the long-anticipated upgrade to the Internet's main communications protocol. The news about Facebook's IPv6 support was expected; Facebook told Network World in February 2010, that it planned to support native IPv6 user requests "by the midpoint of this year." On August 13, 2010 Facebook launched a new service called "'Facebook Live'", a live streaming video channel that is intended to keep Facebook users updated to what is happening on the social networking site. The service, powered by Livestream, will feature videos from Facebook staff members and celebrity interviews, but not designed for Facebook users to showcase their own videos. All the content shown on Facebook Live will have some tie-in with Facebook products, features, or how people are using the site. Facebook said this is not an opening to get them into the video distribution space. The first official guest was America Ferrera, the leading actress in the television series Ugly Betty. She discussed her new independent film The Dry Land, that was being promoted almost exclusively through social media channels. On April 25, 2011, Facebook announced a pilot program called Deals, which offers online coupons and discounts from local businesses. Facebook initially released Deals as a "test" in five cities: Atlanta, Austin, Dallas, San Diego and San Francisco with the hope of expanding. This new offering is a direct competitor to other social commerce sites such as LivingSocial and Groupon for online coupons and deals-of-the-day. Facebook users will be able to use Facebook Credits to purchase vouchers that can be redeemed for real goods and services. As on 30 August 2010, Facebook gifts were disabled and from then on, Facebook credits are being used for the Games alone. Facebook Credits are a virtual currency you can use to buy gifts, and virtual goods in many games and applications on the Facebook platform. As of July 2010, users of Facebook can purchase Facebook credits in Australian Dollars, British Pound, Canadian Dollars, Chilean Peso, Colombian Peso, Danish Krone, Euro, Hong Kong Dollar, Japanese Yen, Norwegian Krone, Swedish Krona, Swiss Franc, Turkish Lira, US Dollars, and Venezuelan Bolivar. Facebook credits can be used on many popular games such as Happy Aquarium, Happy Island, Zoo Paradise, Happy Pets, Hello City,It Girl FarmVille, and Mafia Wars. On April 5, 2008, Facebook pre-released Facebook Chat. As of April 23, 2008, Facebook Chat was released to the entire Facebook user base. Users may chat with their Facebook friends on a one-to-one basis, or a user may chat with multiple friends simultaneously through the groups feature. Instant messaging clients that currently support Facebook Chat include AOL Instant Messenger, eBuddy, Flock, Miranda IM, Trillian, Empathy, Digsby, Pidgin, Adium, Nimbuzz, FIM (Windows Mobile / Windows Phone 7), Palringo (Windows Mobile), Meebo, Tokbox as well as QIP Infium with a Firefox plugin. Windows Live Messenger 2011 (Wave 4) can connect to Facebook as well. Facebook Chat can also be run on the desktop using Gabtastik, a dedicated web chat browser. Facebook Chat can also be run on the iPhone or iPad using Facebook Chat for iPhone app. On May 13, 2008, a Facebook developer announced that they are working on XMPP support, allowing hundreds of instant messaging clients to interoperate with the service; this functionality became operational on February 10, 2010. Facebook is a social networking website, founded in 2004. This is a list of features that can be found on the Facebook website, as well as technology features on the website.
