Labs Americas Neighbor Discovery Protocol The Neighbor Discovery Protocol (NDP) is a protocol in the Internet protocol suite used with Internet Protocol Version 6 (IPv6). It operates in the Link Layer of the Internet model (RFC 1122) and is responsible for address autoconfiguration of nodes, discovery of other nodes on the link, determining the link layer addresses of other nodes, duplicate address detection, finding available routers and Domain Name System (DNS) servers, address prefix discovery, and maintaining reachability information about the paths to other active neighbor nodes (RFC 4861).[1] The protocol defines five different ICMPv6 packet types to perform functions for IPv6 similar to the Address Resolution Protocol (ARP) and Internet Control Message Protocol (ICMP) Router Discovery and Router Redirect protocols for IPv4. However, it provides many improvements over its IPv4 counterparts (RFC 4861, section 3.1). Technical details[edit] Router Solicitation (Type 133) Router Advertisement (Type 134) Redirect (Type 137)

digitalmedia.oreilly.com -- Welcome to the O'Reilly Digital Media Center Have you ever wanted to create an authentic looking Andy Warhol silkscreen? One of the most influential artists of the 20th century, Warhol was known for his avant-garde paintings and screenprintings. Remember Warhol’s garishly colored celebrity images of Marilyn Monroe, Elizabeth Taylor, or Mao Zedong? In the studio he called The Factory, Warhol took an assembly-line approach to his high-contrast, silkscreens and produced art as a mass consumable, like a t-shirt or a pack of gum. It’s not surprising that his art is still popular today, and there are lots of one-click Warhol solutions. But if you want the real thing, join Deke McClelland in the final episode of this dekePod series, as he dissects Warhol’s process, and shows you how to use Photoshop to render your favorite portrait in bona-fide Warhol magnificence.
