 In IPv6 mode, Windows Vista can use the Link Local Multicast Name Resolution (LLMNR) protocol to resolve names of local hosts on a network which does not have a DNS server running.The new TCP/IP stack uses a new method to store configuration settings that enables more dynamic control and does not require a computer restart after settings are changed.The new stack is also based on a strong host model and features an infrastructure to enable more modular components that can be dynamically inserted and removed.
