Link-local Multicast Name Resolution (LLMNR)

The Link-local Multicast Name Resolution (LLMNR) is a protocol for name resolution of IPv4 and IPv6 addresses in local networks. The protocol is also used to identify neighbouring computers. This protocol is primarily found in Microsoft operating systems. LLMNR is a kind of extension for the NetBOIS protocol. The NetBOIS protocol is exclusively designed by IPv4 addresses. NetBOIS was also developed especially for the manufacturer Microsoft. The addition of LLMNR was also necessary because NetBOIS distributed system information unencrypted over the network. LLMNR increases data security accordingly. Both protocols therefore work parallel in the system.
