The Link Local Multicast Name Resolution (LLMNR) is a protocol based on the. (DNS). protocol that allows computers to perform name resolution for addresses on the same local network without the. need for a centrally coordinating DNS server.he DNS process for LOCAL name resolution. The problem arises because all older computers running LLMNR listen on the IPv4 multicast address 224.0.0.252. and instruct their Ethernet network adapters to listen for Ethernet frames with a destination multicast address.
