LLMNR (Link-Local Multicast Name Resolution) and NBNS (NetBIOS Name Service) are both protocols used in computer networking for name resolution
LLMNR is primarily designed for local networks and helps resolve the names of neighboring devices when traditional DNS (Domain Name System) is not available.
It uses multicast packets to send name resolution queries to all devices on the local subnet, allowing devices to resolve each other's names without relying on a central DNS server.
LLMNR is especially useful in environments where DNS infrastructure is limited or absent.
On the other hand, NBNS, also known as NetBIOS Name Service or WINS (Windows Internet Name Service), is an older protocol used primarily in Windows-based networks for NetBIOS name resolution.
NetBIOS names are short, alphanumeric identifiers used to identify devices on a network.
NBNS resolves NetBIOS names to IP addresses, allowing devices to communicate using these names.
However, NBNS is less commonly used today due to the prevalence of DNS and more modern name resolution technologies.
Summary:
- LLMNR is a local network protocol for name resolution using multicast packets, helpful when DNS isn't available
- NBNS/WINS resolves NetBIOS names to IP addresses in Windows networks, though it's less utilized today with the dominance of DNS.
