mdns-scanner
TUI for scanning networks and mapping IPs to mDNS hostnames
TLDR
SYNOPSIS
mdns-scanner [options]
DESCRIPTION
mdns-scanner is a terminal UI application that scans the local network for active hosts and resolves their IP addresses to multicast DNS (mDNS) hostnames or DNS-SD service instances. It enumerates non-loopback network interfaces, performs ARP/ICMP-based host discovery, then issues mDNS queries on the 224.0.0.251 (IPv4) and ff02::fb (IPv6) link-local multicast groups on UDP port 5353.The TUI displays discovered hosts in a navigable list with their IP addresses and any resolved **\*.local** hostnames or service records, making it useful for finding printers, Chromecasts, Apple devices, HomeKit accessories, and other Bonjour/Avahi-aware hardware on a LAN.
INSTALL
CAVEATS
Only discovers devices that respond to mDNS queries. Devices without an mDNS responder (or with mDNS blocked by firewall rules) will not be resolved, though they may still appear by IP. Multicast traffic does not cross routed segments by default, so the tool only sees the directly-attached broadcast domain.
HISTORY
mdns-scanner was created by CramBL and is written in Rust. It is published on crates.io and distributed through cargo install mdns-scanner.
