For a given subnet, any host can broadcast an ARP request for another host on the same subnet.  All hosts on the network receive the broadcast and answers are unauthenticated.\n\n[RFC 5227](https://tools.ietf.org/html/rfc5227) expands upon the initial ARP specification by providing a new type of ARP frame, known as an ARP Probe.  An ARP Probe is meant to prevent IP address collisions.  When a host first wishes to use an IP address on a given network, RFC 5227 compliant operating systems must send an ARP Probe for the desired IP address.  After a timeout period, the host considers the IP address unused, and is free to claim it.\n\nNARP answers all ARP Probes, preventing any new host from claiming an IP.\n\n![NARP](narp.gif?raw=true)","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fraidancampbell%2Fnarp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fraidancampbell%2Fnarp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fraidancampbell%2Fnarp/lists"}
