Harry de Grote mentioned:

The hacker's choice R U There (or just "THCRUT") facilitates this nicely.
Give it an IP and subnet mask, and that sucker will spit out several
thousand parallel threads for ARP requests. Scan a B in nothing flat.
What's great is, not many systems detect ARP scans yet, so your IP-layer
scan detectors generally miss this.
