# LAN Scanner **LAN Scanner** is a free utility that scans your local network by sending ARP packets and waits response to identify the devices that offer a service on a certain TCP-IP port. **LAN Scanner** can even detect devices behind a firewall, but it only allows to reach local devices (the ARP packets do not go beyond your router). After a scan, you can double-click the list to dump it into Notepad. Or click a column header to sort it. **LAN Scanner** is particularly fast: it is based on threads, and can scan a range of 256 addresses (e.g. *192.168.0.** ) in less than 1s. **LAN Scanner** is written by Nicolas Mougin (mougino@free.fr).
