# Ping (Internet Control Message Protocol Ping)

The DVL responds to ICMP Ping requests on the Ethernet interface only. If you use DCHP to obtain an IP address the DVL attempts to register its name as “dvl”. The DHCP server is not obligated to accept the name request, and many do not. If it does, you can ping a DVL by name, e.g., “ping dvl” from your host computer command line. Otherwise, you must give the ping address in IP dot notation, e.g.,

C:\Users\Billybob> ping 192.168.2.8
