Appendix C – Tools for Your
RF550VPN

PING

Ping is an acronym for 

P

acket 

I

nter

n

et 

G

roper. The PING utility is used as a diagnostic tool to

determine if a communication path exists between two devices on the network. The utility sends a
packet to the specified address and then waits for a reply. PING is used primarily to troubleshoot
Internet connections, but it can be used to test the connection between any devices using the TCP/IP
protocol.
If you PING an IP address, the PING utility will send four packets and stop.
If you add a -t to the end of the command, the PING utility will send packets continuously.

WINIPCFG and IPCONFIG

These tools find a computer’s IP configuration, MAC address, and default gateway.

WINIPCFG (for Windows 95/98)

1.

Select 

Start

 | 

Run

 and type 

WINIPCFG

.

2.

The IP address, default gateway (the RF550VPN IP address), and the MAC (adapter
address) display.

IPCONFIG (for Window NT/2000)

1.

From a DOS Prompt, type 

IPCONFIG

 and press 

Enter

.

2.

The IP address, default gateway (the RF550VPN address), and the MAC (adapter address)
display.

TRACERT

TRACERT is an extensive PING utility that allows you to trace the route of an IP address. The utility
reports the number of router hops, the time for each hop, and any failed attempts to cross a hop. The
information that is provided by this utility assists you to locate the specific site of a failed PING. You
can run TRACERT at the DOS prompt (e.g., c:\tracert www.yahoo.com). The utility will provide
information about the route and number of hops required to reach the destination IP address
associated with the network address or URL.
