The test ping is a 10 packet sequence, paced moderately slow, and should not cause any
problems to the host you have requested.
If this proves not to be the case, please leave a comment to the sysop.
You may enter a dotted-quad like 38.103.63.18 or a simple host name like www.example.com.
Normally it is best to test the numeric address first, and if that is successful, test the host name.
If this utility is too simplistic for your needs, try advanced ping.
