IP address questions
Noticed something strange today on our network. If I ping and IP address of 192.168.200.50, I get a destination unreachable message. If I ping address 192.168.200.050, it pings without a problem. See Screen Shot below:

Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
Another thing that is odd is that any IP address with the number 8 or 9 in the address gives a message to please check name and try again. I have tried all combinations of numbers like 8, 18, 9, 19, 88, 99, etc...
See some examples below:
C:\>ping 192.168.200.080
Ping request could not find host 192.168.200.080. Please check the name and try
again.
C:\>ping 192.168.200.018
Ping request could not find host 192.168.200.018. Please check the name and try
again.
C:\>ping 192.168.200.019
Ping request could not find host 192.168.200.019. Please check the name and try

Good Catch JMoody10! I was on 200.40. Any idea why the IP address that have an 8 or 9 won't ping?
Do those machines actually exist?
