(This issue is on a 64-bit Windows 7 Professional)
This is similar to this other question, but in my case I was not preceding any of the IP-address numbers with a zero (so the answer from that question is not applicable).
In this case I pinged the IP-address 192.168.0.18 in an attempt to locate my network printer.
For some reason though the ping command response stated that it was from 192.168.0.8.
It looked like as shown below, or in this screenshot
C:\Windows\system32>ping 192.168.0.18 Pinging 192.168.0.18 with 32 bytes of data: Reply from 192.168.0.8: Destination host unreachable. Request timed out. Reply from 192.168.0.8: Destination host unreachable. Reply from 192.168.0.8: Destination host unreachable. Ping statistics for 192.168.0.18: Packets: Sent = 4, Received = 3, Lost = 1 (25% loss),
What could cause the response to be returned from a different IP-address?
