This was totally an isolated incident, but I performed this command:

ping 192.168.1.134

and got this result [image]:

Pinging 192.168.1.134 with 32 bytes of data:
Reply from 192.168.1.133: Destination host unreachable.
Reply from 192.168.1.134: bytes=32 time=75ms TTL=128
Reply from 192.168.1.134: bytes=32 time=83ms TTL=128
Reply from 192.168.1.134: bytes=32 time=96ms TTL=128

note the .133 in the first 'unreachable' reply. I guess I don't understand how this is possible - even given a totally crazy coincidence.
