No, it's the same as I wrote regarding the dig results. That just means that nobody has an answer for that IP being associated with a domain name. I can plug a box into my network, give it the IP 192.168.1.6, but not bother to put any entries for it on the DNS server nor any hosts file. It'll still be useable on the network, but no other machine will be able to dig, host, or nslookup, it. And it won't be able to do some of those checks on itself. Being able to ping it would depend on its configuration. You'd want to try other means to determine if there is something using that address on the network. e.g. Play with the arp command. Did you try the other test I mentioned? Trying to get it to accept using that IP while it's not connected to your LAN? Of course there's a chance that it mightn't let you set an IP while there's no network cabled to it, you could work around that by connecting to just one other thing, something you're certain isn't the cause of the 192.168.1.6 issue. -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.)
