VM1 cannot ping VM2 because IP resolved in with incorrect IP

Hi,

I have two VMs (VirtualBox 2.14) running simultaneously on a host Ubuntu 8.10 x32. Network setting use bridge. The 3 machines (host, VM1, VM2) got IP dynamically from home router.

The two VMs are identical, the guest OS is Windows 2008. All 3 machines work OK individually (can connect to Internet). They can ping each other only if the IP is specified (example: ping 192.168.1.123)

What is strange is that if I ping by computer name, then the OS only see a strange IP of 208.67.217.132 The ping failed because this is not within the subnet 192.168.1.x I am using. The same "IP resolution error" occurred regardless how Lookup or ping is done (from host to VM, VM to host or VM1 to VM2).

What is the reason the OS resolve the computer name with 208.x.x.x instead of 192.168.1.x ?

For now, I fixed it by using a poorman's version by adding an entry in the hosts file. However, I would like to know where the 208.x.x.x came from.

Thanks in advance for any help.

Someone in the Ubuntu forum has help to find the reason. When the OS fails to resolve the name the request is forwarded to a DNS server which is 208.67.217.132 (OpenDNS, set in the router).

But still, where is the reason the two VMs cannot see each other by computer name?

EDIT: Got answer from friends and various Internet searches.

The two VMs (guest = WIn2008) doesn't have WINS server or Netbios over IP enabled. The router I use doesn't resolved Name to IP. The solution is to use static IP and edit the hosts file in each computer.
