Question : Ping Returns Wrong IP Address

I have three computers connected on a home network using a Belkin F5D7230-4 wireless router.  The network is set up for DHCP.  There are two desktop computers and one laptop computer.  One desktop is running Windows XP Home the other is running Windows XP Pro.  The laptop is running Windows Vista.  When I view the computers in the workgroup, I can see all three on each computer.  The problem is that when I ping the other two computers in the workgroup by name from the third computer I get the same IP address as a response (24.28.193.9) from each ping request.  I should get two different addresses returned.  The addresses should be in the range 192.168.2.2 - 192.168.2.99.  When I ping any of the individual compters by name from itself I get the correct IP address.  When I ping the individual IP addresses (192.168.x.x) I get the correct IP address back as a response.  It appears to be a DNS problem that I do not know how to solve.  There are no entries in the hosts file on any of the computers with an address of 24.28.193.9.  I am using RoadRunner as an ISP.  I thought I remember reading somewhere that 24.28.193.9 was one of their IP addresses.

Answer : Ping Returns Wrong IP Address

Well.... erm... then, this behaviour is normal, because if the names of your computers are not registered in the DNS of your ISP then you get a wrong info.
Any time when you ping a name, the name resolution will try to use local cache, if not then it will search for a WINS or DNS server to resolve the name.
I assume that the ISP is configured to answer with its IP when you try to resolve such names.
I think you should configure hosts file on each computer in oreder to get a good name resolution or to set up a DNS server(free version).
