Computer returning wrong dns address when pinged

pinging my laptop from my workstation using its windows name returns a dns of 66.115.130.138. I dont know what that address is for. If i ping any word from the workstation I get the same result. Even tried pinging the word crap, got a reply from 66.115.130.138.

Internet and network working fine except for a rendering program (vray) which uses other computers on the network to render images. Need this program to work.

It simply means that the DNS you are pointing to can't resolve the simple name your are pinging. If you ping a FQDN, then you will get the usual can't resolve message.

On the problem machine, run TCP/IP Reset and DNS Flush.

Open cmd.exe with Run as Administrator
Then netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer

See if that helps.

Tried John's suggestions. And yes the returned IP address is now 66.115.130.139. Still wrong.
This is just a simple win7 home network with a verizon router MI424WR and a TPLINK gigabit switch.

Please do an IPCONFIG /ALL from command prompt on both machines and post the output here. Are you on the same subnet on both machines? Are both machines on the same WORKGROUP?

Something seems strange.

Can you give us a screen shot of exactly what you enter and exactly what you get back.

This is in-addition to the ipconfig /all that John Hurst requested.

My guess is you are ping'ing a name that does not have a valid DNS entry and the DNS server you are configured to use is setup to return a specific fixed IP address to for any lookups that are not valid.

You are trying to ping an internal network from an outside network. That generally will not work without a VPN connection.

giltjr

Yep " lenovo.home" is not valid on the public Internet. The DNS server is doing what I said, it has no clue about "levono.home" so it returns a fixed IP address of 66.115.130.139.

If you want to ping by host name for non-public names, you need to either setup your own DNS server or setup entries in your hosts file as Seth Simmons suggested.

John, I dont know how that is happening. These computers are all on the same network, same workgroup. Is this a firewall issue? I am using Commodo on all.

John

If that is true. why does the machine have an external IP address for its active connection? Are you connecting by cellular card?

george chianese

ASKER

Tried Seth's suggestion. Ping now returns correct address.

I have no idea. Connecting through ethernet network card. No other connections on that machine, not even wireless. I did use the log me in program a while back, could that have changed anything?

John

Did you flush DNS?

Thanks, I'll look into that.

I looked at the ipv4 settings of the network card. It had a manual entry for the dns server. Changed it back to automatic. Seems to be working now without having to change the hosts file.
