Can't Ping Localhost Over IPv4 Only IPv6
Apr 14, 2011
I have a QNAP NAS and several devices (mostly Windows 7 and iOS devices)The vast majority of my networking setup seems OK - however on one Windows 7 laptop I am having problems. The Laptop can 'see' remote shares, access the Internet and ping other devices on the network - however remote devices cannot ping the laptop. Whilst trying to ascertain what could be the cause I thought that I would ping 'localhost' on the laptop - after all, it should be able to see itself!

I'll try my best to explain all the issues clearly.from very above downto the third line are:IPv4 connection : not connected (Not OK, it wasn't like that)IPv6 connection : not connected (No public IPv6 connection in China, this is OK)Media State: connectedBut as you can see below, network is OK (Yeah, it seems that). The problem is, this ADSL connection is not showed in 'Avtive Networks'.Most online activities are OK, but somw applications like EA Origin are malfunctioned(I'm sure it is because of the problem in network connection)I've tried reset my winsock, LSP, netsh int ipv4,also reinstalled drivers. All above didn'you may wanna have a look at my Network and Share Center. Here it comes.Area 1 shows that there is no active networks except a 'unidentified network'(this refers to Local Area Conncetion. Since I don't neither have a router nor use LAN, that don't matter). When ADSL was OK, I got a active ADSL network there.

My wifi was working fine a few days ago but i think the windows update has messed up my wifi adapter or connection. I did do a system restore when this happened a few days ago but since the restore is more then 1month old it is no more.So far i have tried the following:restarting/rebooting router,updating/reinstalling drivers,and many other things but nothing seemed to work i dont understand why it is scanning for wifi but on the mapping it says adapter isnt connected.I have shown a few pics to help you:

I recently had a sound problem on the internet in google chrome ( no sound at all although the system sound worked fine). Installed shockewave and reinstall chrome on my pc and reboot my pc all remotely. At this stage my problem with chrome was not solved (although the sound in Explorer and firefox worked). After the remote reboot I could not reconnect to the internet. The local area connection status shows that ipv4 & 6 is not connected anymore.
I tried to turn on and off my network adapter, turn off my firewall and connect my pc directly to my cable modem( instead of being connected to my cisco 4200 v2 router) but nothing! I also tried to restart the DNS Client service and the DHCP client service: still nothing. The windows troubleshoot indicate a problem with the network adapter driver but I doubt it. I am running windows 7 ultimate.

I am using Windows 7 Pro and I can't access the Internet My IPv4 is working but I get this:
IPv4 : Internet
IPv6: No Internet Access
But when I open Browser I get white page but on vBulletin forums I get a 404 error on Every Forum site I go to. So I have a laptop, my brothers computer, xbox360, and my own pc all connected wired to the same router. Recently my PC is unable to get any internet at all from anything, even though it says:
ipv4 internet
ipv6 no internet access
It shows I am receiving and sending packets but not very often. All my other computers on my network except my one PC, I thought maybe it was my integrated network card on the computer but it seems I am not the only one who has had this problem.

I have a desktop that is connected to my Belkin router via wire. I have 3 laptops that are all connected to the router wirelessly. All computers have Windows 7 64bit and synched clocks. All are connected to a Home network. All 3 laptops detect that a Homegroup has been created on the wired desktop. I'm using the correct Homegroup password. All computers have discovery on. All computers have IPv4 and Ipv6 running. All services are running. Everything else I've read and tried regarding troubleshooting this issue haven't worked. All computers can see each other on the Network, but can't connect to the Homegroup.

I would like to know how you can redirect an external IP to localhost. Im trying to emulate the server for a simple program one of my friends coded in C++ (or something). It is basicly a login and register system, upon registering the program sends a HTTP request to the server (it requests a PHP file) with username & password parameters, if the username is not taken the server replies "1", if it is taken it replies "0".I made a PHP file on my server with the same name, though it would only return "0".So here is the deal, the program connects to a server that i dont have access to, nor do i have access to the program's source code and i can't change what IP the program connects to, so i will have to somehow forward the IP it connects to to my server's IP.

On a Win7Pro-32 system running in XP mode, I'm trying to use ODBC (v5.1.9) to connect to a MySQL db on localhost. Interestingly, when using a username with remote host privileges I am able to connect to a remote db - this tells me ODBC is installed and working properly. Yet when I try to connect to localhost with a user DSN using a login that works on the XP mode host I get a Connection failed errorSo there's clearly something about ODBC to localhost. Any solution available?[Why ODBC in XP Mode you might ask? I'm trying to develop an Excel macro in XL2003 for a client. This is my attempt to replicate their environment without creating a mess of conflicts in my own working environment.]

Windows 7 64 bitI went to the Microsoft website and reset the hosts file. (I just copied the text on the page that said it was for the Windows 7 hosts) Prior to the hosts reset, the only text in there was 120.0.0.1 localhost. Anyone know what this means? This happened one other time before, so it has to be something.

first my connection recently started cutting out at random times. Restarting sometimes helped, but disconnecting from the wireless network or rebooting the network adapter didn't help(atheros ar9285). If i go under status in available wireless network it says i have not connected to ipv4 or ipv6. I get this message even when i can get on the net. If i press details nothing shows up. i have pinged Google and have 0% loss he is my ipconfig /all

recently the connection rarely fails, but i bridge my internet with my Xbox 360 so i don't have to pay for a wireless adapter, and when i do that sometimes the connection fails, or when watching netflix through Xbox it says i have lost signal or the signal strength has dropped, when nothing has changed on my laptops internet connection in terms of strength?

I have a brand new desktop running Win 7 64 bit and a laptop running Win 7 Ultimate.
The laptop uses IPv4 to connect, verified via ipconfig. The desktop uses IPv6. Each can see one another on the network, but cannot access one another. If I uncheck IPv4 on the laptop, I can then access the desktop PC, but cannot surf the internet. Once I click it back on, I lose access to the desktop.
I have tried connecting to both with and without homegroups enabled, but I think it's the IPv4 on the laptop that's causing the issue.
How can I get these two to play nice? The laptop hooked up wirelessly with an Aetheros AR5007EG adapter via Realtek PCIe FE Ramily controller. Can I force the laptop to use IPv6 somehow?

We set up three new terminals this week at the office; they're all running Win 7 Pro 32-bit. I set them all up simultaneously (literally sat at a desk and entered the same keystrokes at each of them), so I don't see any obvious reason that one is behaving differently from the other two. The essential problem is that the terminal doesn't see the Internet.
Here are all the particulars that I think might be interesting, listed in no particular order:
- The terminal ran fine for several hours. Email access, Internet access, from 9 a.m. to 2 p.m. At that point, the user called me to show me a dialog box. I used System Restore to go back in time to 9 a.m. in case the user had somehow managed to do anything (though she's not an admin).
- IPv6 is disabled.
- The workplace uses Static IPs. The IP address is entered correctly in the IPv4 properties (x.x.x.213), but at cmd / ipconfig, I get this result: "Autoconfiguration IPv4 address: 169.254.95.187"
- In Network and Sharing Center, the network (which is only known as Unidentified Network) is set to type Public. When I reset it to type Work and reboot, it resets to type Public.

i have Windows 7 ultimate 64bit and XP Pro 32bit, and here is my issue: i have a huge network and i have to set my IPs
IPv4:
IP Adress 10.100.150.200
Subnet M: 255.255.128.0
Gateway: 10.100.20.1
DNS: 10.100.0.3
This settings work on all XP OS but doesnt work with all Windows 7. It works for 5-10 min then it says no connection. After set IP it works then doesnt work. If i ping 10.100.20.1 -t it pings as much as i want until i stop and if i restart ping it doesnt work, while first ping i can access to internet after stopping the ping no internet also, That win 7s works with normal ip configurations like: ip:192.168.0.10 gateway: 192.168.0.1
Does windows 7 have problem with different gateway problem? or is it a bug?

Quote: The move to Internet Protocol version 6 (IPv6) could have a profound affect on the Internet, breaking it up into islands of connectivity and threatening cybersecurity in the process, according to Jeff Young, a senior analyst at the Burton Group.
As the IPv4 free address pool continues to dwindle, enterprises can expect to see IPv6-only hosts on the Internet within a three-year timeframe, Young said. In the report, "IPv4 Address Exhaustion: An Inconvenient Truth," Young addresses the incompatibility of IPv4 and IPv6 and some of the problems that need to be addressed during the changeover.

Looks like its time to upgrade from my older Linksys WRT54GX router to a new one. My question is which new routers support IPv6?? How can you tell?? Is there a comprehensive list of new routers supporting it? (If I am to upgrade, might as well get a nice one that supports it).
good/great (wireless) router that plays nice with Windows 7 x64? Something in the sub $200 range. Willing to spend more for a better product. (In doing some research I have seen poor reviews for virtually all routers, no matter the make/brand... so maybe I should be looking for the "LEAST WORST"..LOL)
Currently I have 4 hardwired computers and 4 wireless devices (1 computer, 3 "other"--ipod touch, wii, etc)

I have a set of PCs which if connected to a windows network will make all computers on that network default to ipv6 when resolving names. This happens even if IPv6 is unchecked, if the ipv4 binding is set above 6 in the advanced properties of the network card. If any of these PCs joins a network with a point of sale system (Aloha) that system develops problems since Aloha does not like IPv6. At all. All computers including the aloha terms are Windows 7, 32 or 64 bit. Reproduced this with different routers and network topologies.
For example, I take one of these particular PCs to my home network Prior to the terminal going onto the network
ping localhost --> 127.0.0.1
ping computername --> 192.x.x.x
After the PC has joined the network, just attached to the same router, not on the same workgroup, etc., now all computers on the network return
ping localhost --> ::1
ping computername --> 08fe:xxxx (IPv6 address)
ping computername -4 --> 192.x.x.x
ping localhost -4 --> 192.x.x.x
This behavior continues even without IPv6 enabled on any adapter on the network. When the PC is removed from the network, all other PCs continue with the new behavior. I have tried netsh winsock reset, net stop dnscache, netsh int ip reset.log hit, unchecking IPv6 in multiple places, ensuring binding order has IPv4 above IPv6 on all network adapters (none hidden) etc. It's like this PC infects other windows PCs with IPv6. I have not tried disabling IPv6 from the registry or by Policy in my lab but I believe I tried this on previous network with no effect.

i already follow this guide: How to disable certain Internet Protocol version 6 (IPv6) components in Windows Vista, Windows 7 and Windows Server 2008 to disable ipv6. and already try all combination from 0xffffffff until 0x11
0xffffffff will disable ipv6, but listening port still bind to ipv6.
for example, i still can ping ::1 even though that above registry editing should "disable the ipv6". and when i do netstat -an | find "LISTEN", some ports still bind to ipv6, for example:
TCP [::]:80 [::]:0 LISTENING
TCP [::]:135 [::]:0 LISTENING
TCP [::]:443 [::]:0 LISTENING
TCP [::]:445 [::]:0 LISTENING
and so on. anyone have solution to permanently disabling ipv6? the reason why i want to rid of ipv6 listening is because it cause conflicting to my router when want to do port forwarding. i don't have any problem to port forward to other machine installing windows xp/2003. tq.
