How to fix ipv6 without network access
The solution for ipv6 without network access is to check the network settings, update the network driver, and disable IPv6.
1. Check the network settings: When using IPv6, you need to make sure that the network settings are correct. Users can try to reboot the router or reset the network connection to make sure the IPv6 address is correctly assigned.
2. Update the network driver: If the network settings are correct, but IPv6 still can’t access the network, it may be because the network driver is outdated or corrupted. Users can try to update the network driver to ensure that the network adapter can correctly use the IPv6 protocol.
3. Disable IPv6: If neither of the above two methods solves the problem of no network access for IPv6, users can try to disable IPv6. Although IPv6 has a richer address space and a more efficient routing mechanism, disabling IPv6 can solve the problem of network access in some cases.
The Role of the IPv6 Network Protocol
IPv6 provides a larger address space because its address length is 128 bits, which is longer than IPv4’s 32 bits.IPv6’s address space is large enough to meet the future needs of the Internet, and also to avoid problems such as address conflicts and address shortages.
IPv6 has improved security by providing better encryption, authentication, and access control, etc. IPv6’s IPsec protocol encrypts and authenticates data to keep it secure.
IPv6 can support multicast and mobility, which means that information can be sent to multiple devices at the same time for more efficient communications. ipv6 also supports the mobile ipv6 protocol, which enables seamless mobility by allowing a device to remain connected to the network while on the move.
IPV6 no network access, can chat QQ, can play the game, is sometimes all web pages can not open, my is WIN7 system.
One of the problems with the network settings
This reason is more often found in the need to manually specify the IP, gateway, DNS server networking mode, and the use of proxy servers to access the Internet. Check your computer’s network settings carefully.
Two, DNS server problems
When IE can not browse the Web, you can first try to access the IP address, if you can access, then it should be a DNS problem, resulting in DNS problems may be connected to the network to obtain DNS error or DNS server itself, then you can manually specify the DNS service (address can be your local ISP to provide) DNS server address provided by your local ISP, or you can use other places where DNS server address can be used normally.) Do this in the properties of the network, (Control Panel – Network and Unplugged Connections – Local Connections – Right-click Properties – TCP/IP Protocol – Properties – Use the following DNS server address). Different ISPs have different DNS addresses. Sometimes it’s a problem with your router or network card that prevents you from connecting to your ISP’s DNS service, in which case you can turn your router off and on again, or reset your router.
There is also a possibility that there is a problem with the local DNS cache. In order to increase the speed of web access, the system will automatically store the web sites that have already been accessed with an IP address in the local DNS cache, so that once the web site is accessed again, it will no longer be accessed through a DNS server, but will be accessed directly from the local DNS cache by taking out the web site’s IP address. Therefore, if there is a problem with the local DNS cache, the website will be inaccessible. You can rebuild the local DNS cache by running ipconfig/flushdns in Run.
Three, IE browser itself
When the IE browser itself is faulty, it will naturally affect the browsing; or IE has been maliciously modified to destroy will also lead to the inability to browse the web. At this time you can try to use the “Huangshan IE repair experts” to repair (recommended to the safe mode repair), or re-IE (such as reinstallation of IE encountered can not be re-problems, you can refer to: attached to a solution to the inability to re-install the IE)
four, the network firewall problems
If the network firewall improperly set up, such as too high a security level, the firewall is not the best way to protect your computer. If the network firewall is not set properly, such as too high a security level, accidentally put IE into the blocked access list, the wrong firewall policy, etc., you can try to check the policy, reduce the firewall security level or directly turn off to try to return to normal.
Fifth, the network protocol and network card driver problems
IE can not browse, may be the network protocol (especially the TCP / IP protocol) or network card driver damage caused by, you can try to re-network card driver and network protocol.
Sixth, the problem of HOSTS file
HOSTS file is modified, can also lead to abnormal browsing, the solution is, of course, to clear the contents of the HOSTS file.
Seven, the problem of system files
When the system files related to IE is replaced or damaged, will affect the normal use of IE, then you can use the SFC command to repair, WIN98 system can be in the “Run” in the implementation of the SFC, and then perform a scan; WIN2000 / XP /2003 in the “Run” in the implementation of sfc/scannow try to repair.
When only IE can not browse the web, and
can be on, it is often due to winsock.dll, wsock32.dll or wsock.vxd (VXD only exists under the WIN9X system) and other files are damaged or missing caused by the Winsock is an important part of the composition of the TCP / IP protocol, generally to reinstall the TCP / IP protocol. reinstall the TCP/IP protocol. However, XP began to integrate TCP/IP protocol, so it can not be as simple as 98 uninstalled and reinstalled, you can use the netsh command to reset the TCP/IP protocol, so that it is restored to the initial installation of the operating system when the state. The specific operation is as follows:
Click “Start Run”, in the Run dialog box, type “CMD” command, pop-up command prompt window, and then type “… netshintipresetc:\resetlog.txt” command will enter, which “resetlog.txt” file is used to record the results of the command execution of the log file, the parameter option must be specified, where the log file specified in the complete path is “c”, “c”, “c”, “c”, “c”, “c”, “c”, “c”, “c”, “c”, “c” and “c”. The full path of the log file specified here is “c:\resetlog.txt”. The result of this command is the same as removing and reinstalling the TCP/IP protocol.
Tip: The netsh command is a command-line based scripting tool that you can use to configure and monitor your Windows system, and it also provides an interactive network shell program interface. The format of the netsh command can be found in the help file (type “netsh/?” at the prompt). ” in the prompt window).
The second solution is to repair the above files, WIN9X use SFC to re-extract the above files, WIN2000/XP/2003 use sfc/scannow command to repair the file, when sfc/scannow can not be repaired, you can try to publish online repair tool WinSockFix specifically for this problem, you can search for downloads on the Internet. The first step is to find a way to get to the bottom of the problem.
Eight, the real-time monitoring of antivirus software
This is not often seen, but sometimes it does have to do with real-time monitoring, because the real-time monitoring of the antivirus software are now added to the monitoring of Web page content. To give an example: KV2005 will be in the individual machine will lead to IE can not browse the web (many friends have encountered), its specific performance is as long as the opening of the web page monitor, a boot online about 20 minutes after the IE will not be able to browse the web page, at this time, if the web page monitor KV2005 off, everything is back to normal; after a thorough reinstallation of KV2005 can not be resolved. Although not every machine with KV2005 installed will have this problem, after all, the system of each machine is different, and the installed programs are not the same. But if there is IE can not browse the web, also pay attention to check the antivirus software.
Nine, infected with a virus caused by
This situation is often manifested in the opening of IE, in the IE interface in the lower left box prompts: is opening the Web page, but the old days did not respond. In the task manager to see the process, (into the method, put the mouse on the taskbar, press the right button – task manager – process) to see how the CPU occupancy rate, if it is 100%, you can be sure, is infected with viruses, this time you want to run the other programs are simply suffering. This is to find out which process is greedily occupying the CPU resources. Find, it is best to record the name, and then click on the end, if you can not end, it is necessary to start to the safe mode to delete the thing, but also into the registry, (method: start – run, enter regedit) in the registry dialog box, point edit – find, enter the program name, find, point the mouse! Right click to delete, and then a few more searches, often can be completely deleted cleanly.
There are a lot of viruses that antivirus software can’t do anything about, and the only way to remove them is manually.
Local connection network display ipv6 no permission to access, some applications and websites can not be accessed,
You are sure to have ipv6, at present, the education network is there, the major carriers have not been on the home to support.
