Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur. Additionally, system startup will be delayed for 5 seconds if IPv6 is disabled by incorrectly, setting the DisabledComponents registry setting to a value of 0xfffffff. The correct value should be 0xff. For more information, see the "What are Microsoft's recommendations about disabling IPv6?
The DisabledComponents registry value does not affect the state of the check box. Therefore, even if the DisabledComponents registry key is set to disable IPv6, the check box in the Networking tab for each interface can still be checked. This is expected behavior. Administrators must create an. By default, the 6to4 tunneling protocol is enabled in Windows Vista, Windows Server or later versions when an interface is assigned a public IPv4 address that is, an IPv4 address that is not in the ranges If this behavior is not desired, we recommend that you disable IPv6 tunnel interfaces on the affected hosts.
Note Replace the value with the corresponding value in the previous table. Windows use bitmasks to check the DisabledComponents values and determine whether a component should be disabled. For each bit, 0 means false and 1 means true. Why changing DNS server can be worthwhile When connecting to the internet via a router, you automatically obtain not only the IP address but also the DNS server settings. However, changing the standard DNS server may be necessary or advisable for the following three reasons : Speed : Another DNS server may offer a speed advantage in name resolution, resulting in faster loading times and a better ping in online games.
Tools like namebench help you to find the quickest DNS server for you. Availability : The DNS server may not be available, which stops name resolution in its tracks and prevents websites from loading.
This is usually due to a temporary problem that can be solved straight away by changing DNS servers, without having to wait for a solution from the provider. In this case, name resolution will not be performed and you will be denied access to these websites.
If you connect the device to the internet both via cable and Wi-Fi, it is recommended to change the DNS server for both connection types. Manually configuring the DNS server allows you to enter two addresses a preferred and an alternative server. Open the adapter settings by clicking on the appropriate button.
Cable and Wi-Fi connections can easily be differentiated in Windows 7 by the symbol: Cable connections are indicated by a plug, while the signal strength icon is displayed for Wi-Fi connections. As soon as you click on the Apple logo, the macOS system menu will automatically open. Not only can you make DNS server changes in the advanced network options, you can also, among other options, change your IP address or set a proxy server. If necessary, entered DNS server addresses can be removed using the minus symbol.
The text editor gedit is automatically installed on most Linux distributions, meaning you can start it right away using, for example, the command shown above.
You can also open the resolv. In the Ubuntu network menu, for example, you can find out which DNS server is currently responsible for name resolution. Prerequisites Decide whether you will use public IPv6 addresses that are globally aggregatable or if you will use a private address space. Configuration in IPv6-ready Network Systems For Windows 8 and Server , if you already have an unconfigured but IPv6-ready network infrastructure, you can still use IPv6 and configure IPv6 addresses in these situations: For home users with public IP addresses, Windows will try to establish a connection using the IPv6 transition technology Teredo.
Teredo will work only if the Windows machine is not joined to a domain and has UDP access to the Internet, with no firewall-blocking packets. If Teredo fails for home users with public IP addresses, Windows will use another IPv6 transition technology named 6to4 , which requires only a publicly routable IP address. It will then deliver these packets to IPv6 hosts, encapsulate the replies, and send those replies back. The following instructions are to statically address Windows and Windows R2 servers: Log on to the server with administrator rights.

I need to know why these names are not resolving If that's got nothing to do with not having IPv6 access I need to know why it is happening. It's probably a bug in nslookup.
