I have a Windows 7 64 Bit machine, and I cannot find a way to disable the IPv6 Loopback. I looked at the article at How to disable IP version 6 or its specific components in Windows and shows how to set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents to various values - but none of these seems to disable IPv6 Loopback As far as I know, we couldn't disable IPv6 loopback interface, even when we configure the registry key to disable IPv6, it is except for the IPv6 loopback interface. I think we need to consider how to unbind the application to the IPv6 loopback interface, if it is a third-party application, you can contact the provider to check how to bind it to specific interface
Next, execute the below command to disable IPv6 on a specific network adapter. Replace NetAdapterName with the actual network adapter name you got with the earlier command. Disable-NetAdapterBinding -Name NetAdapterName -ComponentID ms_tcpip6 (Optional) To turn off IPv6 on all network adapters, use the below PowerShell command If you are using Network Manager to manage your network settings, you can disable IPv6 on Network Manager as follows.

These instructions work in Windows Vista, Windows 7, Windows 8, Windows Server 2012 To disable IPv6 runtime, append 1 to the below sysctl configuration files # echo 1 > /proc/sys/net/ipv6/conf/default/disable_ipv6 # echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6. Next you can verify, you will not see inet6 when you list the available interfaces and their IP addresses with ip a comman
Type 010 to disable IPv6 on all nontunnel interfaces (both LAN and Point-to-Point Protocol [PPP] interfaces). Type 001 to disable IPv6 on all tunnel interfaces. These include Intra-Site Automatic Tunnel Addressing Protocol (ISATAP), 6to4, and Teredo. Type 011 to disable all IPv6 interfaces except for the IPv6 loopback interface . To disable IPv6 you only have to input 3 commands: sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1 sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1 sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1. You can check if it worked using: ip a. You should see no IPv6 entry
Issue the command sysctl -w net.ipv6.conf.default.disable_ipv6=1; To re-enable IPv6, issue the following commands: sysctl -w net.ipv6.conf.all.disable_ipv6=0. sysctl -w net.ipv6.conf.default. 5. The issue was that ipv6 was disabled in sysctl. Once I enabled, both eth0 and lo had ipv6 addresses. sudo sysctl -w net.ipv6.conf.eth0.disable_ipv6=0 sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=0.

By default, Windows 7 and Windows 2008 R2 resolve the localhost host name to the ::1 IPv6 loopback address, rather than the 127.0.0.1 IPv4 loopback address. Windows will resolve localhost to ::1, even if you have disabled IPv6 on all of the installed network addapters. This doesn't just affect MySQL. This affects any TCP/IP client/server. To forbid ipv6 from working actively even when ipv6.ko is loaded, add a line in /etc/modprobe.conf: 2. Add a line onto /etc/sysconfig/network: 3. Disable ip6tables service: 4. Reboot the server.

In fact, over 50% of all Facebook's US traffic is now IPv6, and over 30% of Google's worldwide traffic is IPv6.
IPv6 loopback interfaces share the same IPv6 address space with VLAN configurations. The maximum number of IPv6 addresses supported on a switch is 2048, which includes all IPv6 addresses configured for both VLANs and loopback interfaces (except for the default loopback IPv6 address, ::1 /128). Each IPv6 address that you configure on a loopback interface must be unique in the autonomous system. In Windows 7, to disable IPv6 tunneling over IPv4:.

If you're connecting to localhost (::1 / 127.0.0.1), you're not using the network card that your server has, but rather like a virtual card that windows has. Your loopback interface can accept traffic, but your system cannot send traffic from loopback because output policy does not allow this. Because of this you need to define output policy: iptables -P OUTPUT ACCEPT Or define rule only for loopback interface: iptables -A OUTPUT -o lo -j ACCEPT The second rule is needed for dropping packets that comes to NOT loopback interfaces (e.g. from LAN.
