Disable IPv6 Windows 7

Disabling IPv6 is non a good idea – IPv6 has been here for some fourth dimension now and most ISPs take no problems whatsoever resolving IPv6 IP'south. Only disable it if you know what yous are doing

Why should I disable IPv6?

ane. Resources:
Disabling IPv6 might exist a good thought, because the protocol consumes boosted CPU time and organization memory every bit well as bandwidth. Of grade the resource usage of an internet protocol is pretty depression, but why would you waste resources for 2 cyberspace protocols, 1 is already enough.

ii. Security:
Enabling another internet protocol might too increment your vulnerability to possible exploits. If there is going to be an IPv6 exploit and you are but using IPv4, you won't exist affected.

Why shouldn't I disable IPv6?

1. IPv6 enabled by default + preferred choice:
IPv6 is not only enabled past default in Windows Vista and Windows vii, merely is likewise the preferred protocol in Windows vii. If you perform a dnslookup and the query returns both IP address (one IPv4 accost and 1 IPv4 address), Windows vii will automatically use the IPv6 address. Why is that?

2. Become used to the future of the net
Practise you lot know that IPv4 exhaustion inaugural is ticking constantly? Nosotros volition be running out of IPv4 addresses very soon, and and then IPv6 will be the future. Then, get used to information technology, you will take to anyhow!

iii. Advanced security layers
The newest internet protocol is supposed to make the cyberspace a safer place. Advanced security layers brand IPv6 more secure than IPv4 (that'due south what they say).

4. IPv6 Network Discovery
A built-in network service requires IPv6: Network Discovery. If you want to access an IPv6 ad-hoc network to share files with another PC you will non even find the other computer in the network. Additionally, many of the new switches and routers support IPv4 and IPv6 protocols and you might not be able to come across some IPv6-only devices on a network. Of course, you tin can e'er enable IPv6 when yous join another network or play with friends over LAN.

1. Disable IPv6 for LAN adapter & interfaces

one. Step Open up the "Control Panel" and and so the "Network Sharing Middle":

Network Sharing Center in Windows 7

ii. Step Click on "Modify adapter settings":

Change Network Adapt Settings in Windows 7

Local Area Connection in Windows 7

iv. Step Uncheck "Internet Protocol Version half-dozen" and click on "OK":

Disable Internet Protocol Version 6

2. Disable IPv6 for tunnel adapter & interfaces

If you lot are non familiar with editing the registry, I created a .reg file for yous that yous tin can apply to add together the registry key and disable IPv6. To verify that this file is ok, open it with a notepad once, information technology simply includes the post-obit lines:

Windows Registry Editor Version five.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters]
"DisabledComponents"=dword:ffffffff

Link: Download Disable IPv6 Registry Tweak (.reg file)

Alternatively, yous tin can simply practice information technology yourself, information technology shouldn't exist likewise difficult:

1. Step Open up the registry.

Regedit.exe

2. Footstep Uncollapse [HKEY_LOCAL_MACHINE\Organisation\CurrentControlSet\Services\Tcpip6\Parameters\]

three. Footstep Next, nosotros create a new 32-flake registry primal: "DisabledComponents":

By the way, even if you are on 64-scrap arrangement you take to create a 32-bit registry central only, considering it only reflects the size of the registry central. A 32-bit registry primal can shop a maximum value of ii,147,483,647.

Create 32-bit DWORD registry key

4. Step Enter: "DisabledComponents" when prompted for a name.

DisabledComponents Registry Key

v. Footstep Double-click the newly created registry key and re-create and paste the value: ffffff (8f)

6. Step Restart your PC and you are done: You just disabled IPv6 in Windows 7!
