If a tree falls in the forest and no one is there to hear it, does it still make a sound? Of course it does. Hmm, interesting thought Slyldawg, however the definition of consequence is "a result or effect of an action or condition" it does not require the 'observance' of that effect or condition. If consequences are never noticed, don't they fail to rise to the level of consequence? And wouldn't we know by now? I have a saying: You know as much after you say maybe, as you knew before you said it. If you had voiced that you had a security concern with leaving it on then that might be a different story. I agree with those that say turning it off is not likely going to solve any issue you are having. I think the question you should be asking: "Is it BEST practice to turn it off"? Turning it off my not have any benefit, but it could conceivably cause unintended consequences that could potentially go unnoticed. I have not had any DNS issues since doing that, except for the pseudo-client.
Is it good to disable ipv6 on mac windows#
Now for all of my networks, I add the static IPv6 address of the DC to DHCP for the DNS server IPs fed by the Windows DHCP. If I disable IPv6 on the router, wireless dies! They won't buy a good firewall (WatchGuard) and separate wireless AP (UniFi) that I recommend to all of my clients, which is why I call them a pseudo-client. The reason for having that Mickey Mouse setup is that their cheap consumer-grade junk wireless router REQUIRES IPv6 when its wireless is enabled.
I set the IPv4 DNS and IPv6 DNS servers statically on the workstations so that they won't query and get the router's information. The "fix" (just a bandage) was toĪdd a static IPv6 address to the DC and add that to the DNS server IPs fed by the Windows DHCP server to the workstations because the client was too cheap to listen to me and buy a real LAN firewall and a separate wireless AP.
With both having DHCP on, the DC won for IPv4 queries and the router won for IPv6 queries That caused issues because the workstations queried IPv6 DNS first and of course the router had no clue about LAN resources. The only issue I ever had that disabling IPv6 "fixed", or rather MASKED, is when a pseudo-client replaced their LAN router without consulting me and it had DHCP enabled.īecause Windows Vista and newer prioritize IPv6 over IPv4, the workstations got the router as their IPv6 DNS server, but they got the domain controller DNS server as their IPv4 DNS server.
Is it good to disable ipv6 on mac windows 7#
By leaving IPv6 enabled, you do not disable IPv6-only applications and services (for example, HomeGroup in Windows 7 and DirectAccess in Windows 7 and Windows Server 2008 R2 are IPv6-only) and your hosts can take advantage of IPv6-enhanced connectivity. Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled. Moreover, applications that you might not think are using IPv6-such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail-could be. If IPv6 is disabled on Windows 7, Windows Vista, Windows Server 2008 R2, or Windows Server 2008, or later versions, some components will not function. Because Windows was designed specifically with IPv6 present, Microsoft does not perform any testing to determine the effects of disabling IPv6.
This is not true.įrom Microsoft's perspective, IPv6 is a mandatory part of the Windows operating system and it is enabled and included in standard Windows service and application testing during the operating system development process. Others might disable it because of a misperception that having both IPv4 and IPv6 enabled effectively doubles their DNS and Web traffic. Many disable IPv6-based on the assumption that they are not running any applications or services that use it. It is unfortunate that some organizations disable IPv6 on their computers running Windows 7, Windows Vista, Windows Server 2008 R2, or Windows Server 2008, where it is installed and enabled by default. What are Microsoft's recommendations about disabling IPv6?Ī.
