The Internet’s IPv4 dashboard gas barometer is blinking abandoned at alone 5% larboard in the tank, isn’t it nice that Windows 7 supports IPv6? Well, array of, supports it. jvc gy-hd110u battery

Actually, Windows 7 does a appropriate job of acknowledging IPv6. It absolutely does abundant more good than the ones that came before, but it still has some quirks.

The one that springs to my apperception aboriginal is that Windows Server 2008 and Windows 7 both still use accidental interface identifiers back creating its IPv6 addresses. While Windows 7 is now certified as actuality IPv6 Ready, it’s not absolutely on ambition by default.

That’s not how IPv6 addressing should work. Instead, an IPv6 device should auto-configure its address with the Neighbor Discovery Protocol (NDP) to determine its network and interface identifier and to form the computer’s 128-bit IPv6 address. IPv6 addresses assignments are spelled out in these Internet Engineering Task Force (IETF) documents:

•IETF RFC 2373, IP Version 6 Addressing Architecture
•IETF RFC 2464, Transmission of IPv6 Packets over Ethernet Networks
•RFC 4941, Privacy Extensions for Stateless Address Autoconfiguration in IPv6
Microsoft mixed up how the interface identifier should be created even though Microsoft engineers helped write RFC 4941. Oh well. Still, you can force Windows 7 to use the correct method by issuing the following command from a DOS prompt:

netsh interface ipv6 set global randomizeidentifiers=disabled

I acclaim that you put this in accumulation or login book to run this as an automatic command on all your fresh Windows 7 installations. Doing so avoids any accessible IPv6 arrangement problems with added Windows 7 systems and with IPv6 address-compliant networking accessories such as Cisco Catalyst Switches.

It would additionally be nice if Windows 7 accurate SEcure Neighbor Discovery (SEND) (RFC 3971 http://www.start-battery.com). SEND is the added defended adaptation of NDP. You can use it to verify that the accessories on are accurate on your LAN. jvc gr-d31us charger

Unfortunately, while afresh Microsoft helped address this specification, itscomputer application engineers haven’t implemented it. Some above arrangement vendors, such as Cisco and Juniper, already abutment it. I achievement that Microsoft will add it into Windows, forth with the actual acclamation scheme, in the abutting Service Patch (SP) for all its operating systems. After all, the eventually we adamant out any abeyant accomplishing problems and aegis worries with IPv6 the better.
