Is IPv6 a Problem or is it still in Beta?
Comments Off
Due to the high volume of people, I have thought of how best to go about describing my issue with my DSL router and why I”ve disabled IPv6!!! First off, I have a VISTA Premium System, with an OEM license. That isn’t nothing new. The problem is that if I use IPv6, I would constantly get no internet. I would always get local but not Internet. I didn’t know why until recently, and that was IPv6. It isn’t to say I don’t stop getting this. I still do but it is less of the problem. I could re-install the system and see if that fixes the problem.
Would that fix the problem?
Yes it probably would if it is a driver issue. I say it isn’t because if it was a driver issue I could just downgrade to an earlier driver, which there is none. I am going to guess that no one has done any new drivers for the IPv6 Since Vista came out. I don’t know why but with my DSL it has been an issue when I was on my cable. I recently switched, I had no problems.
Could it be my DSL Provider?
Network Connectivity and Vista’s TCP/IPV6
So I’ve been having problems with Vista and Network Connectivity. I’ve got a DSL modem that would from time to time just drop connection to the internet or at least I thought it was that. So I’d check the modem everytime this happenes. It would say I was connected to to the network but not be on internet. I went searching and found this really good forum discussion on Verizon and DSL. After reading all there was people were talking about the IPv6 protocol was the main culprit. So I figured I’d see what happens when I disabled the IPv6 Protocol from my system. It worked no more connectivity issues.
How do I disable the IPv6 Protocol?
In order to fix this problem you have to do some simples steps. Here is how I fixed it. Right Click > Select “Network and Sharing Center” > “View Status” for
either Wireless or LAN. > Properities

Does your DNS still have flaws?
Comments OffLate the week, I’ve had some concern with the DNS flaws with my ISP. So I’ve change to another DNS. So I went and did a test at:
Doxpara
So what does this mean when it says I might be at risk?
Very simple, your DNS provider is not randomizing the ports. I’ll get to that in a bit.
What is DNS?
The DNS is like a big Phonebook to where you tell it who you want to call, in this case go, and it finds the numbers and takes you there. It’s like telling a cab driver where you want to visit, just like telling the cab driver to come to my site. When you enter http://www.tech-linkblog.com into your browser, your telling DNS to go fetch the ip and direct your connection to this site.
So how can I fix this flaw?
Simple, You will need to direct yourself to OpenDNS. Has Fixed the flaw to help protect you. How do you use it? You will tell your system to direct all the DNS queries through that then your ISP DNS.
Vendors worried Vista IPv6 too slippery for managed networks

Researchers have raised new questions about the security of Vista’s IPv6 implementation. James Hoagland from Symantec and Suresh Krishnan from Ericsson wrote an Internet-Draft that calls attention to the Teredo protocol and the fact that many firewalls don’t understand this protocol, and therefore can’t inspect the packets embedded within it.Teredo is Vista’s last resort to connect to the IPv6 Internet. First, Vista looks for an IPv6 router on the local LAN. If so, the router will provide the Vista machine with IPv6 addresses and “native” (not tunneled) connectivity. If there is no IPv6 router, but the Vista machine has a public IPv4 address (i.e., not one from the 10-net or any of the other private address ranges from RFC 1918), it uses the 6to4 tunneling mechanism that embeds IPv6 packets in IPv4 packets. However, 6to4 can’t create IPv6 addresses from a private IPv4 address. Teredo, the third mechanism, is able to do this, so if you’re behind a network address translator (NAT) then Vista uses Teredo.
