"I haven't heard of that policy, but one of the goals with IPv6 is to have a hierarchical address structure, with the resulting reduction in routing tables. Using addresses from other parts of the world would tend to go negate that."

<myname>.broker.freenet6.net IPv4 address
1 Reply
When I do a host look up on my freenet host name, I get both an IPv4 and IPv6 address. The IPv6 address points to my end of the 6in4 tunnel, but the IPv4 address points to something that has nothing…Continue

Is the Montreal server down?

I'm not getting a tunnel set up on my firewall, which is configured to use the Montreal server. My notebook, which is configured to use any server, is able to get an IPv6 address, but it's on the…Continue

James Knott replied to Maninder Singh's discussion 'Can someone verify if the addressing scheme used in this network diagram is correct?'"Of course, with 16 network bits to play with, he can have up to 65K subnets. It shouldn't be too hard to aggregate with that many available."
James Knott replied to Maninder Singh's discussion 'Can someone verify if the addressing scheme used in this network diagram is correct?'"Is it possible to create a larger image? The one you provided is not readable on a 1920 x 1080 display. Why do you have 5 routers before you get to some hosts? Routing works the same, whether IPv6 or IPv4. As far as the…"
James Knott replied to David G. Miller's discussion 'Can't route traffic between LAN clients and gateway router'"I don't know what you use OpenVPN for, but I found after I made my network available via IPv6, I no longer needed OpenVPN. However, everything thing I do on my home network from remote sites is carried via ssh or ssl, so it's already…"
James Knott replied to System Error Message's discussion 'PC with gogoclient with home and remote aceess inaccessable remotely'"I have no idea what ask4 is, but if you're connecting and getting an IPv6 address, your IPv6 address should be beyond reach of the university network. I have found that broker.freenet6.net to be useless for accessing my system. Try…"
James Knott replied to Rupesh's discussion 'internet access on purely ip v6 network'"Are you referring to my suggestion with the hosts file? No it doesn't change anything other than name resolution. You wanted a way to test via IPv4 or IPv6. My suggestion merely provided a means where you could create a test…"
James Knott replied to Rupesh's discussion 'internet access on purely ip v6 network'"You are not disabling IPv4 through the hosts file. You are simply providing a host name with no IPv4 address. This is why I said to create a dummy name, so that it cannot be found by your normal DNS. If you, for example, had use…"
James Knott replied to Rupesh's discussion 'internet access on purely ip v6 network'"If you cannot ping -6 google.com, using DNS, then you have an IPv6 issue that must be resolved."
James Knott replied to Rupesh's discussion 'internet access on purely ip v6 network'"I just tried adding googggle.com to my hosts file and ping worked fine. Does it work when you try using the real name via DNS, with both ping -4 and ping -6?

James Knott replied to David G. Miller's discussion 'Can't route traffic between LAN clients and gateway router'"You might want to check out that "IPv6 Essentials" book I mentioned in the blog section of this site. It contains a lot of useful info."
James Knott replied to David G. Miller's discussion 'Can't route traffic between LAN clients and gateway router'"Is this computer used for anything else? If might be easier to start from scratch and reinstall Linux, then install the gogo client etc."
James Knott replied to David G. Miller's discussion 'Can't route traffic between LAN clients and gateway router'"I see Scientific Linux is based on Red Hat. So perhaps someone with RH experience can help here. All my experience is with openSUSE.

James Knott replied to David G. Miller's discussion 'Can't route traffic between LAN clients and gateway router'"First off, why do you have so many routes listed? You normally don't have to manually add routes. The gogoc client should provide the route back to the Internet and radvd provides default route and subnet info to the other computers…"
James Knott replied to Rupesh's discussion 'internet access on purely ip v6 network'"I don't know what operating system you're using, but with Linux you have to use ping6, not ping for IPv6. Also, when I suggested that I was thinking you'd create a name that wasn't available via DNS. This is to avoid…"
James Knott replied to David G. Miller's discussion 'Can't route traffic between LAN clients and gateway router'"That doesn't make sense. All devices on the lan appear to be on the same subnet and would have the same /64 subnet. A computer would normally always use the same address, no matter where it's connected. If it determines…"
James Knott replied to David G. Miller's discussion 'Can't route traffic between LAN clients and gateway router'"Once again, there is no such thing as local routing. Routing is only used when you're going off your local network. IPv6 uses neighbour discovery to determine the MAC addresses of other devices on the local network, instead of arp…"

Sybex Cisco Certified Network Associate book. Wait before buying
I have been studying this book with the intent of obtaining Cisco CCNA certification. However, I noticed several errors in the chapter on IPv6. I have been in contact with the author about this and he said he will be updating that chapter to correct the errors I pointed out. I have the Deluxe Edition, 6th edition, revised and updated for 2011, but I believe the errors may also be in the 7th edition. So, if it's on the shelf now, it will likely contain those errors. Wait for one with a…

Good IPv6 reference book
I have noticed that many problems people experience are due to not understanding IPv6 and how it differs from IPv4. There is one book that contains a lot of useful IPv6 information. It is IPv6 Essentials, by Sylvia Hagen and published by O'Reilly. It's available in both paper and e-book versions. What's nice about the e-book version is purchasers are entitled to free updates. I refer to this book…

IPv6 port scan site
I don't recall if I mentioned this before, but there's an IPv6 port scan site, which you can use to check your firewall on IPv6.
