RDNSS possible with gogo client

I've come across an interesting problem with Android devices on my network.  While they generally work well with IPv6 on my network, one issue is the WiFi won't connect if the IPv4 DHCP server is…Continue

ShowIP

One useful browser add-on I've come across is called "ShowIP".  It displays the IP address for the web site you're viewing, whether IPv4 or IPv6.  It's available for Firefox, Seamonkey and Chrome…Continue

Subnet address changes again

I had problems with IPv6 again yesterday. It appears my subnet address was changed again.  I find this very annoying, as I have to reconfigure my firewall and also update the DNS server with the new…Continue

gogoClient on Linux and DNS

I have a Linux based firewall where I run the gogoClient.  One thing I've noticed is that if the tunnel is down, that computer will not connect to a DNS server.  I have 2 DNS servers, with IPv6…Continue

RDNSS possible with gogo client

I've come across an interesting problem with Android devices on my network.  While they generally work well with IPv6 on my network, one issue is the WiFi won't connect if the IPv4 DHCP server is down.  The Android support guy insists RDNSS is necessary to assign a DNS server address, but I have just been using the IPv4 DHCP server to hand out an IPv4 DNS server address.  Is there any way to use RDNSS with the client?  I've tried following the hints in the gogoc-radvd.conf, but no luck.  If I…See More

James Knott replied to Wesley Santos's discussion 'userid & password for Freenet6'
"One thought.  You mentioned it works in Windows.  Are you trying to run it on both at the same time?  With an authenticated account, you're assigned static addresses and you can't have them assigned to more than one device."

One useful browser add-on I've come across is called "ShowIP".  It displays the IP address for the web site you're viewing, whether IPv4 or IPv6.  It's available for Firefox, Seamonkey and Chrome browsers.  I don't know about others.  With ShowIP, you can tell at a glance whether the site is on IPv6 or IPv4.See More

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.
