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

"No, use the host command.  You can use it to find the IP address of a host name or the host name of an IP address."

James Knott replied to Carlo Regondi's discussion 'Address issue and Synology config'
"Perhaps you should try something like Wireshark to see what's happening.  If you can reach it with ping, you should be able to reach it with any protocol, provided it's not blocked by a firewall. "

"Is the computer that has the tunnel set up as a router?  If not, other devices will not get an IPv6 address.  The method for configuring routing depends on whether you're running Linux or Windows.  In Linux, you can see if other…"

"Did you get a single address or a prefix?  If you have more than one device, you need to get a prefix for your own network.  That way, every IPv6 capable device will be able to get an IPv6 address.  If you use an anonymous connection,…"

James Knott replied to Joakim Leufstedt's discussion 'Setting up tunnel on Debian 7.8'
"The server doesn't give out anything.  Either it has an IPv6 address or it doesn't.  Are you perhaps referring to the DNS lookup?  If so, you have to configure the DNS server with an AAAA record, so that the host name…"

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.
