Consumer Network Products


The only consumer class gateway/router under USD $200 I have found with good IPv6 support is the Apple Airport Extreme. Over USD $200 is the new Cisco RV220W.

[February 2012] There are more routers showing up with various levels of IPv6 support. Tunnel broker support (Hurricane Electric and SixXS) remains scattered.


[Feb 2012] Canon's latest printers apparently support dual-stack. I have not found anything about HP.

Network Storage

While you can find consumer level NAS devices that can be assigned an IPv6 address, other networking software needed to make everything seemless (mDNS for example) is not quite there. Samba appears to be working well in dual-stack.

Other Fun Things

Juniper Networks has an outstanding bug in their software that ignores IPv6. For companies that don't allow split-tunneling (while you are connected to the VPN, you can still use your local network, Internet-destination traffic goes through your local ISP, etc) the IPv6 route is left alone so you can effectively split tunnel between IPv4 and IPv6.

Google Webmaster Tools does not verify IPv6 sites. Lame.

[Update June 2011] Webmaster tools now verifies IPv6 only sites and grabs sitemaps.

[Update November 2011] Google now returns results for IPv6 only sites.

mDNSResponder only works over IPv6 on OS X. FreeBSD and Linux kernels are missing some parameters to allow IPv6 mDNS to function properly.

World IPv6 Day is June 6, 2012. Companies can turn on dual-stack sooner if they want.

[February 2012] Running tcpdump and noticed that IMAP and SMTP traffic to Google now runs over IPv6.

[February 2012] Google, Facebook and YouTube are both returning AAAA records for their www sites. Guess they didn't want to wait until June. Way to go! Apple however uses Akamai and apparently Akamai is not yet ready.

More soon...
