Don’t have IPv6 connectivity to your home or office network? Have you asked your ISP about getting IPv6 and they can’t give you a timeframe?
Don’t despair! One way you can get IPv6 connectivity for your home office is to set up an “IPv6 tunnel” from your network out over your IPv4 Internet connection to an “IPv6 Tunnel Broker” service that will then connect you out to the rest of the IPv6-enabled Internet.
An IPv6 tunnel can work quite well and was in fact what I used for most of two years until my local ISP just recently provided native IPv6 connectivity. The good news, too, is that there are IPv6 tunnel broker services that are available to you for free, operated by companies and organizations that want to expand the use of IPv6.
