Inspired by the Packet Pushers Podcast  I setup my personal IPv6 tunnel to . Registration is free and the configuration is straightforward.

The first step is the registration and setup of a tunnel to our IPv4 address. Second step the configuration of the tunnel on our side. The webiste includes many examples of tunnel configuration, in my case Cisco IOS:

configure terminal
	interface Tunnel6
	description Hurricane Electric IPv6 Tunnel Broker
	no ip address
	ipv6 enable
	ipv6 address 2001:470:99:15::2/64
	tunnel source
	tunnel destination
	tunnel mode ipv6ip
	ipv6 route ::/0 Tunnel6

And this is the LAN interface of the router:

inte vlan 1
	ipv6 address 2001:470:98:15::/64 eui-64
	ipv6 nd ra interval 10

Notice that I reduced the router advertisement interval to speed up the configuration of the clients.

HE routes two prefixes through the tunnel, a /64 and a /48 so we can test one or more IPv6 subnets on the local site.

On my Win7 laptop I’ve just enabled IPv6 protocol on the interface (it was already enabled actually) and the ping is ok:

C:\>ping 2001:470:20::2

Esecuzione di Ping 2001:470:20::2 con 32 byte di dati:
Risposta da 2001:470:20::2: durata=124ms
Risposta da 2001:470:20::2: durata=151ms
Risposta da 2001:470:20::2: durata=147ms
Risposta da 2001:470:20::2: durata=110ms

Statistiche Ping per 2001:470:20::2:
Pacchetti: Trasmessi = 4, Ricevuti = 4,
Persi = 0 (0% persi),
Tempo approssimativo percorsi andata/ritorno in millisecondi:
Minimo = 110ms, Massimo = 151ms, Medio = 133ms

Notice that Win7 uses two IPv6 addresses for the interface, the first is created with EUI-64  method (RFC2464 ), the second uses privacy extensions (RFC4941 ).

We can verify online if IPv6 Internet access is working fine on websites like

So no more excuses, let’s start to practice IPv6 and be ready for it and join the World IPv6 Day .

You can either do a planned, careful migration, or you can do it in a panic, and you should know full well that panicking is more expensive."
