[NTLUG:Discuss] IPv6 - any one using it?

[Jack Snodgrass]

Is there any advantages / benefits to using IPv6? I see a lot of
support of it... I haven't
experienced any real-life usage with it. 

Are any major/public sites like google, yahoo, ebay, etc accessible via an 
IPv6 IP address or would use use an IPv6-IPv4 gateway thingie? 

Currently, I use several tunnels to link to different systems. I'm using 
vtun to make the tunnels. Once I have the tunnel set up, and set up the
routing beteen the networks to go over the new tunnerls, I can do 
2-way traffic between the private networks. Can I use an IPv6 network 
to seamlessly connect the networks so it looks like one, big private 
network ( as opposed to several private networks with complicated 
routing ) 

Thanks - jack
