Ok ... not sure if this was done before but I am curious to find out people's opinions on IPv6...I have heard pros and cons, and even the con of ISPs being able to ban a IPv6 address, thus pretty much rendering a NIC useless since the addy is based on the MAC for the card....

So, in a meeting today I was "told" we had to convert to IPv6 by 2008, nice eh...but I want to know what is the opinion of the average LQ forumer...

What do you know about it's pros and cons, how it handles for a end user surfing the web to a server which runs production modelling and a heavy I/O postGresql DB, NTP and FTP issues, NAT masquerading, etc...I can get the average answer from google, and the usual pros and cons, but if anyone has any inside information, personal experience etc...that would be useful

Thanks

From my personal experience IPv6 is great. I used it extensively through various tunnel brokers two years ago. But there is a slight problem that not a lot of software supports it (there is apache IPv6 though, but php for IPv6 resolving was broken at that time). However, the number of IPv4 addresses can't fulfil whole world so there is no other choice. I stopped because IPv6 usage does not increase in my country until pressure is made (just nobody uses it).

IPv6 is, in my experience, much better and a tad bit faster than IPv4. I noticed IPv6 through a tunnel broker requires fewer hops than IPv4. See my results here.
