Hello,
Can anybody give a short list of Disadvantages/Advantages of IPv6 in
Linux?
(comparing to IPV4).

I am more interested in disadvantages (because I think I know more
about the
advantages).
The only disadvantages I could think of are only these 3:

1) Currently there is no support to LVS in the linux kernel.

2) You need to port applications to IPV6 .

3) You need tunnels when you are working against IPV4 machines.


I would appreciate if anybody can add to this list of
disadvantages.

Regards,
Ian
