Using IPv6 only

[mylo]

Hi all,

what happens if I would use IPv6 only (no more IPv4) and how can I do/force ths?

theoretically you shouldn't see any difference
But you will not reach many websites and services (like siduction.com) - ok there is ip4 in ip6 (http://en.wikipedia.org/w/index.php?title=IPv6#IPv4-mapped_IPv6_addresses), but I never played with it. An other problem is, that some programms can't handle ipv6 addresses in configs or from user input.

To have a clean ipv6 system you first need a ipv6 address/prefix (any carrier, that gives you an ipv6 prefix), than delete all ipv4 adresses from your system and your done.

Nowadays it is the best to have a dual stack and have a ipv4 and ipv6 address. If your carrier doesn't support ipv6 use a tunnel.

Oh and keep in mind, that ipv6 has no NAT, so be sure that you have a working firewall.
