RE: v6ops:IPv4 vs. IPv6 operational costs


I need to take a closer look at 6to4. Thanks.

It may be a long time before even a moderate portion of hosts are dual-stacked, in the sense that IPv6 is enabled on the hosts and intermediate networks route it and DNS supports it. At least in the US.

You may or not. You may rely on translation (some form of NAT, yes), or tunneling - 6to4, for instance. Or you may just consider that most of the nets are dual-stacked.

It's my understanding that if you run an IPv6 only network, you will still need a NAT (e.g., NAT-PT) anyway to talk with v4 hosts.

Pekka,

Looking a few years down the road, assuming that bulk of the bleeding is
over, will operating that network be simpler, easier, cheaper than
operating a network with private addressing today?

How painful is introducing new applications behind NAT/ALGs? What
percentage of an IT department's budget spent on issues relating to
private addressing?

I've not but I'd be interested to see _real_ calculations.

I assume from your wording that you're referring to an IPv6-only
network.  If so, my suspicion is that the costs can be high as you
need to live on the bleeding edge, i.e., are the one that'll find the
bugs, need to get a lot of consulting to get the network to work as
v6-only, etc.
