Re: Software and IPv6

Well, since there are so many programs out there that work perfectly well with ipv6, it is hard to think of any real show stoppers.

I can think of two major examples.

In certain circumstances, an IPv6 address can get embedded in a user's AuthAuthorty. In most cases, IPv6 is not actually routed by most of my customers (including a great many fortune 1000 companies), and if the Password Server is on another subnet, users can't authenticate.

In Panther, ipfw didn't understand IPv6. So 6 connections could get around any firewall rules.

Both of these are mostly fixed now, but this illustrates a trend of 6 not being taken into account by developers. So unless the networking personnel I'm working with are actually using 6 I always make sure it's turned off on the Mac.
