Re: IPv6 (was: on WEB400 list)

Here is what I am hearing from the "experts" (that are on TWiT anyway). IP
V4 is a problem. However, as addresses become limited companies will find
ways around the problem. Maybe residential ISPs will switch to NAT routing
and only allocate an external IPs by request (and payments). Mobile devices
could sit behind an IP V6 (or 4) NAT router and work just fine on the WWW.
IP V4 is very difficult to eliminate; it is used in the third-world counties
were they can't afford the upgrades needed. Even if we get US government
mandate here, there are problems all around with infrastructure and outside
of our jurisdiction. It isn't as easy as plugging in a new router or new
firmware patch.

After hearing this, I have changed my position more towards, "I don't care".
If I need to worry about IP somewhere in programs, I'll probably code for IP
V6 just so I don't have problems in the future but I won't be switching
anything over any time soon.

I'm curious ... is IPV6 really important for internal corporate networks?

I ask this for two reasons ... 1) One of the requests we've had for
Implementer is to support IPV6 in our comms framework (luckily it's all
implemented using service programs so I won't have to rejigger all the
applications), and 2) I'm just darn curious.

I can understand it's theoretical need on the internet ... but once you've
bridged into a private network, does any organization have more machines
than the private A class block (10.x.x.x) can't handle?

Even on the public internet ... where are all the IP's going?  I keep
hearing reference to the proliferation of mobile phones and network
appliances causing the IPV4 address space drain ... but my iPhone (AT&T) has
a 10.x.x.x address assigned to it.  My Tivo, iPad, VoIP, etc, all have
private addresses hidden behind my router (of course It's always been my
opinion that everyone should have a router, even if they only have a single
computer).
