Protect Your Pre-1997 IP Address
CWmike writes "With IPv4 space running out any day now, is your legacy IP address space safe? Marc Lindsey writes that if your company obtained its IP address space before 1997, you have probably received several letters from the American Registry for Internet Numbers encouraging you to enter into a contractual agreement to protect the IP address. But should you sign it? Be careful — there are several issues you should consider before signing up for this, writes Lindsey, who offers a deeper look at the issue."
Save some time, 4 pages is silly given the content.

Not the same. My phone number is published, my IP address isn't. I've moved IP addresses for my server four times in the last year. I set the DNS TTL to a few seconds, wait for old caches to expire, update it to the new address, and then reset the TTL to a longer value. No on notices.
I just moved to a new mobile phone company too. My SIM ID, which is used to uniquely identify my phone on the network, changed. My phone number was moved across. The phone number is just an entry in a database that maps to a SIM ID, just as DNS maps to IP addresses (actually, DNS can map to all sorts of other things, including geospacial coordinates and telephone numbers).
That's why we have these layers of indirection - so the low-level ones can be changed easily.

I'm sorry to have to say this to you like this, but you have no idea what you're talking about. Did you think about the infrastructure where you connect all those PC's?. Take Cisco in the Datacenter for example, current status is:
Routers and switches support IPv6 (excluding Nexus 1000V)
Firewalls (ASA) support IPv6
Firewall Service Modules (Cisco's Datacenter firewall solution) don't support IPv6 in transparent mode, don't support failover in IPv6, don't support IPv6 on hardware (which make them useless for real traffic)
Load Balancers (ACE), no support
WAN optimization, no support
Ironport, no support
etc.
And even if this support comes, in most cases it's not just a simple software update, you have to update the hardware and you're talking 10's of thousands of dollars for each. So believe me, it's not that easy, even with the will and the money, in some cases there is no even offering from the vendors at this point, which is shameful.
We do?
Actually no we don't, because customers (that would be you) aren't willing to pay the actual cost of equipment. Upgrades are something that happens when the old stuff is dead or 5 years has passed (the time it takes to write it off), whichever comes first.
The world is consuming a /8 - 16 million addresses - roughly every 3 weeks.
Your piddling 65k addresses for a class B? 2 hours, tops.
