Re: IP Address - purchase from an upstream?
We are an ISP so we have to schedule appointments which each of these customers, assist them in making changes to their IP schemes which they generally don't remember how they are set up. I first changes all customers who didn't have any static IPs and those were all moved without issue. It is the remaining static customers who have been around for many years that are taking so much time. They are also very resistant to this. |

| I don't know too much about IP addressing, but have you contacted ARIN to see if they even allow transfer of IP addresses from one of their carrier customers to another? If ARIN won't support it, or if it's not permitted, then you're done. Then ask whoever would be the new holder of the IP addresses if they have a procedure for accepting them -- if they have no process or procedure for accepting transferred IP addresses, then you're done, too. My understanding is that the industry practice is to not permit IP address transfer -- I don't know if it's just an anti-competitive thing, or if there is an industry constraint. Do an internet search on "IP address portability" and you won't find anything encouraging.
In the voice world, transfer of toll-free numbers and local number portability all were not possible until the industry created a middle-man type clearinghouse that facilitated inter-carrier number transfers and updated network switches nationwide. Until such an IP address portability clearinghouse is developed, with the additional complexity of instantly updating network routers worldwide, you might be stuck. |

said by synergizer  :It is the remaining static customers who have been around for many years that are taking so much time. They are also very resistant to this. And with good reason too. If they have a static IP address it likely means they need it, not just because they wanted it. For them, changing the IP address means A LOT more than you simply coming out and assisting them in changing their routers and such. They might have a website/email server they are hosting that relies on that IP address. Or they could have VPN tunnels to other locations that rely on that IP address that also need to be updated.
As you know, DNS takes 72 hours to fully propagate. Think of it this way, their website and email could be down for three full days because of a change you made. Don't get me wrong, I'm sure you have very good reasons for doing this and you might not be able to get out of doing it so there isn't much you can do about it at this point. I'm just trying to point out to you why they are resistant.
My suggestion would be to try and schedule all your static IP cut overs for Fridays. That way they are only "down" for the weekend. Most places aren't open on the weekend so this should be a good time for most of them. If you could run dual addresses that would be even better. Let them have both the original and the new address for say a week. That would give them time to make any changes and let DNS propagate without being "down" as the same equipment would respond no matter which IP was handed out by DNS. Beyond that, expect a lot of unhappy customers. |
