[arin-discuss] Policy question

[Nicholas Hoague]

Ok now that’s hilarious! Honestly I’ve done the same. We recently acquired a /24 and verified it was clean we spent about $6600 and had no problems. Then potted them to Bigleaf for our redundancy solution.

Just chiming I’m on the responses here. It wasn’t bad at all, but planning is utmost importance. I had about a month of time lines planned so my customers would have little to zero knowledge / impact of our massive /24 to /24 conversion.

Once upon a time... I moved my entire data center from one city to another by physically driving the gear about 3 hours. At the time, my IP addresses were leased from my upstream provider, but I used the same provider at both ends, so no renumbering was necessary, which was awesome! Side note... even though we didn’t experience any problems or damage, I don’t recommend piling servers and portmasters loosely in the back of a van without securing the lot. You learn to ignore the crashing sounds coming from behind you as you’re driving.

Is there any requirement for an ISP to allow transferring IP's in use by a customer to another ISP?

Not only is there no such requirement, there’s actually pretty strong pressure not to allow it.

It causes fragmentation of the IP routing table which is considered problematic from a router memory perspective. Less so these days than in some years past, but still an issue.

In the telephone world, NANP requires local number portability such that a customer isn't beholden to a single carrier.

Changing phone number involves changing stationary, business cards, and all kinds of things that communicate with external parties and are hard to update.

Changing IP addresses is a pain, but if you’ve used DNS properly, it’s pretty easy to know where you need to update it and it’s not that problematic in most cases.

Case example: Long standing customer at a data center with a /24 IP block wants to move to another datacenter.

As a general rule, number portability isn’t going to be very useful here anyway.

Unless the customer wants prolonged down time, they’re going to want to move in stages and have some equipment at the new datacenter running in parallel. That means new numbers at the new datacenter anyway because the old numbers need to keep running and cutover is (usually) best accomplished after testing by DNS changes.
