I want my own IPs

I have recently been turned down by ARIN for an
address block. I currently have 4 /24's from ISP's and
would like IP independence. How do I convince ARIN to
give me a block -- /20 I guess? The form I filled out
does not make it easy.


Try chaining yourself to the front door.

Form is a form. If you can't complete the ARIN form, that means you don't
track well your current IP allocations, and you aren't qualified to be
allocated new IP addresses.


It's not a matter of convincing, it's a matter of demonstrating need.

If you're actually _using_ the four /24s, you can demonstrate a need for a
/22 today. So a good first step would be to use the four /24s until
they're full. Second step would be to apply to ARIN for a /22 to replace
them. Renumber into that. Then keep applying to ARIN for more space as
you need it.


I ask this just for personal edification, but can you ask ARIN for a /22?

I thought the lowest they would go is a /21 for multi-homed organizations.

Aside from everything else that's been mentioned in this thread,
keeping really good records of your network is very helpful (it's
helpful for other things as well, of course). In our case, pretty much
all of our services are managed, and all our DNS records etc. are
generated, so it's very easy for us to generate lists of websites on a
particular IP, basic lists of IP assignments, or whatever, since the
information is already there in our database.

Obviously if we were doing more sub-assignments to other
organizations, it would be harder to make sure we had all that
information available in a reasonably consistent (and up to date)
form.... however I imagine it's possible.

If you keep all that information in some sort of database from the
start (and for 4 /24s, it's not /that/ much information), it should be
relatively easy to write some quick and dirty scripts to provide ARIN
with the information they need, and you'll be more easily able to
provide the information as your network grows.

ARIN is picky about certain things, but I've found them to be pretty
reasonable and efficient as long as you can provide them with the
information they need, and (of course) as long as you can actually
justify your request.

Of course, just because you want to have IP independence probably
isn't going to be good enough for them - you'll have to demonstrate
that you need to be multihomed or have other needs that require you to
get PI space.

They probably gave you a reason when they turned you down - perhaps
you need to pay attention to what they told you, and resubmit your
application after correcting the problem(s) that caused them to turn
you down.

And it's possible that you may just need to wait longer until you can
really justify a larger allocation.
