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. -Bill

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. -- "Since when is skepticism un-American?
