- Nowadays Internet became classless community and the notions of "A (B, C) network" class became obsolete. Instead, new IP addressing scheme called CIDR (Classless Inter-Domain Routing) and the new notion "block of addresses" have emerged. A CIDR IP address looks like a normal IP address except that it ends with a slash followed by a number, called the IP prefix.
- You can register your autonomous system if you are connected to at least two different providers (ASes) and you need to switch between them from time to time. That is, AS is granted to multihomed organisations which need to define their own routing policy. However,
- No. In AS you never specify IP-addresses, only the relations with other ASs. Route object is assigned to each IP-block with AS number. You get new IP-block of addresses and just specify in "origin" the number of you old AS.

- RIPE NCC does not work with simple users, only with Local Internet Registries (LIRs). Your can obtain IP-addresses directly from your provider or any other provider (true only about Provider Independent address space). Here is the list of LIRs http://www.ripe.net/ripencc/mem-services/general/indices/UA.html
- If you don't, the addresses that temporarily have been assigned for you will be considered free. Hence, they can be granted to some other applicant.
- There is no way you can do it.
In other words, if you still need AS, you will have to get your own address space. Below is the abstract from the upcoming FAQ on this issue:
------------------------------------------[ begin ]------------------------------------------
Mandatory requirements to get AS:
a) multihomed network. i.e. you should have channels to at least to providers with independent routing. b) you should have the address space, which you can announce "under this" AS. i.e., you should have at least one network/24, the "owner" (LIR) who would not mind if these networks switch to other AS (Note - LN have always minded that, still minds, and, as far as we can see, will mind if you do that. And not only LN...) If a) and b) requirements are not met (in fact these are not our requirements, it's just that we have to forward your application to RIPE, and if it doesn't meet these reqs, it won't be accepted), then the only local requirement will be the application itself... In English, in accordance with ripe-147, whereby you try to prove that you really need it... PS: : possible ways to "bypass" point b), or "how to get your own addresses": а) become a LIR, get a PA block from RIPE, and become forever independent (free at last) from upstream providers. Disadvantages associated with this method - for being LIR you'll need to pay a fee to RIPE from time to time. b)get PI-addresses b1) from "Sabana". As you might well know, in Ukraine for more or less symbolic price you can get 194.44/16... b2) from RIPE. It's free, but you have to submit very persuasive application explaining why you are not happy with PA-space.. ------------------------------------------[ end ]------------------------------------------
I want to stress that before you get AS, make sure your upstream providers support you. Because you might find yourself in a situation when you received both your address block and AS, but your upstream provider refuses to set up BGP communication with you. Top of the page
