Resent: Allocating a LIR an IP block per use
Hi all, We would like to request another IP block from RIPE, regardless of our current allocation (which we use for our day-to-day assignments to customers), in order to assign from this block only to customers using BGP. I would not want to assign BGP customers from our regular blocks, as it would create a need to subnet the BGP advertisements on these blocks. We would like to have a block pre-intended for such fragmentation. However, as far as I recall RIPE's procedure, one can request another IP allocation only after a certain percentage (50% AFAIR) of his allocation has been assigned. So - am I the only person thinking this is the correct way to do that? Is it possible to request a block for such usage, regardless of the current allocation's usage?

Bonjour, No you'r not the only one in this case, we have customers with AS number and we are ambarrassed they do not announce there IP because it's icluded in our total agregate IP space, we will be very happy to obtain 2 to 4 ( \23 or \22) for each of them according to there needs, maybe RIPE should help us to find a solution about this situation.

Many small ISPs, sooner or later, want to become multi-homed and they meet with that problem. All of them usually want to run BGP even if they are assigned a small portion of address space. On the other hand, huge ISPs (e.g. Sprint) use to filter BGP announcements for prefix longer than a certain value (usually /19 or /20). Therefore, such multi-homed customers can have serious connectivity problems. The best approach for small BGP customers is to use NAT. See the slides on that at http://www.ietf.org/proceedings/98dec/slides/nat-multihome-98dec/.

Which is a (serious?) waste of address space, since it requires at least two times the same assignment. On the other hand, it saves one ASN and one potential new buggy AS is kept away from the BGP4, so it probably evens out. On the other hand, NAT _is_ a _kludge_ for multihoming. But the ISP who really thinks his customer needs his own AS and is capable of setting it up (or having it setup for them) is probably also able to convince RIPE NCC they need PI...

Agree with that part, though everything depends on NAT implementation (the possibility of address reusage) and the size of the customer network. And yes - it doesn't provide all the benefits that BGP does. On the other hand, convincing RIPE NCC to provide PI addresses might even be much easier than convincing Sprint to remove their filters for such customer networks. The main reason Sprint uses to filter BGP announcments on /19 is the size of the routing table and a large amount of updates for small networks.

Yuval, You could apply for PI (Provider Independant) address space. But you would still need to fill out a RIPE-141 outlining how you intend to use the address space. The other problem with PI space, is that a lot of the backbones don't like routing it unless you have a fairly large aggregate. The issues are raised in http://www.ripe.net/docs/ripe-127.html Joolsie Yuval Shchory wrote:
