Certainly.
You only benefit from having your own AS-Number if you want to exchange routing information with two or more other networks via bgp (and have at least a /24 ipv4 or a /48 ipv6 - as those are generally the smallest size networks you will see in "global" routing).
Other than for routing purposes, the AS-Number has no direct benefits. Its basically just a unique identifier.
In terms of the AS-Number i makes no difference if you have ipv4 or ipv6 resources.
The Use-Cases are simple:
Have a technical need (ie: connect to more than one network(ie:isp), have some ip-resources (assigned to you) that you want to show up in the global routing table and want to exchange said routing information with BGP).
Lets talk who to obtain an AS-Number from:
The cost depends on the route you take and who you deal with. The Fees for becoming a Member of a RIR are typically published on their website. This is typically more expensive than just getting resources thru a LIR in most cases.
So what is the process like?
This depends on the RIR, but generally all of them will require your network to be "multi-homed", meaning you need to connect to two other networks and will want to exchange route information with BGP.
In order to process the request:
Regarding Knowledge to use an AS-Number:
The AS-Number thing is really more just there so you can be "multi homed" with bgp..." and define your own routing policy if you connect to multiple networks...
Knowledge Required:
There are quire a few tutorials online on how to get this done. Regarding your "ccna?" question: No, BGP is outside of the scope of the CCNA curriculum, as it only contains rip and ospf for dynamic routing. For neither of those you will need an AS-Number.
I hope this helps, let me know if you have any further questions.
first of all thank you both for answering!
I'd say i have about max 100$ to burn (lol)
/48 ipv6 is like 65k adresses, for 50€/y recurring? this does not make sense to me, people offer it way cheaper with VPS' is my math wrong?
yeah i'd like to have an ASN and later a IP block which apperantly i can't OWN but i have to lease?
we have like, infinite v6 adresses so ehhh
soon is BF so yeah...
The answer to this is dictated by policy. The billing just reflects it. So lets break down this one. Anything below is just reflective of how Ripe Deals with it - Other RIR's may do it differently.
Provider Independent (PI): Provider Independent (PI) address space is assigned to End-Users for the purpose of infrastructure. RIPE does not permit these end users to rent out or distribute the IP address space to third parties.
Provider-aggregatable (PA): Provider-aggregatable (PA) address space is assigned to LIRs who may assign or sub-allocate portions of this address space to customers.
So when you see PI for 50 per year, that is "at or below cost", as ripe bills every sponsored PI resource to the LIR at 50 / year. This is before you apply any payment gatway fees, administrative work or Tax...
When you take a look at the Plans for PA listed at MyRotoPW you will see something like "/48 up to /40 IPv6 Assignment". This basically means we "reserve" a /40 per client that has that plan. However due to the policy, we generally make smaller assignments out of that, one /48 at a time ("one for each site"). Unless the end-user can demonstrate a technical need for larger assignments at any given time...
So in short the "PA" is issued to you at for the duration of your contract with the LIR. You cannot "transfer" it to another LIR, or to yourself if you at some point become a LIR yourself. However in terms of how it can be used.. You can use those resources for yourself and even for some clients of yours. With PA it "usage rights" is granted to you - however you may only use it for yourself.... However you can find a different "sponsoring LIR" at any point.
"Sponsoring" means that LIR acts as your tether to the ripencc and is your point of contact,.....
The whole "its so big, just give us $amount of space" really does not work in relation to the policy. See https://www.ripe.net/publications/docs/ripe-738 and https://www.ripe.net/publications/docs/ripe-690
The real question you got to ask yourself in the long term is this: What happens when the RIR audits your LIR and discovers non complience in terms of policy and space allocations.....
If you have any other LIR Questions, le me know.

Best one I read so far on the topic
For clarity.
Thank you for fixing my typing error.
