Well that's for end users. The company in question seems to be a Telecom operator. The RIPE model is a very strange and confusing one, where ISPs basically become LIRs and they themselves assign ASNs and IPs, and there are 23000 LIRs in ARIN. Basically any ISP , webhosting company, datacenter or even a trading company can become a LIR. It's a very strange model which had just cost me 15 minutes of my time to just dig into and get some basic understanding of it. I would not put my hand in the fire that the OP is a LIR or not, but they are an ISP so I would assume they are LIR and as such can reassign the IPs,a nd if they are not LIR they can become one. Anyway many of IP renting companies such as IPXO are RIPE-based, and those who are ARIN or APNIC based also have subnets from RIPE region. If RIPE was against subletting, the whole market would not exist with RIPE subnets. Regards George On Tue, Mar 21, 2023 at 2:17 PM <ayang () august tw> wrote:

Autonomous System (AS)An Autonomous System (AS) is a connected group of one or more IP prefixes run by one or more network operators under a single and clearly defined routing policy. 2.3.1. Autonomous System Number (ASN) An Autonomous System Number (ASN) is a unique two- or four-byte number associated with an AS. The ASN is used as an identifier to allow the AS to exchange dynamic routing information with other Autonomous Systems." Nothing prohibiting ASN sharing and 2.3 specifically states "run by one or more network operators... single routing policy" Regards George On Tue, Mar 21, 2023 at 8:00 AM <nanog-request () nanog org> wrote:Message: 19 Date: Mon, 20 Mar 2023 16:24:09 -0400 From: ayang () august tw To: Collider <large.hadron.collider () gmx com> Cc: nanog () nanog org Subject: Re: Spamhaus flags any IP announced by our ASN as a criminal network Message-ID: <5b7ed1b1fbff65dfc63d188c2e1f95af () august tw> Content-Type: text/plain; charset=UTF-8; format=flowed Several Huize ASNs, e.g. AS47158 and AS141011, were revoked due to RIR policy violations, which include prohibited sharing of ASNs with third parties, IP hijacking, and malicious path prepending. Given this history, it is not surprising that Spamhaus would blacklist IP addresses associated with their ASN. In my opinion, such action is well-justified. Best regards, August Yang
