Hi NANOG, We are running short of IPv4 addresses. We are a small ISP and longer prefixes are okay with us (even /24s). Please contact me off-list. (Proper ROA coverage is a must). Thanks. Best Regards, Suriya

Besides ROAs, it is also prudent to ask for IRR coverage as well. That may or may not come right away from ROAs depending on the type of resource (legacy x non-legacy) and RIR involved. Rubens On Tue, May 6, 2025 at 3:36 PM Suriya Kamon via NANOG <nanog@lists.nanog.org> wrote:

I have had excellent luck personally and professionally with both ipv4.global (for purchases) and ipxo.com (for leases). If you have an ASN already, you can grab a /24 from there for about $120/mo now, cheaper with terms. The following represents solely my own opinion without judgement and nothing more: personally recommend you google the names of people who have replied to you already in this thread along with the phrase “afrinic” and decide if that’s the kind of place you want to tie your business to.

I wholeheartedly agree with and support doing research about who you choose to go into business with... There are some that are good to do business with and do support real-time allocation of resources (IPXO) and some who are not the best to do business with due to their reputation (...).

Hello Suriya, IPXO can definitely help you out. We have /24- /16 subnets available from all five RIRs, with full ROA support. The platform is fully automated, so all you need to do is register at www.ipxo.com and select the subnets that work for you. Alternatively, you can email me at paulius[at]ipxo[dot]com. Regards, Paulius

Hi Yes, I has long been a strong advocate for networks having greater control and ownership over their IP addresses—a position that not everyone in the status quo agrees with. That said, NANOG remains a transparent and open community, and I believe most of us here prefer to compete on the quality of service, not politics. We also proud to be a long-term sponsor of NANOG and to continue supporting the community. On Tue, 6 May 2025 at 20:26, Paulius Judickas via NANOG < nanog@lists.nanog.org> wrote:

Hi, Suriya: 0) I am glad that you requested off-list follow-ups, because what I am going to share is quite controversial. With a general distribution list, a discussion can easily be pulled off the track by personal / emotional opinions or business interests, as you might have noticed on the NANOG Forum in the past. 1) I would recommend you to consider replacing 100.64/10 netblock with 240/4 netblock for the CG-NAT configuration. This will reduce your need for IPv4 addresses by 64 fold, thus mitigating the IPv4 address shortage that you are facing. 2) Although there have been (and still are) various attempts to make use of the 240/4 netblock, none has approached it in a universal sense as our proposal, called EzIP (phonetic for Easy IPv4). Others are either piecemeal solutions for special cases or limited scope applications. They will fragment the Internet and lead to chaos. Characterized by Vint Cerf as an "Overlay Network", EzIP scheme forms a new layer of communication infrastructure that is independent of, yet in arm's-length with the current Internet core. So that, EzIP can retain the desired properties of the existing Internet, while shaking off the handicaps. The former maintains the operation characteristics as CG-NAT to avoid perturbing users, while the latter enables the Internet revamping into a new era. This far-reaching implication is possible because EzIP resolves the most fundamental issue of user identification resources. From such, many constraints are either relaxed or simply removed. 3) For a general introduction, please have a look at the below pair of documents. https://avinta.com/gallery/DeterministicInternetIntro-US.pdf https://avinta.com/gallery/DeterministicInternet-SPKR.pdf 4) Since this topic touches many aspects of the Internet and we are not an operatorbut just a system analyst, we likely have not covered many aspects that hands-on parties like you are familiar with. Please browse through our website to see other background information which may be relevant, then let us know your concerns. So that we can evaluate them for you.

Suriya- Just so it is clear, the technology that Abraham is referencing ( EZIP ) is ONLY a proposal that has been made. It has not been accepted by any standards body. It is not implemented or supported by any major router vendor. It will not work for you. On Tue, May 6, 2025 at 11:41 AM Abraham Y. Chen via NANOG < nanog@lists.nanog.org> wrote:
