Fwd: ARIN ORG ID for non-ARIN region company
by George Toma 14 Oct '22

14 Oct '22

This was the reply I got from ARIN to my inquiry: Hello George Absolutely out of region organizations can establish an Organization ID and record with ARIN. They should be asked if it is for reallocation purposes and once that is answered affirmatively then ARIN will create the record. At this time ARIN does require a $50 dollar fee as well as the organization must sign an RSA. Please reach out if you or anyone else has other questions. Thanks, John S.

ARIN ORG ID for non-ARIN region company
by George Toma 13 Oct '22

13 Oct '22

Hello, Does anybody know if it possible to create ARIN ORG ID for non-ARIN region company? We are LACNIC region based. In LACNIC as well as RIPE regions the RIRs allow creation of ORG IDs for non-region companies for purposes of IP reallocations, etc. (e.g. IPv4 lease, etc.). I have gone to ARIN ORG ID registration page but it says only ARIN region companies can register in ARIN. We need this for purposes of IPv4 reallocation of our IPv4 leased subnets so also the contact handles are reallocated to us. ARIN asks me to pay for creation of ORG ID, but I would lose the payment if the request is denied. We do not plan to request any resources, no ASN or IP resources will be requested through that ORG ID, it's only to allow for full IPv4 reallocation (including contact handles). Thank you for any input. Regards, George

Re: any dangers of filtering every /24 on full internet table to preserve FIB space ?
by Jakob Heitz (jheitz) 13 Oct '22

13 Oct '22

Here is a reason you might want to keep that /24. Suppose you are a small ISP and I am your customer. I also have another larger provider. That larger provider is also your provider. I own a /21 and advertise it to my larger provider. You get that /21 from my larger provider. I advertise a /24 subset of the /21 to you. If you ignore my /24, then traffic for it goes to the larger provider and I pay him for the traffic, not you. Regards, Jakob.

CLEC lawfirm recommendations?
by Tim Utschig 12 Oct '22

12 Oct '22

Hello NANOG'ers, I hope this isn't too far off-topic: I'm wondering, does anyone have any recommendations for a lawfirm that will help a newbie through the process of becoming a CLEC? I understand that it can take years, and am prepared for that. Specifically in San Jose, California. I'm trying to determine (by trial and error) the theoretical minimum cost of running a tiny neighborhood FTTH + very-short-range fixed-point wireless ISP for residences that don't have fiber for no good reason at all. https://mplink.llc/img/mplink-v0.1-pencil.jpg Have gear, some funds, conflict-of-interest exception, and a smidge of clue. Even have the first run of fiber already pulled (via quickly-cancelled AT&T Dedicated Internet). Just need https://clec.att.com/ access and somewhere to put my gear on the other end of the line. I think. Cheers. -- Tim Utschig <tim(a)tetro.net> 408-644-3861 (mobile)

Any experiences using SIIT-DC in an IXP setting ?
by Carlos Martinez-Cagnazzo 10 Oct '22

10 Oct '22

Hi all, I'm looking at a use case for stateless 6-4 mappings in the context of an IXP. The problem we are looking to solve is allowing IXP members who have no IPv4 of their own and in most cases they have a /26 or /27 issued by their transit provider and rely on CGN to provide service to their customers. They do have their own AS numbers and IPv6 prefixes though. Any comments are appreciated. PM is fine too. Thanks! /Carlos

FCC chairwoman: Fines alone aren't enough (Robocalls)
by Sean Donelan 10 Oct '22

10 Oct '22

'Fines alone aren't enough:' FCC threatens to blacklist voice providers for flouting robocall rules https://www.cyberscoop.com/fcc-robocall-fine-database-removal/ [...] “This is a new era. If a provider doesn’t meet its obligations under the law, it now faces expulsion from America’s phone networks. Fines alone aren’t enough,” FCC chairwoman Jessica Rosenworcel said in a statement accompanying the announcement. “Providers that don’t follow our rules and make it easy to scam consumers will now face swift consequences.” It’s the first such enforcement action by the agency to reduce the growing problem of robocalls since call ID verification protocols known as “STIR/SHAKEN” went fully into effect this summer.
