RE: IPV4 as a Commodity for Profit
by John Lee 29 Feb '08

29 Feb '08

Rod, I used the term "clueless" in that message because of the number of times this concept has been discussed before primarily by business types who do not understand how the "Internet" works. In the large and small businesses that I have been in and with the ISPs and service providers (SP) I have worked for, addresses have usually been allocated sub-optimally. The free space is usually scattered across the allocation and the prefix for it is to small to announce. If this is a medium to large size company the ISP or interconnect provider would aggregate all of the routes for their own annoucements to tier 1 and 2 providers. IMHO ISPs and SPs could share space among their customers since they can then aggregate to an acceptable level to announce to the Internet but I do not see this as a "market". I not only embrace market mechanism, but with some of my colleagues on this list, was developing a bandwidth trading market while at EBS. IMHO the amount of technical effort to extract these final v4 addresses is more work and cost then transitioning to v6. All major router and switch vendors have been v6 capable / ready for two years and most tier 1 carriers support v6 traffic today.

ARIN (and other RIRs) and the rules of use of IP address were specifically setup to allow global communications around the world with a large number of entities on an equal basis. IPv4would be afixedsize pool of acommodity and from my training at Enron in trading (they were the largest in the world by number and volume of trades) it only works under several rules. You have a group of suppliers and consumers, you have a measurable commodity and a standard way of measuring it, you have a standard set of commodities, you can assign a value to the commodity etc. If I grow corn or drill for "Texas Light Crude" there standards in place so that if you drill in the Middle east, China or Russia you produce the same "Texas Light Crude" to trade. Trading of IP address does violate ARIN rules as ARIN has explained to me since to "Trade" something is to have title or ownership of that item and that ownership belongs to the cognizant RIR not to a company or person. Regards John PS: The RIRs are community driven and so if the community wants to become a market place, they can petition ARIN have a vote and change if the majority of the community wants to. ---------------- From: Rod Beck [mailto:Rod.Beck@hiberniaatlantic.com] Sent: Mon 2/18/2008 12:05 PM To: John Lee; Raymond Macharia; NANOG list Subject: RE: IPV4 as a Commodity for Profit Hi John, I think that comment is way out of line. In fact, I met at LINX one of authors of a trading proposal. They are smart, well educated individuals. Markets have proven to be excellent mechanisms for allocating resources fairness is a distinct issue) and might be the medication required given the apparent hoarding of IP addresses. Nor is the trading of IP addresses inconsistent with ARIN ownership. Regards, Roderick S.

Albert Einstein. -----Original Message----- From: owner-nanog(a)merit.edu on behalf of John Lee Sent: Mon 2/18/2008 4:45 PM To: Raymond Macharia; NANOG list Subject: RE: IPV4 as a Commodity for Profit Distribution: This "idea" comes from clueless individuals who want to know "who owns the Internet"? When I worked at Enron Broadband Services "the crooked E", management wanted to buy PSInet so that "we" could developed a trading desk for IP address blocks. We informed management that neither EBS or PSInet owned their IP addresses but rented them from ARIN. And when the organization indicates that IP addresses are no longer needed, they can be returned to ARIN or ARIN can come and get them from the organization per ARIN AUP and other policies that users signed when making a request to ARIN. (Review a court case several years ago, about a company going into bankruptcy, I believe, claiming that "their" IP addresses were part of the assets of the company...) Now for those who could not follow the last paragraph, the analogy is when you were young and renting your apartment or house and you wanted to make money selling one of the rooms of your rented apartment or house. So anyone with spare /16 or larger send the blocks back to ARIN so they can be good stewards of the diminishing resource.

Hi, I was wondering if anyone knew of server hotel locations in Sweden or Greece. More generally, if there is a good resource for me to look this up myself next time.

Qwest desires mesh to reduce unused standby capacity
by Frank Bulk - iNAME 28 Feb '08

28 Feb '08

I found this section of a Telephony Online article interesting: Though networking trends point toward an evolution to mesh networks, nationwide carrier networks currently lack the physical diversity that would help carriers realize the benefits of true mesh networking, Poll said. Qwest, for example, has about three or four cross-country arteries that correspond to railway rights of way. Replacing that with a more mesh-like architecture would increase the complexity of operating the network. For one thing, it would require more uniformity in the capacities of various network routes. "You'd have to have units of 10 Gb/s traffic between all points on the network before this becomes economically viable," Poll said. "When you place IP capacity, you have to place a lot of standby capacity to carry traffic along different paths. If we could get greater physical diversity in place, we could greatly diminish the amount of standby capacity we have to take." In order to realize the benefits of mesh networking, Poll said, carriers will need to cooperate with each other more than they currently do, using fiber swaps to increase the geographic diversity of network paths. http://telephonyonline.com/access/news/ofc-qwest-optical-0226/ To keep this OT as much as possible, my question is if a mesh-configuration of backup routes (where one link could provide 'protection' for many) would be considered a sufficient replacement for SONET rings, or if the Qwest CTO is really trying to get out of providing sub 50-msec protected loops and encouraging L3 and above protection schemes, so that they can even further over-subscribe their network.

RE: Yahoo! Mail/Sys Admin
by Justin Wilson 28 Feb '08

Hello Everyone, It's been a while since I posted on this topic, and unfortunately I'm still having trouble with Yahoo deferrals. The links that were provided in this post worked, but after the forms were received by what I *think* is a human I still got a canned reply. I've tried replying with specific details about our problem, but is either answered with another generic reply or not at all. We are running Imall, and each domain has it's own IP address. Queue Timer and Tries before returning to sender are set to 30 minutes / 5 attempts. According to yahoo they do want you to attempt to resend if you get a 421 error. SPF is also set on a per-domain basis. I'm not sure what else to try. Does anyone have a better understanding of how Yahoo greylisting works? Thanks in advance! Justin Wilson

I seem to have lost connectivity to AS 2828/XO communications. I can't get through to anyone on the BGP team at XO either. Anyone else experiencing this? Reply just to me, don't need to hold up thread time. Zaid
