I am working my way through the VZ phone channels, but if someone from Verizon who could help with T3 mapping in Manhattan could contact me off list, I would really appreciate it. I think I blew the poor phone techs mind when I asked him for help with that. :-) Thanks, Gerald

DoS and cable cuts take toll on entire country of Pakistan
by Sean Donelan 16 Apr '03

16 Apr '03

Guessing the motives of attackers is always difficult, but this probably has less to do with international politics and more with local politics and personal disputes. http://www.jang.com.pk/thenews/apr2003-daily/12-04-2003/business/b2.htm KARACHI: The Pakistan Telecommunication Company Limited has decided to isolate government websites from Pakistan Internet Exchange (PIE) to make internet browsers safe from Denial of Service attacks, which slow down the internet speed to a snail's pace, sources close to the company said on Friday. "The PTCL has decided to isolate these (government's) websites from PIE by providing a 2 megabyte IPLC link to National Telecommunications Corporation (NTC) and all sites are hosted at the server connected to this IPLC," sources added. "In this way, rest of Pakistan's internet could be safe from DoS attacks and only these 2 megabytes link would be effected," they added. Pakistani websites have been facing attacks by some hackers for over a month and thanks to DoS, the internet browsing is increasingly becoming a very trying job by the day. http://www.paktribune.com/news/index.php?id=22300 The Minister called up the presentation in the wake of strong reaction by the ISP community on the denial of service attacks on the Pakistan Internet Exchange for the last one month which also took its toll on the performance of entire internet infrastructure in the country. Earlier the company officials briefed the minister on the problems they had faced in the recent past on account of damage to their fiber optic cable as well as the incidents of denial of service attacks which slowed down the performance of all users.

Re: Dealing with ARIN.. my experiences & tips

Also Sprach Brian Johnson >OK. Let's all assume that Reform is necessary. >Please state, in detail, how you would reform ARIN and all of the >policy changes that you would instate (asside from giving you whatever >you want) to make ARIN "reformed" in the yes of it's membership. >I await, with baited breath, the answers form the Maha-Jeffy. :-) Alas...I agree with what some others have said. The answers aren't easy, and I don't have them all easily at hand. I think there are some steps that could be taken. Some comments off the top of my head... First and foremost...ARIN seems disconnected from the realities of running an ISP...particularly a smaller ISP. There needs to be more effort to understand the business needs of ISPs in general (again, particularly smaller ISPs) to understand *why* so many people (even those that do it on a regular basis and are "experts" in it) find dealing with ARIN to be such a PITA. They need to consider whether the policies that they have in place really and truly do accomplish the goals that they are supposed to accomplish. I think its pretty clear at this point that they don't. They need some common sense discussion about really how to accomplish the goals, the current policies clearly aren't doing it...even can be counter-productive wrt to the whole point of why ARIN was created (ie, more common sense policies would have resulted in me advertising half the number of routes in BGP than I am now...the goal of reducing routing table growth has most definitely not been accomplished in my case...and, as I've pointed out...I'm really *trying* to do the Right Thing...not all ISPs do). They need to "normalize" (for lack of a better word) their published policies...as well as "normalize" their actual policies with what's published. The feel that I get (this is a perception...not much hard evidence to back it up...but I'd be surprised if I'm alone in this) is that ARIN has put policies up on its web site, and then totally independantly, developed policies for operation...with the same basic set of goals in mind. The result being policies in real life that are similar, but not the same, as what's published. If there's a change in the real-life policy, that needs to be reflected on their website. As for some specific policy points that I think are bogus. Obviously, I feel the allocating for 3-months needs to be expanded...I'd say probably to a year would be reasonable. Basing it on past usage growth...ok...I don't have any inherent problems with that, but specific situations, such as a desire to renumber out of PA space, should be considered much more strongly than it is currently. Limiting SWIP to /29 or shorter prefixes doesn't seem to have much merit to me...I imagine a lot of ISPs wouldn't want to SWIP longer prefixes because of the administrative overhead (of which there certainly would be some)...our system allows us to do it pretty easily, so it wouldn't be a big deal here. And, as bdragon pointed out, circuit size (and I'll add network size) doesn't correlate precisely with ip address space consumption (ie, the idea that you can put a very large corporate network behind a single, or very small number of ip addresses). Certainly, large networks like that, should probably have their own records...even if only a single public IP address is in use. So, what guideline would I come up for this? As a discussion starting point, require anything shorter than /29 to be SWIP'ed, but leave longer up to the ISP...yes, not many ISPs would SWIP anything longer than /29, but we would, *particularly* if it made dealing with ARIN easier (which is should). Anyway...some starting points...I'm sure...with more thought and more experience dealing with ARIN, I could come up with some more suggestions...but I'll be the first to admit that I don't have all the answers. -- Jeff McAdams Email: jeffm(a)iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456

I haven't seen anyone in this thread advocate lying...though I don't follow all nanog posts, so I don't know if it may have happened in other threads...if so, I find that reprehensible. More than that I can't say. >> Again, we had greater than 80% utilization on *all* of our >> blocks...not just the most recently allocated one, and closer to 90% on most >> of them. The documentation that we gave to ARIN in support of our >> request showed this as well. >So you say. So...at this point, your defense of ARIN is to assume that *I'm* lying.

Silly me. >So, you did absolutely nothing. This is a common problem with many on >nanog. If I can't do something 100% my ay, I'ld rather do nothing. I did nothing because I was told by ARIN that I wasn't expected to re-number...that it wasn't a consideration in the allocation. I offered to renumber in the initial allocation because I was under the impression that it was required, not because we wanted to do it at that time. When they said it wasn't expected, or a consideration, no, we didn't renumber. Then we find out, much later, that it *is* a consideration, and that we're partially screwed because we didn't read their mind that it was a consideration when they were verbally telling us that it wasn't. >>Yeah, it would be silly of ARIN to actually abide by the documentation >>that they post on their website...so silly. >I've read their documentation. It sounds like they abided with their >policies to me. Depends on when you ask, apparently. (Actually, neither explanation I got from ARIN, either after the initial allocation, nor the one I got in the process of the most recent allocation, line up with what's on their website). >Oof, so even _you_ translate circuit size into eligibility for address >space? Actually...if you really want to get pedantic, we translate how much money a customer pays us into partial eligibility for address space. We still require justification, but if a customer doesn't have a certain size account, they won't get the address space even if they *are* justified for it. Again, we're going above and beyond what ARIN requires as far as address space requirements...despite your attempt to spin this into being my problem (why you're so emotionally invested in ARIN, I haven't a clue). >How stupid indeed, since circuit size has no bearing on need for >addresses (either in support or against). There is a correlation there...not strict, I'll acknowledge, but generally, larger circuits will end up using larger numbers of IP's. To deny that is as absurd as saying the correlation is strict, or to have a policy of certain size circuits automatically get certain sized allocations. Again, we try to do the Right Thing. I've turned down allocations from upstreams that weren't needed in an effort to prevent address space fragmentation and routing table polution, etc. >If I were ARIN I'ld definately look at your documentation with a close >eye. Again, your defense of ARIN seems to be accusing me of under-handed actions. >Well, good for you. However, if you think you can do this once and be >done, you are sorely misinformed. We haven't had to go back and redesign and renumber our network, because we learned from the first experience and have followed good allocation practices since then. I've gone back and audit'ed our network usage (informally) and it still falls within good allocation guidelines. So, no, I *don't* have to go back and do this more than once...as long as the allocations made, going forward, follow best practices, which we have. >In any event, it all comes down to: you had the opportunity to begin >readdressing. You failed to do so on anything but your own terms. Now >you (presumably) still have not readdressed and are still whining about >it. You just don't get it. As I mentioned earlier, we offered to re-number at the initial allocation because we thought it was necessary, but ARIN themselves told us it wasn't, that *IT WASN'T A CONSIDERATION*...you seem to keep skipping over this very important point...ARIN told us we didn't need to renumber. They lied to us, full stop. Had they been up-front and said that re-numbering would be a consideration at our next allocation, we would have (grudgingly) worked towards renumbering...again...since they didn't give us sufficient space to renumber, we would not have been able to do so completely, but we would have started the process. Let's be clear on this. Our decision not to start the renumbering process was informed by ARIN telling us it wasn't a consideration. I know I'm repeating myself here, but this is a critically important point that you have repeatedly ignored. >This thread has sapped too much of my time, and the brain cells of the >community. Hopefully you'll just go and renumber and quit your >bitching. No, as long as ARIN's policies and actions are ill-founded, they (and likely other relevant...at least tangentially) fora such as nanog will continue to hear about it...from me, and no doubt from others who have to tolerate this charade of trying to protect the public interest. ARIN has failed. -- Jeff McAdams Email: jeffm(a)iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456

Hello Nanogers, What is the best way to stop TCP DDoS, I'm not talking about UDP or ICMP, just TCP attacks, and not spoofed too. I see alot of attacks coming from rr.com and attbi.com beside other cable and DSL providers. Thanks, -J __________________________________________________ Do you Yahoo!? The New Yahoo!

Howdy Hank, Back when I was contributing to "Working Group C" (ICANN New gTLDs), through the clutter of trademark zealots (no new tlds ever) and anarchists (zillions now) the insight swept over me one like-verisign-to-compeat-verisign evening. Everyone wanting "in" was an amature, or one of the six new registrars, and a cut above amature, and no one had deep pockets, except courtesy of the dot gone bubble. So who could sweep this market, and bundle a domain name into their product... It hasn't happened. My crystal ball has a crack. Eric

ARIN meeting virtual attendance
by jlewis＠lewis.org 15 Apr '03

15 Apr '03

As is pretty clear from recent threads, there are ARIN members who, for whatever reasons, don't or can't attend the public meetings, but would like to have some input into ARIN's policies as well as voice their concerns over the current state of ARIN <-> member interaction. Since we're a relatively high-tech group, has anyone ever looked into what it takes to setup virtual attendance? i.e. I'm guessing a good number of network operators have either participated DoveBid's auctions (getting the network and office goodies at auction from your failed telecom competitors) or know people who have. I've personally been to these both in person and virtually. In virtual mode, you get to listen in on the auction and speak when necessary (i.e. to bid). With a bit of hardware, I bet this could even be done with VOIP, removing the need for anyone (ARIN or the members) to pay for the long distance calls for virtual attenders. I don't know what hardware/software is involved in this (i.e. what DoveBid uses), but IIRC, ARIN does have several million in the bank. What better way to spend our money than to facilitate member participation? I think this would be a great way to get more member participation at the meetings...and (for personal reasons) it's the only way I can see myself getting to a meeting in the near future. ---------------------------------------------------------------------- Jon Lewis *jlewis(a)lewis.org*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

I just don't see a problem here. Ah, but when you buy address space, are you going to be happy about giving it back when you change providers? Will the provider give you a fair price on selling it back? Do you think sales departments won't insist you buy their address space when you connect? And if you can keep it, it makes the routing table more and more interesting. > > Second, groups that make the Internet go aren't necessarily the ones who > > can afford the address space. > > If they can't afford the address space, there's a very good chance it's > because they are inefficient and they should be done away with.

Much of the research and coordination of the Internet is done by research groups and universities.

Why not make the Internet now "The Internet, Brought To You By Company X?" You need Company X's address space, so you have to provide Company X's services on Company X's operating system?
