I was asking about almost the opposite. Actual scenario is this: Load balancing WWW and IRC servers. I believe this use of load-balanced DNS would be a fairly typical use. I want all users from IP space allocated to ARIN to go to my US web and IRC servers. I want all other users to go to my EU based servers. I want to maintain two primary servers in each continent as hubs across which all traffic flows, and data is sync'd. As someone clearly pointed out to me, people have taken IP space from these regions and ported it to other places in the world. While this may be true, I believe it's use is small enough that I don't have to worry about it too much. On the other hand what you point out would be a very important effect for this. Potentially a good way to obfuscate your hostnames to either a small select group, or to the whole world.
Re: Cisco blunders with insecure web page

When one Makes it sound like Cisco were publishing the private details, so they forgot an SSL cert. big deal, its not like snooping unencrypted details on ISP backbones is a reality anyway! irate silicon.com reader called the Cisco helpdesk, he was informed that the company was aware of the problem because several other users had complained. In fact people have much more access to the information when its posted in the mail.. looks like Silicon have an axe to grind Steve Helpdesk staff recommended that users enter fake details on the web and forward the real information in the post, a course of action our reader regarded as an extreme waste of time.

RE: The Significance of Five 9's Reliability (fwd)
If you include leap years in the calculation, ie, 525,960 min/yr then yes, availability of 99.999 comes out to 5 min of downtime. The techniques the telcos follow to achieve 5 9s are amusing but here's a few comments. If I had the level of availability of my home phone on my frame/atm networks, I could probably get my handicap down to around 2 or 3. As it is, I have alot of trouble breaking 80. (golf reference) Another thing, some of the comments in this thread make me understand why the availability of the voice network infrastructure is so much superior to that of the data side of things. For one, alot of network engineers that I know don't know the ins and outs of how to calculate availability. This is troubling since it means that even if they accidently design a highly available network, they are left guessing and not predicting how available it will actually be. Every person who calls himself/herself a network *engineer* should be familiar with calculating 3 sorts of availability: 1) Device availability calculated by combining the availabilities of all the significant components of that device 2) The availability of serial vs parallel systems/designs 3) End to End availability calculated by combining the availabilities of groups of devices which function together to achieve a common purpose Some networks do not merit such analysis but you can bet that the 911 emergency services network does and should have this and much more detailed analysis. Another rant if I may. An engineer who can't calculate availability also can't calculate ROI. The cost of employing a certain network design is largely a factor of how available it's going to be. If you build a $2mil network where hour long outages cost the business $400k, maybe you should have built a $4mil networkespecially if you know that you can count on 20 hours of outages during normal business hours If you've read this far, you may be interested in a book tip on High Availability Networks: Cisco Press: High Availability Network Fundamentals by Chris Oggerino.

I use a 'match-clients any' statement in the last view. Everything falls

Internal and external have their own views of sensitive zones, but they

Generally something doesn't get Slashdotted unless it is fully of poorly written dynamic code which should never have been put in production in the first place, such as PHP doing 20 mysql queries per page view or something else equally stupid and linux kiddie. A BOFH quote generator, on the other hand, is very very simple. It boggles the mind to imagine a server so weak or code so bad that it couldn't handle a couple hundred connections from NANOG readers. If that is the case, I would strongly suggest you reevaluate the language or method in which it was written. I beg your pardon? Where did you get the idea that I wrote or hosted it? I was assuming it'd been Slashdotted because it was working fine before I posted the link, then stopped working shortly afterwards. It's also entirely possible the somebody at the site got annoyed at all the requests put a DENY ALL on it. -- W . | ,. w , Some people are alive only because \|/ \|/ it is illegal to kill them.Perna condita delenda est ---^^---

RE: The Myth of Five 9's Reliability (fwd)
[stuff missing] When applied randomly to the Internet, I suppose that means if you can dial into a RAS and establish a PPP/IPCP session, but the RAS' connection to the Internet is down, then the service is up :-) [stuff missing] I seem to remember a large internet provider's service contract reading something to the effect of. Your server is considered down if customer router cannot pass packets [or ping] with service provider's immediate upstream router. This is a functional description of the above for dedicated lines as customer aggregation routers never talked to the internet, so if there was a problem at a transit router you weren't getting anywhere. A modern contract I saw recently defined up for colocation purposes as the customer's assigned gigabit port is available. Though available was not a defined term, one could not easily apply that to a ports' willingness to pass packets. One could say a congested port was not available though I guess. Deepak Jain AiNET

The ratio of useful traffic to spam/attacks from APNIC space is already so low as to be nearly non-existent. A little active help from a governmental body couldn't make it much worse than it already is. --- Also a good point. :) I think the media makes a big deal about gov't sponsored cybermischief because I think the implication is that they'd do it better than a few kiddies. While a gov't sponsored group may use information illegally gotten better, I have never seen evidence that they are more effective or more sinister in their successes. YMMV, Deepak Jain AiNET

Deepak Jain AiNET No harder than it is to believe that the US Govt would actively fund [cyber]terrorism... -- Yours, J.A. Terranson [EMAIL PROTECTED] If Governments really want us to behave like civilized human beings, they should give serious consideration towards setting a better example: Ruling by force, rather than consensus; the unrestrained application of unjust laws (which the victim-populations were never allowed input on in the first place); the State policy of justice only for the rich and elected; the intentional abuse and occassionally destruction of entire populations merely to distract an already apathetic and numb electorate...

RE: CIA Warns of Chinese Plans for Cyber-Attacks on U.S.
You know, we all my be the first to see and understand that such a attack is in progress...attacks against critical targets can come from anywhere with distributed computing. Even IF we detected it happening, the question is, who would you tell, and more importantly, do you trust YOUR government with that information? With whats gone on to neutralize the Constitution since 9.11, its hard to say just who IS the enemy. I know the whole process of turning the US into a police-state is un-nerving to say the least. But I digress That whole article thats in the LA times is a rehash of the article that was on C4I.org back when the US spy plane was held in China.
