Only packets from the incorrect world will be hit by these filters. As a matter of network policy, I do not wish to speak to incorrect hosts, whatever their intentions. If being unable to connect to MSRL hosts causes people to fix their incorrect configurations, I am pleased. If it causes them to be upset, I am indifferent. The smoothly running Internet is the set of standards-compliant hosts. We must guard against incorrectness with a steady, ruthless, automated hand. -- Shields.

Geeze paul. People have been dealing with impersonation for eternity. Just because you get impersonated by a few people you want to put the entire list under marshall law? I hope you dont ever run a country. Let YOUR actions speak louder than impersonated words ("Paul would NEVER say that...") Dont you have some bugs to fix in bind or something? Instead of whining about other people's actions, bring yours up to par first.

The state of NANOG
by Richard A. Steenbergen 14 Jul '00

<rant> At the risk of generating more useless traffic that noone cares about, could please try and show a little more maturity on NANOG? The occational diversion is nice, but noone wants to sort through spoof mails from "Vaul Pixie" or "Bandy Rush" every day to fill someone's #nanog or #cisco vanity fix. Noone wants to hear about the personal tales and tribulations of .god and the little roach that could. Noone wants to hear the latest rant about the moral righteousness of someone's spam or RFC1918 filters. NANOG is NOT the replacement for whois and a phone book, if you can't get ahold of someone from some of these company's you havn't tried hard enough (for example, if you're looking for an abovenet engineer, why don't you try mailing noc(a)above.net, I'm sure you'll find one), and if you want to post messages and then ignore your private responses you don't need to tell us about it. And for the love of god, if you can't read a book, try asking your Alcatel coworkers about your beginner questions before you make a useless post to NANOG. If we wanted to read these things we'd subscribe to inet-access. Please, no reply's to this (cc'd 4 times) with "I agree", no ensueing debate on making NANOG moderated, no spoofed CERT advisories about the insecurities of "Vaul Pixie", just realize that its time to knock it off, and maybe stop to think before you open your mail composer. </rant> -- Richard A Steenbergen <ras(a)e-gerbil.net> http://www.e-gerbil.net/humble PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)

Agreed, there is far too much impersonation happening on this list, I am sure that Bandy Rush would agree with me as well. To have malicious people abuse our good names is just unacceptable.

It is easy to argue that using interface 1918 addresses and PMTUD are incompatible with connecting to the Internet, for PMTUD requires sending an ICMP message with the source address of the interface, and using 1918 space on the Internet is not allowed. RFC 1918 section 3: "In order to use private address space, an enterprise needs to determine which hosts do not need to have network layer connectivity outside the enterprise in the foreseeable future and thus could be classified as private. Such hosts will use the private address space defined above. [...] However, they cannot have IP connectivity to any host outside of the enterprise." "Indirect references to such addresses should be contained within the enterprise. Prominent examples of such references are DNS Resource Records and other information referring to internal private addresses. In particular, Internet service providers should take measures to prevent such leakage." -- Shields.

It's purely technical -- it outlines the purely-technical reasons why the DNS has to have one root if we're to have effective communication on the net. As for technical papers -- if nothing else, there are the workshops the IAB sponsors; the reports of those workshops are also on the IAB Web page. The report on the Network Layer workshop is about to be released; there are also forthcoming RFCs on QoS and security. > >I submit that the IAB isn't doing its job and until they do, they >should refrain from wasting their resources in the policy arena. > I suspect that the entire IAB wants to spend less time on politics -- I know I'd rather stick to the technical stuff.
