Apparently not. We did, that's why we use DNS. As long as we practice collision avoidance, we won't have any problems. However, those that intentionally collide must be made to pay for it. ICANN, by flat-out ignoring the existing RSCs, basically told the rest of the world that it is okay for everyone else to ignore each other too. Had ICANN even tried to include the existing RSCs, we would now have new, non-colliding, TLDs.(IMHO) Personally, from my vantage point, the Internet co-opetition model is collapsing. Co-operation is a tit-for-tat game and no one is going to play without some "quid pro quo". ICANN wants it all one-way and that isn't going to happen anytime soon. In fact, such policy stance encourages polarization and fragmentation of the market/community. This is what gave rise to the opportunity that new.net is trying to exploit. Inclusive co-opetition would not have prevented the rise of new.net, but it would have given them strong encouragement to NOT have colliding TLDs. BTW: Co-opetition ::= cooperative competetion.(coined elsewhere)

That may be a little extreme ... I generally get good support from all of my upstreams. However, there's a certain amount of static to be expected when you start raising inter-provider issues, especially when all the latency seems be caused by the provider you aren't a customer of. -travis On Tue, 13 Mar 2001, Tom Thomas wrote: > Bad attitudes to a customer are a clear indication you should take your > money elsewhere. > > Personally I like NetRail, they are courteous and responsive. > > > > -----Original Message----- > From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of > Travis Pugh > Sent: Tuesday, March 13, 2001 1:13 PM > To: nanog(a)merit.edu > Subject: UUNet / ATT peering meltdown? > > > > > Not to open up any potential disputes, but has anyone heard what is going > on between UUNet and AT&T on the east coast?

Prefix length filtering at the ISP-ISP edge
by Alexandre.Gibouin＠sita.int 13 Mar '01

13 Mar '01

Nothing new in this mail but I need some clarification ... - To my understanding, the common practice is, at least, to accept any address block larger or equal to /19 and to filter any block smaller than /24 (except eventually at the customer-ISP edge). ARIN and RIPE have changed for a while their minimum allocation size to /20 so I guess there is no risk of routing blackhole with /20 blocks, right? - What about PI-blocks between 21 and 24 bits? If a end-user network annouces such an address block, what is the risk of routing blackholes throughout the Internet? - Each ISP seems to apply its own filtering policy. Nevertheless, what are the most common filtering practices for the ISP-ISP edge? - Is it common to have different filtering policies depending on the address ranges? I will be grateful for any link to official or non-official documentation. Thanks for your help Alex

Looking Glass Code
by Don Simpson 13 Mar '01

13 Mar '01

I have been thinking about putting together a looking glass site on my network and have looked at Ed Kern's (DIGEX) html and perl script but do not want to enable rsh (anywhere) and do not want to reinvent the wheel if not necessary. Has anyone seen an updated script written to use other access means like telnet or ssh to exchange CLI/commands and results with an IOS router? ---------------------------------------------- Don Simpson ----------------------------------------------
