ok,
let's suppose that usually provides the most appropriate environment for placing the dns servers and their co-infrastructure. taking it only technically, providing the connectivity for the ixp is a detail (to announce or not to announce). maybe the ixp could allocate a 'stub' subnet - separate from the transit subnet - and provide a voluntary mlpa to all the hosted isps. this would not break the isp policies on announcing the transit ixp subnet. all these are details. i see a space for another topic in this thread - updating the dns infrastrucure a bit. to be more specific: - would the ixp-located tld dns servers server only a small set of tld's each? if so, would it be region-based or agreement-based? - would it be worth the effort starting a project similar to irr that would serve as a common source for dns configurations? it'd be nice to hear your oppinions -- Tomas Daniska systems engineer Tronet Computer Networks Plynarenska 5, 829 75 Bratislava, Slovakia tel: +421 2 58224111, fax: +421 2 58224199 A transistor protected by a fast-acting fuse will protect the fuse by blowing first. > -----Original Message----- > From: Arnold Nipper [mailto:[EMAIL PROTECTED]] > Sent: 6. júna 2002 16:29 > To: Daniska Tomas > Cc: Nipper, Arnold; [EMAIL PROTECTED] > Subject: Re: Re: KPNQwest ns.eu.net server. > > > On Thu, Jun 06, 2002 at 04:13:08PM +0200, Daniska Tomas wrote: > > how would you guarantee connectivity? > > > > as you have a lot of ISPs around you it should be really easy > to get some > connectivity.
