Hello Jørgen, my responses to three emails from you to the lists, jorgen at hovland.cx (Jørgen Hovland) wrote: > Will it not satisfy your needs placing 200 servers at 100 (numbers randomly > selected) MCI locations world wide using IP space assigned by MCIs /32? Certainly not - why should one be satisfied with such a pseudo-solution? A service provider (we _are_ talking about Internet infrastructure service providers currently, keep that in mind) that has come to the conclusion they want to "anycast" (aka shared unicast) their services, surely has thought about going to a big ISP before and decided that that' not what they want. > Or is this discussion simply about the fact that the /32 prefix is not yours > and you want to use your "own"? It is - currently, talking DNS providers - about the fact that you cannot accumulate too many server addresses in a DNS UDP packet. > Either way, there is no difference here network wise?

Sorry, but the fallacy of your argument is so obvious that the words fail me here. > I am against a policy that would let LIRs receive prefixes from RIRs when > the intention is to use the prefix for anycast. I have hopefully shown that > you don't need a dedicated prefix for that. No. You have shown that _you_ don't need that. You try to decide here how other people run their services. I honestly believe that's none of your business, but up to the respective service provider. You can give them good advice, of course. But you must be open to accepting arguments for the way they intend to do it. jorgen at hovland.cx (Jørgen Hovland) wrote: > You will always be forced to obey the rules of whatever provider you are > using, ISP or IXP.

The problem arises when the sole ISP's routing policies are insufficient at _any_ point in time. > Nameservers are not the only > anycast service so it would be tricky to discuss this in general. DNS is a special service (UDP packet size stuff) and needs a special solution - unfortunately. jorgen at hovland.cx (Jørgen Hovland) wrote: > Hi, > > -----Original Message----- > From: Kurt Erik Lindqvist [mailto:kurtis at kurtis.pp.se] > Sent: 13. november 2005 15:32 > > >In the first scenario you are forced to the routing policies of ISP x > >and only to the locations of ISP x.
