Because that’s what everybody else are doing? That’s why we currently have 600 routes in dfz and not one per server on the internet?

Ok, but I would still like to hear from people who have tried that but had to reject the solution for valid reasons where the ISP offered you this service.

Sorry, but >the fallacy of your argument is so obvious that the words fail me here. Could you be more specific? I am sure there are ISPs that are not willing to sell anycast services, but if you have buyers then the sellers will always show up eventually. >> I am against a policy that would let LIRs receive prefixes from RIRs when >> the intention is to use the prefix for anycast.

It is good that we try to figure those out. > You try to decide here how > other people run their services. No, I am trying to prevent excessive defragmentation of the routing table. I am trying to prevent a special case of PI where you are not even required to have your own network. The requirement to this special PI case is so low that anyone would be able to apply for it - and anyone _will_ apply for it. In order to prevent that we only permit DNS? Are there any other services that should be permitted? > I honestly believe that's none of your > business, but up to the respective service provider. You can give them > good advice, of course.

So far we have two reasons why anycast prefixes, "anycast PI", should be permitted: * Bankruptcy * Routing policies >> 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. I disagree. DNS is certainly not a special service. The importance of it is however perhaps greater than many others - many, but far from all. The packet size thing is a general design problem. As far as I know, there are currently two methods to solve it: * EDNS0 * TC flag If you are going to use the packet size problem as an argument to use anycast, then I think it would be a good idea to hear reasons why none of these solutions would be suitable (also because I don't really know it myself) and perhaps if there are any other solutions that would help solving the problem? > >From that perspective I seem to see 2 aspects in the recent discussion: > > > >- you shall not receive address space for builing a service, you are to > > buy that from some "big-folk". > > > > This is an intersting point of view, and taken to the extreme will > > make us end up with a _very small_ number of _very big_ entities. > > > > Traditionally these things were called monopolies.

"All you need to do is to create a network and ask for address space.." There is no monopoly threat as long as you follow the requirements. If the requirements are too strict, then it would become a problem. Currently, I think they are not. Joergen Hovland
