If we opt for the root NS to have its own AS then there is no barrier to people offering identical routing policy for the LINX and the NS. If it shares the LINX AS then it will be impossible to have different policy for LINX and the NS. So, if there is a possibility that there will ever be a requirement to have different routing policy for the NS and the LINX it would seem wise to give the NS its own AS. It may be moot in as much as it's probably desireable to achieve 'root server connectivity quality' for the LINX AS, but the seperate AS for the root server would preserve some flexibility.

proposed agenda - DNS WG session at RIPE26
by Ruediger Volk 23 Jan '97

23 Jan '97

Dear colleagues, please find below a proposed agenda for a DNS WG session at the upcoming RIPE26. 1. Opening & administrativa 2. Agenda bashing 3. Report from San Jose IETF (IRE(?) BOF) 4. Report from IAHC proposal debate (mailing list) 5. Collect & prepare RIPE feedback to IAHC 6. proposed root server from VBCnet 7. technical DNS issues (a) Status new DNS standards work (dnssec, dnsind) (b) new software status (c) any recent technical problems to discuss? 8. reports/news from various top level domains 9. AOB For the reporting items (3, 4, 7*, 8) I would like to ask for volunteers who participated or observed the events or processes to identify to me the kind offer to present a short summary report or position. I have included items 7. and 8. but consider those optional; if neither reports are offered nor priority requests for discussing specific issues are received I think these items should be dropped - as time will be short for the remaining items anyway.

Ah, the center of Europe is between NY and Washington DC and that is reason enough to have _yet another server_ there. Great.

And it will stay that way on this continent, where for > ages and ages already national issues have dominated what Sorry, I don't understand something. Why cannot a region set up a root name server for its private use? Users who can reach it fast are advised to put the address of this server into named cache file, others not. Generally peoples might select a appropriate set of root name servers and put them into cache file. This might be the menu: "Veeery official" servers: a.root-servers.net ... i.root-servers.net "Official" continental servers: a.europe.root-servers.net b.europe.root-servers.net k.europe.root-servers.net q.asia.root-servers.net "Semi-official" regional servers: s.north.europe.root-servers.net n.south.europe.root-servers.net "International ISP" servers: provider1.west.europe.root-servers.net provider2.west.europe.root-servers.net etc. There would be suggested root NS sets tailored for each region. Asian resolvers probably are not interested in a European root NS and vice versa. The only thing to discuss whether Internic does allow to download the zonefile for these hosts. Semi-official and International ISP servers may be tertiary root name servers even. OK, this idea may be junk. I just wished to start a brainstorming. Keep flame on minimum. Thanks for your patience. Gabor ------- Another funny idea, related to this one: The DNS itself could store a pointer to a suggested cache file specific to the requestor's address. (And a version number too.) E.g. cache.arpa. TXT "14,ftp://ftp.internic.net/pub/SOME_FILE" 193.cache.arpa. TXT "71,ftp://ftp.ripe.net/root-ns/europe.cache" 6.193.cache.arpa. TXT "4,ftp://ftp.hungarnet.hu/pub/hungarnet.cache" Users are suggested to find the longest name matching your address, and use cache file pointed by it.

I agree, but at the cost of an additional router. Due to the nature of the full routing we need for theses AS(es), a 64Mb router is a requirement eventually anyway, but it is not a LINX budget item at present, and while there have been lots of offers of server hardware for the root NS, there have been none to date of a router. I suggest we make the ASes the same for now, but split them when a clear requirement arises. At that point we will hopefully have a route server box to take over various of the collector functions.

Re: 2nd Root Server in Europe (fwd)

Taking a step back from the detailed discussion, it seems we don't have any major objections from the UK community to the proposals for deploying this I circulated last week, so I feel happy to take them to the RIPE DNS WG to take them a step further. We have offers of resources from VBCnet and NOMINET in the form of server hardware and operational support, and various LINX members as regards transit. We have support in principle from LINX, ISPA & NOMINET. Here's what I think the outstanding issues are: - fitting it all in to the European and Global picture: - for further discussion - routing policy for the NS ? various points here: - do we put the server in the LINX AS, or create a new one ? For this point it is worth remembering the reason we have the LINX AS in the first place, namely: 1. To make the LINX LAN prefix visible to the rest of the world 2. To give the LINX secretariat Internet connectivity 3. To have something everyone can peer with to gather useful stats in the collector. I don't think there are any sacred cows for any of these here - if we adjust the LINX policy to meet requirements of the root NS rather than the other way around, I don't think we break either of 1 or 2. I don't think it breaks 3. either, but this requirement will go away when we have a route server in any case. i.e. I am very appreciative of the existing LINX members who give transit to the LINX, but, it would not break my heart to have the same connectivity/policy for the LINX as a UK-based root NS, and would understand if the existing providers did not want to fully transit a root servers' traffic - we have had enough offers to transit the root NS I do not see this as a problem. - how many members should provide transit to the root NS AS ? we have appear to have 2 schools of thought here, namely that either everyone should transit the thing to spread the load as evenly as possible, or that we should only have a small number to keep the routing deterministic (there's also a 3rd more wacky suggestion to do some special local hack, but I tend to agree with Paul Vixie's comments on that). My view is that we have to be careful about too many members providing transit, as we can easily finish up with lots of views of the way to the LINX AS with equal path lengths, but non-obvious tie-breaks, leading to hard to predict connectivity. Also increasing the number of path/prefix products in the global routing tables is in any case ecologically unsound. Perhaps the solution is for a small number of well-connected LINX members to provide universal transit, but for an additional group to provide additional transit to specific places (like the Nacamar offer). (Further discussion of server routing policy is probably best confined to technical forums, i.e. maybe nom-dir and ispa-com want to be dropped off the distribution.) - server for just "." or TLDs ? This kind of ties in with routing policy, in that those providing transit have potential concerns about traffic levels generated by a TLD server . One solution here might be PeterL's suggestion of seperate servers for TLD and ".", with different members providing different transit to each. The TLD server does not need to have its own independent address space in the same way the "." one does. I think we can still get away with having them in the same AS, though there is some risk of asymmetry here. All we need is an additional offer of server hardware..... - router hardware We do need to think about upgrading the collector to a 64Mb- capable box, most likely a 7200. If we think that a 100Mb connection for the server is needed, then the is a spare slot in the collector for an FDDI or 100baseT card. I'm sure there was another point to make, but being in the RIPE terminal room is distracting me a bit. More discussion of this here tomorrow. Keith

The .COM and .NET domains are very large, they have many querries, but the . nameservers serves the universe. Suggestion; Separate the . (root) from the next level (.country, .net, .com) servers.. So, instead of putting ONE host on the network behind the router, put TWO, and the second one could handle the second level domains you wish. Maybe there should be a THIRD host to serve the country toplevel domain (.uk in this case) and maybe toplevel for other countries the region. (.nl, .es, etc..) Hosts are cheap, running them with a quality service is more expensive, but the number of users affected by the performance and availiabilty and performace are VERY high... > > > Shared resources has to bee keept as neutral as possible, and having > > > for example a root-name-server behind it's own router attached to a well > > > recogized public exchange point seems to be the best avaliable > > > implementation today. > > > > This is in fact exactly the physical arrangement that we have proposed: > > a root name server on its own class C one hop off the LINX. > > Not from a routing policy point of view - will you put the root > server in a seperate AS, or will connectivity be constrained by > your peering/routing policy ? The nameservers has to be in their own AS, behind their own router(s) and account for traffic to be in the 400kbps in / 700kbps out range and estimate growth to 10% month. So full-duplex FDDI or full-duplex fast Ethernet is a requrement. The peering policy of this as should be something like; Peer with anyone who request to peer. Maybe it even should accept circiuts from those who just want to have good connectivity to the nameservers, but don't care about the particular exchanage point. ------------------------------------------------------------------------ I would suggest that once everyone agreed on a workable model that we also implement that for other root namseservers. --Peter

This was discussed at the IEPG meeting in July and again in December. The issue at the time was to provide advice to IANA as to the potential siting of additional root name servers - the advice so provided was along the lines of siting one server in the UK with a potential system host of LINX and siting a second in Japan, with a potential host of WIDE. The discussion was initiated by Bill Manning and the notes of the Montreal meeting are at http://www.iepg.org Thanks Geoff

Daniel, I've had a number of discussions with Bill Manning to facilitate this, and hosting of this server was again discusssed and endorsed at the LINX meeting today. However, I am rather surprised to hear of the involvement of VBCnet and ISPA - despite Jim regularly attending LINX meetings and being active in LINX mailing lists, he has not mentioned anything about either of these. Normally the ISPA does not concern itself with technical or infrastructure matters. LINX policy, which was endorsed at the two recent IEPG meetings, is that the proposed root server would be in the LINX neutral AS rather than that of any particular member - clearly we welcome VBC's offer of resources, but I am not sure the other LINX members would be quite so supportive of this if they felt one member was being a chance they also might also want. With this qualification LINX remains highly supportive of this proposal and I'll do my best to facilitate it. I will be at the RIPE meeting next Mon and Tue, and hope Jim will be there to clarify any confusion.

Re: 2nd Root Server in Europe (fwd)

> LINX policy, which was endorsed at the two recent IEPG meetings, is > that the proposed root server would be in the LINX neutral AS This is was was discussed at the IEPG meeting, and the concensus was that "common resources" should be attached to public exchange points trough a dedicated router in a neutral way. Shared resources has to bee keept as neutral as possible, and having for example a root-name-server behind it's own router attached to a well recogized public exchange point seems to be the best avaliable implementation today. Thus all ISP's present at that echange point could peer, regardless of their peering policies to other ISP's and as there is no other service than the nameserver is behind that router, and I'm sure all of them (the ISP's peering) will give transit for the prefix used by the nameserver to other parts of the network. --Peter

2nd Root Server in Europe
by Daniel Karrenberg 13 Jan '97

13 Jan '97

Dear colleagues, I have received an informal query from IANA about RIPE's opinion about the placement of a second root name server in Europe at the LINX operated by VBCnet. This should be discussed at the next meeting. Personally I think that placement at the LINX makes good sense because of current network topology.

To date I have received no reply at all, other than something from a robot promising a reply from a human being within ten days; this of course never came. I have been just now been asked to report back to the board of the UK Internet Service Providers Association regarding this request. Would it be possible for someone at IANA to give us some indication of what your response is likely to be?
