DNS WG at the 17th RIPE meeting
by Francis Dupont 11 Jan '94

11 Jan '94

I am collecting the ideas for the DNS WG agenda... First we have the still open points: - a second root name server in Europe (nothing new ?) - IPng support (new proposal and code for TUBA/CATNIP/NSAP, perhaps something for SIPP ?) - last BIND software (version 4.9.2 is in final beta-test) - DNS for Windows NT (I know only one thing: WNT has a resolver :-) New points: - mandatory field zone-c RIPE DB problem (cf Marten's E-mail) You can propose elements for the agenda (before next week please). Thanks Francis.Dupont(a)inria.fr

This is Ruediger's option (d). Looking at the number of syntax errors in the database currently for domains, and the population, I would even vote for (a) or (b), but this has been rejected by the dns-wg on several occassions (on very good grounds). The question was and is whether the domain objects give added information compared to what is in the DNS. With 4.9 and the TXT and RP RRs I am not quite sure if these grounds still hold ... Other opinions ? -Marten PS I have CCed the dns-wg as well ...

Query: What to do if you use an A record but can't handle mail
by arthur＠midir.ucd.ie 11 Nov '93

11 Nov '93

Gentlemen - Apologies for intruding in this manner, but I have a query for which the usual sources don't seem to have an answer. What is the collective wisdom on providing A records (for Internet access) but stopping mail access? There are a large number of machines here in University College Dublin which require Internet access but can't run a SMTP server (they're PC and the like). I want to ensure that anyone trying to send mail to them gets a prompt refusal -- what I plan to do to is provide a DNS entry like this: toaster.ucd.ie. IN A 137.43.2.29 toaster.ucd.ie. IN MX undeliverable.ucd.ie. The host undeliverable.ucd.ie doesn't exist, which should as far as I know return a prompt "can't deliver mail" message. So, is this how other people do it? Is this the right way? Is there a better way? Any and all suggestions will be gratefully received. - Arthur Green University College Dublin Computing Services Tel: +353 1 706 2456 Fax: +353 1 283 7077 E-mail: arthur(a)midir.ucd.ie

MX in IN-ADDR.ARPA domains?
by hh＠tip.net 13 Oct '93

13 Oct '93

Hi there, Now we have delegation of the IN-ADDR.ARPA domains from the root servers, similar to the delegation of the 'ordinary' domains. Before this happened there were only one single registry that handled all the reverse NS delegations, former <hostmaster(a)nic.ddn.mil>. This was easy to understand. Yesterday I spent some time trying to explain for one of our customers how the registration currently works. Well, you know the story.... Then I come to think of: Why couldn't he send a request to hostmaster(a)44.193.in-addr.arpa? The information about the hostmaster of each domain is of course already viewable in the zone files, but wouldn't it be more user-fiendly to be able to address the hostmaster of the IN-ADDR domain directly? Maybe this way of using IN-ADDR.ARPA isn't approved in applicable RFC's (I haven't checked)?

two Mediterrean TLDs dropped!???
by Ruediger Volk 28 Sep '93

28 Sep '93

Dear colleagues, I'm surprised to find that the top level domain names CY and GR (for Greece and Cyprus) have been dropped from the most recent root zone (Serial 930927 as available by FTP from rs.InterNIC.net) While all of the master servers for those TLDs - with the exception of NS.EU.NET - seem still to carry those two zones, root server NS.INTERNIC.NET does not delegate CY and GR anymore (see logs from checking with dig and host below). Checking the InterNIC whois shows that the TLD entries have been changed yesterday; probably that update sunk CY and GR as collateral damage:-) Please correct the root zone immediately and take action to have the broken zone replaced on all "infected" root servers. As of the time of sending this message serial 930927 had found it's way to NS.INTERNIC.NET, C.NYSER.NET, TERP.UMD.EDU, NS.NASA.GOV, and NS.NIC.DDN.MIL (AOS.ARL.ARMY.MIL still has 930924, NIC.NORDU.NET is still at 930922, and KAVA.NISC.SRI.COM is not responding).

RIPE NCC Temporary Registrar
by Daniel Karrenberg 23 Sep '93

23 Sep '93

Dear Jon (and others), during last week's RIPE meeting the question of start up toplevel domains has been discussed in the local registry working group. The concern (spawned by the situation in Lebanon) is that when first starting it is difficult to find a registrar acceptable to the community within the country and this could delay things very much. The RIPE NCC was asked and accepted to offer a temporary TLD registry service for start up TLDs in and around Europe as necessary. The procedure would be to wait for about a dozen registrations and then have the registered organisations agree on a local registrar. I hereby offer this service whenever you may think it is appropriate. Please note that we still feel that having a local registrar accepted by the local community is much preferrable to an external registrar. This offer is intended only to speed up the creation and population of new TLDs where necessary and appropriate. Regards Daniel

host and domain with same name
by bonito＠nis.garr.it 21 Sep '93

21 Sep '93

Hello, anyone has hints/advices about the following problem: We (GARR-NIS) have registered a new domain under .it with the following records: eurolan.it. 604800 NS ns.iunet.it. 604800 NS eurolan.it. eurolan.it. A 192.106.195.1 As you can see one of the servers (a secondary at the moment, may become the primary in the future) has the same name of the whole domain. I think this should not be a problem, but querying our server we do not get information about autoritative servers: Query about eurolan.it for record types ANY Trying eurolan.it ... Query done, 1 answer, authoritative status: no error eurolan.it 432000 IN A 192.106.195.1 On the contrary, querying the primary server we get the right answer: Query about eurolan.it for record types ANY Server: ns.iunet.it Address: 192.106.1.1 Trying eurolan.it ... Query done, 8 answers, authoritative status: no error eurolan.it 14400 IN SOA ns.iunet.it postmaster.iunet.it ( 930224 ;serial (version) 28800 ;refresh period 14400 ;retry refresh time 604800 ;expiration period 14400 ;default ttl ) eurolan.it 432000 IN NS ns.iunet.it eurolan.it 432000 IN NS eurolan.it eurolan.it 172800 IN A 192.106.195.1 eurolan.it 14400 IN MX 0 eurolan.it eurolan.it 14400 IN MX 10 relay.iunet.it eurolan.it 14400 IN MX 20 relay1.iunet.it eurolan.it 14400 IN MX 50 mcsun.eu.net Additional information: ns.iunet.it 604800 IN A 192.106.1.1 ns.iunet.it 463543 IN A 130.251.1.17 eurolan.it 172800 IN A 192.106.195.1 relay.iunet.it 14400 IN A 192.106.1.2 relay1.iunet.it 14400 IN A 192.106.1.3 mcsun.eu.net 94962 IN A 192.16.202.1 ---------- ---------- Antonio_Blasco Bonito E-Mail: bonito(a)nis.garr.it GARR - Network Information Service c=it;a=garr;p=garr;o=nis;s=bonito c/o CNUCE - Istituto del CNR Tel: +39 (50) 593246 Via S.
