Hank, These whois servers uses an output format "based" on RPSL with added extensions for organizations and dns delegation status. The whois server at the .BR registry (also the NIR for Brazil) doesn't provide country information because it's implicit as it only provide information for Brazil.

Can you point me to documentation on the extensions? Any plan on RFCing?

Implicit is fine for humans but for automated scripts, couldn't it be made to have country=BR for all your inetnum entries? Thanks, Hank

No. There is no public documentation for this. There is an effort at the IETF [1] trying to standardize the discovery, output format and the query semantics. Some time in the future these servers will be "CRISP" compliant.
The whois server at the .BR registry (also the NIR for Brazil) doesn't provide country information because it's implicit as it only provide information for Brazil.
Implicit is fine for humans but for automated scripts, couldn't it be made to have country=BR for all your inetnum entries?
We'll look at this for our next server release,

When I was running a whois server we discovered that not all local people appeared to want to use a local address. Some of them had head offices used for billing, and the like, that was in a different country so having the country code was useful even for humans. Mark.

So how should whois users understand country information in the database? Should they interpret it as "my network is located in this country"? Alternatively, should they interpret it as "our corporate offices are in this country"? Increasingly, there is a discontinuity between the two as international corporations run networks in many countries from an HQ in just one. If people updating the information in whois have different ideas about its meaning then users of whois its value might be lower than expected.

Got something really weird going on and I need a bit of help from someone who is really good with dns. Domain elby.ch seems to resolve from some DNS servers but not from others. Can you see anything that might break dns resolution for this domain? Specifically it appears NT4 dns servers with SecureResponses turned on. Please feel free to answer me offlist. Geo.

Domain elby.ch
See: http://www.dnsreport.com/tools/dnsreport.ch?domain=elby.ch There is a warning for parent servers: Your NS records APPEAR to be: ns2.elbyns.de. [62.116.162.15] [TTL=80024] ns1.elbyns.de. [62.116.130.76] [TTL=80024] NOTE: These records may be inaccurate, since the parent servers (tulku.nic.ar.) do not know the NS records for elby.ch (or give a referral to other DNS servers)! This may cause other tests not to work properly, such as the 'Nameservers on separate class C' test. This may or may not be related to your problem. -Hank

Eh? I don't see a delegation to tulku.nic.ar. anywhere down the delegation chain. . says ch nameservers are: NS.APNIC.NET. 2D IN A 203.37.255.97 DOMREG.NIC.ch. 2D IN A 130.59.1.80 MERAPI.SWITCH.ch. 2D IN A 130.59.211.10 DNS.PRINCETON.EDU. 2D IN A 128.112.129.15 RIP.PSG.COM. 2D IN A 147.28.0.39 TULKU.NIC.AR. 2D IN A 200.16.97.77 CCTLD.TIX.ch. 2D IN A 194.42.48.120 all these nameservers agree that elby.ch nameservers are: elby.ch. 12H IN NS ns1.elbyns.de. elby.ch. 12H IN NS ns2.elbyns.de. Both these nameservers return identical data to an 'any' query type. matto On Mon, 20 Oct 2003, Hank Nussbacher wrote: At 11:56 AM 20-10-03 -0400, Geo. wrote:

Domain elby.ch
FWIW, this is often a good site to use when troubleshooting such issues: http://dnsreport.com/
The name servers for the domain elby.ch do not reverse resolve. For example: ns1.elbyns.de resolves to 62.116.130.76, but 62.116.130.76 does not resolve back ns1.elbyns.de. It's not clear through the RIPE Whois search (this IP block is within a RIPE range) who does name service for the IP block. Contact your local provider to arrange for the IP to reverse resolve properly. K -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Geo.
