True, but before this can happen, someone has to develope it
first. And that can lead to long and extensive discussions which
is best done with a beer and some good food. =:o)

But of course also mere user (like me) are welcome to the Debian
Treff. Meetings are usually on the first tuesday in a month in
the Restaurant St. Gallerhof near Zuerich HB, Tramhaltestelle
"Sihlquai".

[swinog] nic.ch no NS

[Daniel Rechsteiner]

Hi everyone,

nic.ch seems to have dropped out from the .ch root servers:

dig @130.59.1.80 nic.ch ns

does not give me any nameservers. Also "whois nic.ch" does not show any 
name servers (although the domain still exists).

nic.ch is in the ch zone itself. So it's not a zone of its own.

You will find it in whois so that people see that it's not available
anymore.

btw. SOA record reveals that:

Hhmm... in times long gone, it was possible to register  MX
records for domains that were only used for mail directly in the CH tld.
This was later stopped, claiming the tld should exclusively be used for
domain delegations, not direct resource records. While I understand the
intention of putting nic.ch directly as a resource record into .ch,
isn't this a violation of that rule that was established then?

Cheers,
Markus

Thanks. I suspected something like that, so I compared this to other 
ccTLDs and it's different there, e.g. for nic.fr and denic.de you get NS 
records:


dig @ns1.denic.de denic.de ns
dig @ns1.nic.fr nic.fr ns

Why is this different for nic.ch?

My colleague daniel has already gone home, so I'll chime in here as
the person who included nic.ch in the ch zone a few years back :)

To avoid unnecessary redirection for the resolution of the ch name
servers, which are part of the nic.ch domain (a.nic.ch, b.nic.ch
etc). If nic.ch were a zone itself, we would need to make it as
available as the ch zone to avoid certain failure modes.  This would
suggest to host it on the same set of servers that ch lives on.
That's achieved automatically by making nic.ch part of the ch zone in
the first place.

The se TLD does the same thing with ns.se, btw.

Interesting. I never noticed this.

Thanks for the explanation, always nice to learn something new.

I'm not going to comment this, but maybe the following anecdote will
make you feel better.  I originally wanted to use ns.ch for the ch
name servers.  This was turned down internally because it would
violate our "two-letter second level domain rule", which, I'm sure you
know, makes these domains unavailable for registration with the
exception of the "Kantonskürzel", which are assigned to the proper
authorities.

So the domain ns.ch is kept available in case the cantons of northern
switzerland ever fusion into one big one. Very clever, reveals a lot of
foresight!
