Again: Do not confuse the transport with the update mechanism. We get
quite a few messages updating multiple objects, or quite simply dumping
a locally stored database onto us. We detect and ignore noop updates.
To give you an impression of the update load I cite from our 1994 annual
"The RIPE NCC maintains the RIPE network management database containing
information about IP networks, DNS domains, Routing Policies and the
appropriate contact persons. At the end of 1994 the database contained
63490 objects. During the year the Database answered slightly more than
2.2 million queries and processed 23203 update requests for 227933
objects. During 1994 the database software has been re-designed and
re-implemented to support classless IP addressing as well as routing
registry functions. The software is now being used by routing
So the average number of objects upodated per update request is aout 9.

It is not because our (main) user community is in Europe. It is because
turnaround on the mail interface is immediate. Actually people have
mentioned to me that they prefer e-mail because it leaves nice local
audit trails of who did what at no extra cost.

You mean in real time? Or periodically. The latter can be done.
Again: You are looking at a highly distributed database problem.

Our replies are as easily pareseable as SMTP style stuff.

The real soloution is to have reasonable responsiveness for everybody.
This is not hard to do. We have done it for a number of years.

Confusion of RR and RS again. What you need in the RR is actually even
more than immediately. You need updates coordinated in time between
multiple parties. Example: Customer changes provider effective noon

Yes. Currently this is: get the whole thing by ftp. We are working on

The RIPE whois server has an option to keep the connection open for
multiple queries. The PRIDE tools use that.

You can do most things in the client. There is a PRIDE tool for the
Some things need more query functions and they are coming.
Note that complicated query functions are a trade off with response
time in a whois server. MERIT has a server with more functionality.

At the moment you can do that most efficiently with a local copy of the
database (which is available). RIPE also supports WAIS lookups on the

The RIPE datbase has been operated for five years without authorisation
and authentication *but* with extensive audit trailing. We have had no
major incidents and three incidents of unauthorised and intentional
modifications all of which could be cleared up and fixed quickly. We
now have an authorisation framework and some simple authentication
methods implemented. Since this is in place no unauthorised
modifications have been brought to my attention. The autorisation
framework allows for a number of authentication methods and PGP is
currently being discussed. The main issue here is the maintenance of
the public keys. At the RIPE NCC we currently think they should be
stored in the database itself because other methods would create an
unacceptable administrative overhead.

The operators of those machines. Either you trust them or you don't.
Again I am mainly concerned with the RR machines and not the RS

There are multiple levels of dependency, trust, and legal relations.
The RIPE NCC and maintenance of the European RR is funded by the European
ISPs. They have no legal guarantees on its security at the moment but
I am quite sure I would hear if that left to be desired. If we would not
fix problems I am sure the NCC would experience a reduction in resources
