Re: [regext] Poll messages with unhandled namespaces (was Re: I-D Action: draft-ietf-regext-change-poll-07.txt)

Hello Ulrich

I don't know the numbers but I think you are right that most registrars don't care too much yet.
On the other hand there are some new extensions in the pipeline that use the poll mechanism. (change poll, balance etc.)

Thats why I believe it will/should become more important in the future.

The number of validating clients may be small but I don't believe that we can ignore them and send our poll message with extensions regardless of the configured login services.
Even if some of the registrars don't implement according to the standards, I think at least the registries should do so and creating a poisoned message is therefore not an option for us.

So the only alternative to deal with it is to not send the extension part and in some cases this means to not send a poll message at all.

Therefore a client has no option of knowing that he is missing out on some information unless studying the manuals of the registry...

I think that this is hindering the development of EPP Poll extensions for no good reason. Out of sight - out of mind...

Martin

Hi,

are we really sure this is a problem worth solving?
At .se registrars (with very few exceptions) fall into two categories.
- do never poll
- poll and ignore anyway

I know that we have registrars who validate, but those usually support all our extensions.

Could anybody produce numbers on registrars who do all three?
  1. poll
  2. validate
  3. do not support all extensions

/Ulrich

To be clear the domain info response will be sent just without the DNSSec part. Therefore a not DNSSec interested registrar will just not see the DNSSec configuration but all the rest of the domain info resData. I don't see a problem with that.

In our case a registrar currently needs to be accredited by us (DNSEC_ENABLED) in order to successfully login with DNSSec extension configured and he will only be able to transfer a DNSSec domain to him if the configured DNSSec at login.

In case he is DNSSec enabled but still logs in without this extension he will get a failure with error message similar to  “Not allowed to transfer DNSSec Domain” when trying to transfer a DNSSec domain to him.

So actually there is a way to know why it didn't work for him.

As a matter of fact we will have to over think this rule now because with CDS DNSSec Data can be configured by the DNS-Operator of a domain as well (which does not need to be the registrar) . So a domain of a non DNSSec accredited registrar could end up with  DNSSec data. In case he is DNSSec accredited he might be interested to keep his DNSSec Data synchronized with the data at the registry originated by CDS. That is exactly our use case where we want to use the change poll extension.

James, please, again, take into account some real life examples that happen today:

registries restrict the use of secDNS at login for only the registrars having passed
a specific accreditation test (trying to login with it without prior registry vetting triggers an authentication error, so the registrar can only do its business if it removes this extension from list at login)
thus, in your case (just removing the content), a registrar not wanting to do DNSSEC and not wanting to transfer
to him a currently DNSSEC-enabled domain will have no way to know that.

And saying to registrars: "then pass registry accreditation tests to be able to login with secDNS and see **others** domain names with secDNS data while you do not want to do any DNSSEC related stuff", is certainly not going to fly...

As long as we take into account only some cases and not others we will never be
able to deliver an extension used by multiple registries.
Also, before anything happen I will be very interested by intention of support
(which means deployment) from registries.

Otherwise, like I said, this problem exists since EPP started so it is not new,
and it seems the current status quo fits most of the player (due to the number of people
having participated here), so we are maybe devoting resources to trying to design
something perfect... that noone will then use :-(
