Re: [dnssd] Second WGLC for draft-ietf-dnssd-srp / does the SRP registrar check IPv6 addresses?

[Esko Dijk <[e-mail]>]

One question just came up during testing:  how can the phrase “IPv6 address(es) of the host where the service resides” be interpreted?

My take was that it could be any IPv6 address that’s registered in the AAAA record, it doesn’t need to be an actually currently valid IPv6 address (e.g. maybe the address is being configured or comes back online later), or it doesn’t need to be the address of the SRP requestor itself, for the SRP Update to succeed.
So the Requestor could do updates on behalf of services on other hosts, in theory.

An alternative view is that the SRP registrar may check the IPv6 address, and may check that is an address held by the SRP requestor. (That would seem not ok to me – too restrictive.)

Esko

The other changes are not urgent, as you say. Good call. So it’s ok with the minor changes per your response below.

Thanks. I’ve actually changed my mind about the IANA comment—I was feeling a bit overwhelmed last night, but that’s no reason not to include it. :]


Section 8.1



OLD:

IANA is requested, with the approval of IAB

NEW:

IANA is requested, with the approval of IAB (per https://www.iab.org/documents/correspondence-reports-documents/2017-2/iab-statement-on-the-registration-of-special-use-names-in-the-arpa-domain/)

I don’t want to add this reference—it’s not an RFC. We didn’t do this for previous documents that took advantage of the registry, so I don’t think it’s necessary. Is there a reason you think this is newly necessary in this case?

I think the correct place to put this is actually in the delegation section. I’ve made that change in this pull request—let me know what you think:
