Quick Update
• CRISP WG– base requirements done– protocol selection done– moving forward with IRIS
• draft-newton-iris-ereg-01.txt– incorporated comments received for –00.– removed cruft from section 6– updated to be current with iris-core -04

Why?
• Is a whois service needed for ENUM?– Will ENUM just be a small community of
providers?– Will all ENUM interactions remain intra-
national?• cross-border abuse?• cross-border coordination?
– Will there be delegations to private entities?• b2b & e2e coordination?

Who?
• Who will resolve ENUM problems?– To resolve an issue, does the end-point sys admin have
to rely on the upward chain?
• Who do you contact?– Large network operators have different sys admins for
different purposes: abuse, noc, etc…• Which one is which?
– Is that SOA a SIP address or an SMTP address or an XMPP address?

What?
• Just what can go wrong?– Messed up MX records are fairly common, so
what’s the likelihood of encountering a messed up NAPTR or SRV record?
– Will fat-fingering cause incorrect delegations or bad NS sets at the zone apex?
• What will we do about abuse?– Will ENUM will be easy prey for war-dialing
SIP spammers?

This Proposal
• Specifies a vector for coordination.– Not mandating “the” vector for coordination.
• Is one part of the answer.– No protocol/technology can be the whole answer.
– Policy plays a major role.
• Attempts to be policy-neutral.– Providers have differing requirements based on
jurisdiction.

Applicability
• Public-facing– account for data miners and abusive users
• Privacy– pluggable authentication for adaptable authorization
• Structured– well-understood multiple methods of alternative contact– I18N
• localization of protocol elements• multiple language contact equivalents
– standard queries and results
