So my view of it is the same as current practice and laws (at least in US) which require business (including DBA) registrations in county/state registrar and requirying and making public corporate records, including address of the company and list of its officers.
Interesting how many companies are "parked" at a lawyers office, i.e. the official address of the company is that of it's legal firm. One wonders why an abuse organization would not use this same tactic and register a legal firm as the administrative contact. This is entirely separate from the operational issue of who controls the nameservice for the domain and who controls the routers and servers referenced by A records in the domain. That is not something that a registry can help with. Granted, it would be good to have a real technical contact for every domain that gets you to the same people who control nameservice etc. However, that will always be secondary information. The network itself is the primary contact information for a domain. Every nameserver has an IP address whose connectivity can be tracked through the network. Same thing for mail servers and anything else with an A record. This means that operationally it is far more important for the RIR whois directory to have working technical contacts. Fortunately, the RIRs do regularly put some effort into keeping their whois listings up to date. If more people would speak up coherently on this issue then perhaps we will see the day when only accurate contact info exists in the RIR whois directories. As for domain name registries, they are not terribly relevant for operations, just for serving legal documents. --Michael Dillon
