In general all domains worldwide can be managed centrally through managed IP. Moreover, under most country extensions your corporate headquarter can be registered as the domain owner (exceptions are those countries with a local registrant/admin-c requirement).
A sophisticated Whois-strategy is a fundamental part of any domain strategy and...
- generates sound legal protection (e.g. domain owner equals trademark owner),
- channels domain requests to the appropriate person/department,
- makes your portfolio future-proof which will reduce your costs.
In addition, historic data will be detected and replaced (e.g. admin-c is a former employee, company legal form does not exist anymore).
