How often do you think companies register domains for defensive reasons? For example, the well-known manufacturers Hitachi registered 'Hitachi' in all the extensions available for Indian domains:

Hitachi.in
Hitachi.co.in (main website for Hitachi in India)
Hitachi.net.in
Hitachi.org.in
Hitachi.firm.in
Hitachi.gen.in (redirects to Hitachi.com)
Hitachi.ind.in

Except for Hitachi.co.in and redirecting Hitachi.gen.in, all the other domains do not resolve to an actual website. This suggests that the domains were registered for defensive reasons.

Also, it's interesting to note (although not surprising) that of all the Indian domains they registered, Hitachi choose to use .co.in as their main India website.

I think registering domains for defensive reasons was a smart move by Hitachi. With regard to Indian domains, do you think a lot of other companies are registering domains for defensive reasons as well?
