What are the differences between SunONE, iPlanet and Netscape Directory Server?

When I go to docs.sun.com - Products Categories, I saw that they've documentation regarding with SunONE, iPlanet, Netscape Directory Server listed under Directory Server.

I know that they're all different directory server, but is it one newer than other? If I'm not wrong, I assumed that Netscape transformed into iPlanet, and then from iPlanet, it transformed to SunONE. If that is the case, is that mean that all of it's console and how it works should be very similar?

Thanks!
