Explanation

Dotster is powered by Domain.com, which means creating a zone on Domain.com also creates a zone on Dotster (and vice versa). For example, 4orty3.net uses Dotster's DNS, however ns1.domain.com will resolve all records for 4orty3.net.

Per Domain.com's Knowledge Base you can add external domains if you have an existing account or if you purchase something (like hosting). Thus, to perform a takeover on Dotster, I recommend you get an account on Domain.com (buy something cheap and cancel) then add the zones to Domain.com (which will activate the zone on Dotster).

Since Dotster also owns 000domains.com creating a zone on Dotster will active a zone automatically on 000domains.com's DNS.

Needs Verification? Yes

While the documentation supports the belief that takeover is possible and their system uses the same backend as Bizland and MyDomain (which are vulnerable). We do need someone to verify that takeover is possible.
