000Domains is owned by Dotster, powered by Domain.com, which means creating a zone on Domain.com also creates a zone on Dotster and 000Domains (and vice versa). For example, 4orty3.net uses Dotster's DNS, however ns1.domain.com and ns1.000domains.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 (you can purchase something then cancel to get an account).
To perform a takeover on 000Domains, get an account on Domain.com and add the zones there (which will activate the zone on 000Domains).
