Like the UK with .co.uk etc., the Cook Islands have mandatory second-level of codes to indicate the type of organisation. They are:
- .edu.ck: educational institutions
- .gov.ck: government agencies
- .co.ck: business organisations
Here's my personal dot-cock favorites:
google.co.ck
The Cook Islands' version of the world's favorite website.
budget.co.ck
The Cook Islands branch of car rental company Budget.
travel.co.ck
Cook Islands' travel agent.
