.kz is the Internet country code top-level domain (ccTLD) for Kazakhstan.
Registrations can be made directly at the second level or at the third level beneath categories which have specific restrictions, and are generally limited to Kazakhstan-related entities.
In March 2018, new Rules went into effect and since at least 2021, these rules are being enforced. Especially Rule 16 subsection 6 is being enforced:
Example: DNS for domain www.EXAMPLE.kz cannot point to a web page being hosted in a member country of the EU. In such a case, the registry for EXAMPLE.kz will be suspended a short period and then deleted.
In June 2011, Google redirected all traffic from google.kz to google.com in response to a demand issued by the Kazakh Ministry of Communications and Information that requires all .kz domain names to operate on physical servers within the borders of Kazakhstan. Senior Vice President Bill Coughran said "creating borders on the web raises important questions for us not only about network efficiency but also about user privacy and free expression." By hosting google.kz only on servers inside Kazakhstan, "we would be helping to create a fractured Internet."
During the first half of 2017, google.kz has returned to be generally available.
Main article: .қаз
A second country code top-level domain, .қаз ("qaz") for Kazakhstan is now active. It is used with web addresses using Cyrillic letters. It was launched in March 2012, when the first site, a test site ("test.qaz"), was activated.
