.top

.top is a generic top-level domain, officially delegated in ICANN's New gTLD Program on August 4, 2014.

The domain name extension .top is managed and operated by the .top registry (registry backend ZDNS) which belongs to Jiangsu Bangning Science & Technology Co., Ltd. in Nanjing, China, and can be registered by anyone since November 18, 2014 without special requirements.

A second level domain under the top level domain (TLD) .top can consist of digits, letters, hyphens and specific special characters while it can have a length of 1 up to (a maximum) of 63 characters. Like most other TLDs, it can be registered for a period of at least 1 year up to (a maximum) of 10 years in advance. The private registration (WHOIS privacy) of .top domains is supported, as is the ability to register internationalized domain names (IDNs), which include the character sets Arabic, Chinese (simplified and traditional), French, German, Japanese, Russian, and Spanish.
