Extended information:

Top-level domains are divided into two categories:

First, national top-level domains (nTLDs), and currently more than 2 countries have allocated top-level domains according to ISO3166 country codes.

second, international top-level domain names (iTDs), such as. Com for industrial and commercial enterprises,. net for network providers,. red for good luck, enthusiasm and diligence, and. org for non-profit organizations. At present, most domain name disputes occur under the top-level domain name of com, because most companies go online for profit.
