I’m sorry, but there seems to be some confusion in your question. LANXESS is not a top-level domain (TLD). Top-level domains are the highest level in the Domain Name System (DNS) of the Internet. They appear in domain names as the string of letters following the last (or only) dot, such as .com, .net, .org, etc.
LANXESS, on the other hand, appears to be the name of a specialty chemicals company. If LANXESS had a domain name for their company website, it might be something like www.lanxess.com, where .com is the top-level domain and “lanxess” is the second-level domain.
In terms of technical description, a top-level domain (TLD) is the part of the domain name located to the right of the dot (” . “). The TLD is the most general part of the domain name. The hierarchy of domain names descends from right to left; each label to the left specifies a subdivision, or subdomain of the domain above it. For example, in the domain name www.example.com, “.com” is the top-level domain, and “example” is a second-level domain.
For a company like LANXESS, domain names are often chosen to be the name of the business, as it’s important for their web address to be intuitive and memorable for their customers.
Top-level domains (TLDs) are managed and registered by specific organizations and entities known as registries. These registries are appointed by the Internet Corporation for Assigned Names and Numbers (ICANN), a non-profit organization responsible for coordinating the Internet’s global domain name system.
Currently, there are over 1,500 TLDs available according to ICANN. These are divided into several types:
- Generic Top-Level Domains (gTLDs) such as .com, .net, .org, etc.
- Country-code TLDs (ccTLDs), which are often used for websites targeted to specific countries, such as .us for the United States, .uk for the United Kingdom, etc.
- Sponsored TLDs (sTLDs), which are proposed and sponsored by private agencies or groups, and
- Infrastructure Top-Level Domain, there is only one TLD in this group, i.e., .ARPA
To keep the architecture of the Internet reliable and robust, each top-level domain has its own set of name servers, which is essentially the Internet’s equivalent of a phone book.
