Top-level domains (TLDs) are the highest level of domain names of the Internet. They form the DNS root zone of the hierarchical Domain Name System. There are several types of TLDs, including Generic Top-Level Domains (gTLD), Country Code Top-Level Domains (ccTLD), Internationalized Top-Level Domains (IDN ccTLD), etc.
Upon research, there appears to be no recognized top-level domain (TLD) specifically titled “.AETNA” in any official records. The current and complete list of TLDs can be found on the Internet Assigned Numbers Authority (IANA) website which is the official organization responsible for maintaining the list of TLDs. At present, IANA recognizes over 1,500 TLDs, but “.AETNA” is not one of them.
AETNA, however, is a prominent American managed health care company, which sells traditional and consumer-directed health care insurance and related services. The official website for Aetna is www.aetna.com, where ‘.com’ is the TLD. This ‘.com’ TLD is one of the original and most popular TLDs, primarily used by commercial and for-profit organizations.
Many companies like Aetna though now adopt branded TLDs (like .google, .amazon), based on their brand names to increase their web presence and gain an additional level of control over their online brand experience. This trend involves a pretty substantial financial commitment for the application fee and an on-going cost to maintain registry operations in accordance with ICANN (Internet Corporation for Assigned Names and Numbers) requirements.
.auDA, Australia’s domain administration and policy authority, for instance, launched ‘.au direct’ (example.au) in March 2022 to allow Australia-identified businesses, organizations and individuals to have shorter, more meaningful domain names that are easy to remember.
In conclusion, while AETNA is a recognized name in the health care industry, it does not have its specific top-level domain as of now. It uses the widely adopted “.com” TLD for its official website.
