I’m sorry, but there currently isn’t information or official sources that can validate the existence of a top-level domain (TLD) named “.ollo”. Top-level domains are extensions that are found at the end of web addresses, such as .com, .edu, .org, and are controlled by the Internet Assigned Numbers Authority (IANA) in a root zone database. The database includes Generic Top-Level Domains (gTLDs), Country Code Top-Level Domains (ccTLDs), and Infrastructure Top-Level Domains.
There are also sponsored Top-Level Domains (sTLDs) which are specialized domains defined by a sponsor representing a specific community that is served by the domain. Examples include .gov, .edu, and .museum. As of now, there is no official record or documentation showing “.ollo” as a recognized or in-use TLD in the database.
The process to create a new TLD is carefully regulated and moderated. Organizations have to apply during an open application period from the Internet Corporation for Assigned Names and Numbers (ICANN), and there are specific requirements, including a non-refundable evaluation fee.
ICANN launched the New gTLD Program in 2012, which saw the introduction of new gTLDs into the Internet’s addressing system. There were over 1900 applicants initially. After a rigorous evaluation, objection, and dispute resolution processes, hundreds of new gTLDs have been delegated into the Internet’s Root Zone.
ICANN’s plan to continue to expand the domain name system and possibly add more gTLDs in the future. However, “.ollo” has not been mentioned or included in any of these future plans yet.
This information has been taken from the following sources: “About Top-Level Domains” and “New gTLD Program” from the ICANN official website, “Root Zone Database” from the official IANA website.
You may be able to use “.ollo” under certain circumstances. For example, some companies use special TLDs for internal purposes, or you could attempt to register “.ollo” as a new TLD during ICANN’s next open application period. However, keep in mind that the application process can be expensive and time-consuming, and ICANN does not guarantee that your TLD will be approved. It would also be advisable to seek legal advice before proceeding.
