Currently, there is no top-level domain (TLD) known as “.ollo”. Top-level domains are essentially the highest level of domain names in the internet’s domain name system (DNS) structure. They are the last part of a domain name. For instance, in the domain name www.example.com, the TLD is “.com”.
In general, TLDs are classified into two categories: generic top-level domains (gTLDs) and country-code level domains (ccTLDs). The gTLDs, such as .com, .org, .net, are used globally and available to any individual or organization worldwide. On the other hand, the ccTLDs such as “.uk” for the United Kingdom, “.de” for Germany, “.it” for Italy, are meant for specific countries or territories.
The organization in control of TLD structure and approval is the Internet Corporation for Assigned Names and Numbers (ICANN). ICANN maintains a list of valid TLDs. New TLDs can be proposed and approved through procedures established by ICANN. Some new TLDs in recent years include .app, .blog, and .google.
However, as per the latest list from ICANN (available at data.iana.org/TLD/tlds-alpha-by-domain.txt), there is currently no TLD known as “.ollo”. Therefore, you cannot currently create or host a website with the .ollo extension.
This might change in the future if a company or organization named Ollo applies and gains approval for .ollo as a new gTLD. For instance, Google has its own gTLD, .google, because it went through ICANN’s application and approval processes. If such a change would happen, it would be announced publicly by ICANN and the entity that applied for the TLD.
In conclusion, while there are countless gTLDs and ccTLDs available for various purposes and regions, “.ollo” is not currently one of them. However, this could change in the future if a successful application for such a TLD is made to and approved by ICANN.
