TLD, **Top Level Domain**, is the identifier following the domain name & starting with a dot (.) with the more familiar TLDs being .com, .org, .net, and many others. 

All existing TLDs can be found at https://www.iana.org/. 

For example, this is the typical delegation record for [a .nyc TLD](https://www.iana.org/domains/root/db/nyc.html).

##### For a New TLD
---

Setting up a Top-Level Domain (TLD) is a complex process that involves significant technical and administrative considerations. It requires coordination with Internet Assigned Numbers Authority (IANA), ICANN (Internet Corporation for Assigned Names and Numbers), and other relevant organizations. The process generally involves the following steps:

1. Evaluate the Need: Determine the purpose and justification for creating a new TLD. Consider factors such as market demand, community interest, and technical requirements.
    
2. Develop a Proposal: Prepare a detailed proposal outlining the intended use, policies, and management structure of the TLD. This proposal should comply with ICANN's guidelines and requirements.
    
3. Funding and Resources: Ensure you have the necessary financial resources and technical expertise to establish and maintain the TLD. This includes infrastructure, registry services, and operational support.
    
4. Application Submission: Submit the application to ICANN during the designated application period. The application process typically involves a comprehensive evaluation, including technical, financial, and operational assessments.
    
5. Registry Operator Selection: If the application is approved, select a registry operator to manage the TLD infrastructure and operations. The registry operator will be responsible for maintaining the TLD's domain name database and providing registration services.
    
6. Contract Negotiation: Engage in contract negotiations with ICANN to finalize the terms and conditions of operating the TLD. This includes agreements on fees, compliance, dispute resolution, and other contractual obligations.
    
7. Technical Setup: Work with the registry operator to set up the technical infrastructure required for the TLD. This includes configuring domain name servers (DNS), establishing registration systems, and implementing security measures.
    
8. Launch and Promotion: Plan and execute the launch of the TLD, including marketing and promotional activities to attract registrants. Communicate the availability and benefits of the new TLD to the target audience.
    
9. Ongoing Operations: Continuously manage and operate the TLD, ensuring compliance with ICANN's policies and industry standards. This includes domain name registrations, renewals, transfers, and providing support services to registrants.
    

It's important to note that setting up a TLD involves significant costs, legal requirements, technical expertise, and compliance with ICANN's processes. It is a complex undertaking that typically requires the involvement of a qualified and experienced registry operator.
