Can you clarify whether it makes a difference where I delegate my domain? Regardless, I will still have to pay the registrar from whom I purchased it, correct?

Moreover, what is the point of domain delegation when the original hosting provider already allows domain management? Is it so that you can utilize a more user-friendly DNS server for management purposes?

When you purchase domain registration, delegation is often included as part of the service. Delegation allows you to designate someone else as the responsible party for managing certain aspects of your domain.
It's worth noting that hosting and registrar services are not always provided by the same company.
This is why some users opt to delegate their domains to a different DNS server rather than the registrar's servers. This can provide better pricing or more efficient management options.
Unfortunately, it's common for some companies to take advantage of customers who aren't familiar with the market value of these services.

Essentially, you don't actually "buy" a domain - you rent it. There may be an option to purchase the right to manage a top-level domain, but that can be very expensive.

Many people choose to give their domains to a hosting provider to manage, particularly if they're not familiar with DNS servers or domain management.

Unfortunately, some businesses take advantage of their customers' lack of knowledge and experience. A common tactic is to offer promotions like "two for the price of one" to lure in new customers, only to surprise them later with additional costs and fees once the domains are already established. It's important to approach these offers with caution and do your research before committing to any services.

The act of delegating your domain does not affect your obligation to pay the registrar from whom you purchased the domain. The registrar is responsible for maintaining your domain registration and ensuring that it is renewed as required. Regardless of where you delegate the domain, you will still need to pay the registrar's fees to keep your domain active.
Domain delegation refers to the process of directing your domain's DNS (Domain Name System) to a different set of name servers, effectively allowing another party to manage the DNS records for your domain. This is often done when you want to use a different hosting provider or a more advanced DNS management platform than the one offered by your registrar.

The primary reason for domain delegation is to separate the hosting and DNS management functions. While many registrars offer basic DNS management tools, these may not be as robust or user-friendly as dedicated DNS hosting platforms. By delegating your domain, you can take advantage of more advanced DNS features, such as fine-grained access controls, advanced record types, and advanced monitoring and reporting capabilities.

Additionally, domain delegation can be beneficial if you want to host different parts of your website or application on multiple hosting providers. By managing the DNS centrally, you can easily distribute traffic to different hosting environments based on your requirements.

It's important to note that even after delegating your domain, you can still manage the basic DNS records through your registrar's interface, if needed. However, any changes made through the registrar will be overridden by the delegated DNS hosting platform, as it has been granted authoritative control over your domain's DNS.
