Some internet service providers seem to provide "external dns hosting". How does it work? And what would you use it for?
I don't really know what else I should write about my question.

An external DNS is a publicly accessible third-party domain name server that's generally open for anyone on the internet to access and update. External DNS allows you to query for the IP address of a domain. An external DNS provider is also known as a public DNS provider.
DNS hosting is a type of network service that provides domain name system resolution services. A DNS hosting service builds, operates and provisions domain name servers, which are used and integrated with domain name registrars, Web hosting services and Internet service providers (ISP).
A DNS host provides the authoritative nameservers that answer queries for your website. Without a DNS host, your domain couldn't be found on the internet. There are free, cheap, and premium DNS providers, all of which offer a different customer experience.
This tends to confuse most people, because they end up thinking the two are one in the same. In a nutshell, web hosting is essentially the space where your website files are stored. While DNS hosting is what connects users to the site and keeps the domain online.
What they mean is that they allow you to use a DNS server for your domain that is not one of their own.
Generally a service provider will have some kind of web form and/or API to enter information into DNS for your domain. This information will then be served by DNS servers under control of the service provider.
If they offer "external DNS hosting", they will point your domain to another DNS server (that you specify) instead.
One reason for wanting this could be that you want to use a more advanced DNS service then the provider itself offers. Route53 comes to mind.
You might also be concerned about the same party controlling both your service and the domain allowing it to be accessed. Imagine the provider would cease to exist: you could restore your service with any other provider but would be unable to make your domain point to it.
