 ExternalDNS's sources of DNS records live in package [source](../../source). They implement the `Source` interface that has a single method `Endpoints` which returns the represented source's objects converted to `Endpoints`. Endpoints are just a tuple of DNS name and target where target can be an IP or another hostname.
 
-For example, the `ServiceSource` returns all Services converted to `Endpoints` where the hostname is the value of the `external-dns.alpha.kubernetes.io/hostname` annotation and the target is the IP of the load balancer or where the hostname is the value of the `external-dns.alpha.kubernetes.io/internal-hostname` annotation and the target is the IP of the service CLusterIP.

 This list of endpoints is passed to the [Plan](../../plan) which determines the difference between the current DNS records and the desired list of `Endpoints`.
