1. A system, comprising:
one or more computing devices, respectively comprising at least one processor and a memory that implement a dangling domain name system (DNS) pointer detection system, configured to:
monitor respective unbinding of DNS domain names of resources hosted in a provider network;
determine a list of unbound DNS domain names using the dangling DNS pointer detection system, wherein the list includes the DNS domain names that were previously bound to the resources hosted in the provider network;
identify, based on the list of unbound DNS domain names, one or more dangling DNS domain names;
send an alert indicating the one or more dangling DNS domain names based on the identification of the one or more dangling DNS domain names; and
prevent the one or more dangling DNS domain names from being bound to new resources without receipt of approval associated with an account of the provider network previously associated with the one or more dangling DNS domain names.
