DNS hosting service is the service than runs DNS servers.

DNS hosting service is the service than runs DNS servers. Most, but not all, domain name registrars include DNS hosting service with registration. Free DNS hosting services also exist.

DNS hosting service is optimal when the provider has multiple servers in various geographic locations that provide resilience and minimize latency for clients around the world. By operating DNS nodes closer to end users, DNS queries travel a much shorter distance, resulting in faster Web address resolution speed.
