DNS Hosting

From Website Hosting Wiki

DNS hosting services are ones that run Domain Name System (DNS) servers. These are usually found with domain name registrars although not all of them offer the service with customer registrations. There are some free DNS services also available and almost all DNS services run on the shared hosting basis. Only the most popular Internet websites use a dedicated server for DNS hosting. The best type of DNS hosting is one that comes from a provider who has multiple servers in various geographic locations that minimize latency. Additionally, users can self-host their DNS servers by running special DNS software through generic Internet hosting services.

There are sites available where DNS hosting is free, used primarily for second level domains with registrars who do not offer free service or for third level domains. These free services can usually be upgraded to pay services in order to get more complex services for the websites. Free DNS service providers can earn money through sponsorships and the services are usually worldwide in order to provide high speed of work and reliability.
