Internet Hosting Services
An Internet hosting service is a service that runs Internet servers and allows organizations and individuals to serve content to the Internet. There are various kinds of services offered.
A common kind of hosting is Web hosting. Most hosting providers offer a fusion of services such as email hosting. DNS hosting service is usually grouped with domain name registration.
Email Hosting Service
An email hosting is an Internet hosting service that operates email servers. Email hosting services typically offer premium email at a cost as opposed to advertisement-supported free email. Email hosting services thus vary from typical end-user email providers such as webmail sites.
Hosting providers can manage a user’s own domain name, along with email authentication scheme that the domain owner wishes to enforce in order to convey the meaning that using a specific domain name identifies and qualifies email senders.
Most email hosting providers offer advanced premium email solutions hosted on dedicated custom email platforms. The offerings of different email hosting providers can therefore vary with different needs. Almost all webhosting providers offer standard email hosting.
DNS Hosting Service
A DNS hosting service is a service that runs Domain Name System servers. Most domain name registrars include DNS hosting service with registration. Many third-party DNS hosting services provide Dynamic DNS. 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. By operating DNS nodes closer to end users, DNS queries travel a much shorter distance, thus resulting in faster Web address resolution speed.
DNS can be self-hosted by running DNS software on generic Internet hosting services.
A number of sites offer free DNS hosting, either for second level domains registered with registrars or as third level domains. These services generally also offer Dynamic DNS. In many cases the free services can be upgraded with various premium services.
Free DNS service providers can also make money by sponsorship. The majority of modern free DNS services are sponsored by large providers of telecommunication services.
