The best Dynamic DNS providers

The concept of serving outsiders from an IP address that is not fixed is relatively new. Therefore, this is a market in which new entrants can easily make an impression. However, without relying on highly-respected brand names, it is time-consuming working out which dynamic DNS service is going to be reputable.

Our methodology for selecting a dynamic DNS solution for your business

We reviewed the market for dynamic DNS systems and analyzed services based on the following criteria:

  • A service that masks the real IP address of your servers
  • Alternatively, a DNS updater that is fast enough to keep up with addressing changes on your network
  • Support for email server addressing
  • A reliable service with constant availability
  • IPv6 support
  • A free system or a free trial to enable access to the service for assessment without any payment
  • A good deal from a free tool that won’t let you down or a paid tool that is worth the money

With these selection criteria in mind, we looked for dynamic DNS providers that will keep your Web services available to the public. Competence and availability are bigger issues than price. Although free services are always nice, they cost you money if they block your opportunity to make sales. So, where we include free options, they are very good services that compete well with the paid systems.
