DNS hosting and security are generally not thought of together, but what happens when your name servers are unavailable for some reason? What if your domain gets misconfigured? Traffic redirected? Don't let these things happen to you.

Caltechsys has security at its core, Our DNS and mail services are built and operated with security as a priority, and we're dedicated to the security of every domain we service. Some questions to ask when looking for a DNS services provider.

 

Why is DNS important ?

Think of DNS as a kind of phone book for the Internet. If you have a person's name, but do not know their telephone number, you can look it up in a phone book. DNS provides this same type of service to the Internet. When you visit 'http://www.google.com' in a web browser, DNS retrieves the site's IP address, '72.14.207.99', which the browser then uses to connect to the webserver.

Without phone books, you would not be able to learn someone's telephone number unless they previously gave it to you. Likewise, without DNS, you would only be able to reach sites via their IP addresses; instead of 'www.google.com' or 'www.google.com', you would have to type  'http://72.14.207.99' every time you wanted to view the sites.
