It is difficult for public Internet resources to know how to find a webserver or mailserver or other Internet-addressable resource located at a dynamic IP address.DDNS provides a workaround, giving an individual a method of registering their current IP address with a third-party service on the web so they are publicly accessible and addressable, even as their IP address changes over time.

Specifies authoritative information about a DNS zone, including the primary name server, the email of the domain administrator, the domain serial number, and several timers relating to refreshing the zone Here's how it works: When an authoritative DNS provider suffers an outage, all of the Websites it provides service for are taken offline. So effectively Umbrella users will be able to access websites that appear down for everyone else.

For our millions of users at businesses, schools, and libraries around the world, this saves them from Internet access interruptions.
