Maybe a dumb question, but I'm a noob.<br />
<br />
We are moving colocation facilities - we currently just have ns1.ourdomain.com - when this server is moved to another address, how is DNS going to update. How is the world going to know anything,ourdomain.com when ns1,ourdomain.com is the authoratative (and only) DNS server for our &nbsp;small domain and it changes IP addresses. To me its a chicken / egg problem. How can it resolve <a href="http://www.ourdomain.com" rel="ugc">www.ourdomain.com</a>&nbsp;if it can't find ns1.ebby.com? Do I need to do anything or will BIND start talking to the world with its new IP address?

DNS Server

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
