Tip of the Week DNS What is DNS (Domain Naming System)? Think of it as a phone book for the Internet. Everything attached to the Internet has an IP Address. This address is unique between all devices on the Internet and is used so that it can be located just like your home address. DNS is used to associate a name to the IP address. As an example, you could go to 97.74.214.44 and get to our web page. Instead of trying to remember that number you type in the URL name of oneupt (easier to remember). When you type in a name, your computer first will look to see if it has a local record (cached) for the name. If it doesn’t have it cached, it will then query your Internet Service Providers DNS. The DNS record will then direct your computer to go to the IP address listed for that name. Within a company network the DNS server could be stored locally so that each of the computers would know how to browse the network. Your mail server listed as mail.mycompany.local might have a record of 192.168.1.5. If the DNS server for the local network is not functioning correctly it could cause the workstations the inability to connect to the mail server or even the company network. That is DNS in a nutshell. If you have any questions or believe that your company is experiencing any DNS issues, please feel free to contact us.
