Domain Name System (or Service),
an Internet service that translates domain names to or from IP addresses,
which are the actual basis of addresses on the Internet. The Domain Name System (abbreviated DNS) is an Internet directory service. DNS is how domain names are translated into IP addresses, and DNS also controls email delivery. If your computer cannot access DNS, your web browser will not be able to find web sites, and you will not be able to receive or send email. The DNS system consists of three components: DNS data (called resource records), servers (called name servers), and Internet protocols for fetching data from the servers. The billions of resource records in the DNS are split into millions of files called zones. Zones are kept on authoritative servers distributed all over the Internet, which answer queries based on the resource records stored in the zones they have copies of. Caching servers ask other servers for information and cache any replies. Most name servers are authoritative for some zones and perform a caching function for all other DNS information. Large name servers are often authoritative for tens of thousands of zones, but most name servers are authoritative for just a few zones. Stands for Domain Name System. This is a system that using a database, translates your IP address or Internet Protocol address into an easy to remember name such as, www.monstercommerce.com. So essentially, it makes it to where you don't have to remember a long series of numbers, but rather an actual name of a place. The DNS server's main job is to bind the IP address to a domain name. It can also be referred to as a name server, or domain name server. Whether you are using ftp, gopher, or http (web) these all require IP addresses. |

The Public DNS Service is a public
service provided by Granite Canyon Group, LLC. The Service offers both
primary and secondary DNS free of charge to anyone who asks. The Service
maintains UPS protected FreeBSD servers that satisfy DNS queries. The
servers are geographically separated and all are connected to the Internet
via 7x24 dedicated lines with disjoint routes to the Internet's North
American backbones. The Public DNS is useful if you: Can't get free service from an ISP and don't want to do it yourself Need secondary DNS servers Need MX records for a virtual domain Want control over your DNS records: change DNS frequently, changing ISPs soon Are inside of a firewall and need publicly-accessible name servers outside of your firewall Need name servers that are closer to the North American Internet backbones |
