what are dns servers?

Question

networking

Answer 1

they tell you computer where to find a web page...

For instance yahoo.com means nothing to a computer without a DNS server that tells it to go to an IP address such as 255.255.255.255

Essentially it is a phone book for computers.

Answer 2

The Answer is Quite Simple

Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4.

The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

The Domain Name Server resolves the name of the web site typed into the location field of the browser with the IP address of the server that will send the requested information from that web site. The DNS server is typically local in most major network environments and must be periodically updated to include new domain names and re-identify names and IP's that have changed. ...

The Domain Name System or DNS is a system that stores information about hostnames and domain names in a kind of distributed database on networks, such as the Internet. Most importantly, it provides a physical location (IP address) for each hostname, and lists the mail exchange servers accepting e-mail for each domain.

Answer 5

An address book for computers, that is networked by itself as well; because one machine couldn't possibly hold IP address lists of all active computers on the entire Internet, one Domain Name Service server may only contain the IP addresses for a select group of machines, so encountering a name of an unknown machine. It reads a part of the name and pass on the lookup to the next DNS server that would have better clue of the name; eventually the lookup will arrive to a DNS that has an entry of the IP address to that name, there you have the complete lookup. How DNS lookup is processed.

Answer 6

DNS stands for Domain Name System. A DNS server translates text names to the IP addresses that computers on the Internet communicate with.

For example a DNS server would convert answers.yahoo.com to an IP address such as 209.73.187.220

Answer 7

DNS servers are servers that host domain names. It's sort of a list of all the servers that are on the internet. The internet is really made up of servers with IP addresses (such as 66.94.234.13). While a computer can remember numbers without mixing them up, we would eventually. So, a DNS server associates 66.94.234.13 with the name YAHOO.COM. Instead of having to type 66.94.234.13, you just enter yahoo.com and the DNS servers translate that.

Answer 8

The Domain Name System (DNS) is a distributed internet directory service. DNS is used mostly to translate between domain names and IP addresses, and to control email delivery. Most internet services rely on DNS to work. If DNS fails or is too slow, web sites cannot be located and email delivery stalls. The servers those offer the service to translate between domain names and IP addresses are DNS servers.

Answer 10

DNS is short for Domain Name Server. It resolves the name of the website into the location field of the browser with the IP address. Domain names are alphabetical and because of this they are easier to remember. The internet is based on IP. With that in mind, an ip address like 188.88.8.162 can translate to www.website.com

Answer 11

EVERY computer on the internet and on private networks have an IP address. To remember one of the possible 4,162,314,256 possible addresses that a site like Google may have, the sites were given names like www.google.com.

a DNS server is a computer that looks up the name and returns the registered IP address to a TCP/IP application, like your browser. so when you type in http://www.google.com, the browser asks the DNS server Who is www.google.com and the DNS answers back, 64.233.161.147..........the browser then does an HTTP GET to 64.233.161.147.

I hope this helps
