Domain Name System

Domain Name System

The Internet and many networks IP (Internet Protocol), the largest and depends on the domain name system (DNS), to help direct traffic. Managing a distributed network database DNS addresses Namis and, provides methods for remote computer to query the database. Some call it DNS "phone book for the Internet."

DNS and the World Wide Web

Runs all public Web sites on a server connected to the Internet via public IP addresses. And Internet uses DNS service name resolution for websites worldwide. If someone writes the name of the Web page in the browser,

it seems the DNS for the corresponding IP address for this Web site, data is essential to the required network connections between a Web browser and Web server that is running.

DNS configuration networks

You must have a DNS client (called a resolver), which would use the DNS configuration of your network. Solving that uses a DNS query to the fixed (static) IP addresses of one or more DNS servers. To configure a router DNS server

 addresses Abrwadb and on a home network and automatically get the clients, or you can configure the addresses for each customer. Home network administrators can get a valid DNS server addresses from your Internet service provider or a third party DNS provider such as Google public DNS and Open DNS.

DNS server hierarchy

Use the DNS client/server Nitoorkarchitiktori. Are the computers that are intended to save the database (names and addresses), DNS records and DNS clients, mobile phones and other devices for end users include DNS servers.

Hey, Charles Henson is here. Today I'll show you how to Setup Google DNS on your router. Maybe this will do and why DNS is working like a phone book with Google DNS, we are able to, directly to the source to find the target for what you are looking for. So you want to open Internet Explorer or Safari, and you want to connect to your router. Transferred once logged into the router, you will need to manually configure and click your Internet connection. We want to go and perform the manual for connecting to the Internet, and here we have two options for primary and secondary DNS services. Google is the primary DNS server and secondary DNS are Google, 8.8.4.4 8.8.8.8 and then want, In addition to the settings here, and you want to restart your router. That is why we are now Google as our DNA right in the heart of Google. So will accelerate to surf, we have, of course, because we know that we have a response from the DNS server returns, we provided first and foremost.

Types of DNS

DNS IP addresses automatically is to convert the most used Web browsers Internet domain names. In addition, it is also used to view progress DNS:

• Find the right email delivery servers on the Internet.

• Reverse lookups to convert IP address to domain name

Network requests DNS lookup functions in TCP and UDP port 53 runs by default.

Dynamic DNS

Require DNS that is stored in a constant database will record all IP address information. This is suitable for standard websites, but not for devices with dynamic IP addresses, such as cameras in the home network or Internet Web servers. Adds dynamic DNS (DDNS) extensions to enable the network protocol for DNS name resolution as a service for customers dynamic.

Various manufacturers of dynamic DNS packages are for those wanting remote access with your private network over the Internet. Setup requires "on your local network to install a signature dance at the Internet service provider you have selected, and additional software. DDNS provider monitors subscribed devices and make the necessary updates to DNS name server.

DNS cache

The best treatment for large amounts of applications, uses the DNS cache. DNS cache local copies of the store that was accessed recently, while the specified servers to maintain the original records. To avoid, through

DNS server hierarchy to generate network traffic for local copies of DNS records. However, if a DNS cache outdated network connection problems can result. DNS caches also were vulnerable to attacks from hackers network. Network administrators to disable the DNS cache, possible using the command "Ip config", and similar installations.

Google's DNS setting on a router is something I could do, directly to the source file directly to change the information. Google DNS setting on the router with the help of technology and the expert cloud strategy of small and medium-sized enterprises in this free video clip.
