Dns

Hello,

DNS is critical to the operation of the Internet. When you enter www.some-domain.com in a Web browser, it's DNS that takes the www host name and translates it to an IP address. Without DNS, you could be connected to the Internet just fine, but you ain't goin' no where. Not unless you keep a record of the IP addresses of all of the resources you access on the Internet and use those instead of host/domain names.

So when you visit a Web site, you are actually doing so using the site's IP address even though you specified a host and domain name in the URL. In the background your computer quickly queried a DNS server to get the IP address that corresponds to the Web site's server and domain names. Now you know why you have to specify one or two DNS server IP addresses in the TCP/IP configuration on your desktop PC (in the resolv.conf file on a Linux system and the TCP/IP properties in the Network Control Panel on Windows systems).

A "cannot connect" error doesn't necessarily indicate there isn't a connection to the destination server. There may very well be. The error may indicate a failure in "resolving" the domain name to an IP address. I use the open source Firefox Web browser on Windows systems because the status bar gives more informational messages like "Resolving host", "Connecting to", and "Transferring data" rather than just the generic "Opening page" with IE. (It also seems to render pages faster than IE.)

Hope this helps.

The total ip addresses are hidden to view in DNS services, And how to know the domain ip address ?

DNS stands for Domain Name Server, and is the system used to translate word-based addresses of systems to the numerical IP (Internet Protocol) address of the computer or system that should be located at that address.

Hi,

To be able to know the domain ip address lets use nsloookup on command line windows.
Here is the output of :

C:\Users\users3>nslookup us.gmocloud.com
Server: resolver2.opendns.com
Address: 208.67.220.220

Non-authoritative answer:
Name: us.gmocloud.com
Address: 8.30.161.17


C:\Users\user>nslookup www.us.gmocloud.com
Server: resolver2.opendns.com
Address: 208.67.220.220

Non-authoritative answer:
Name: www.us.gmocloud.com
Address: 67.215.65.132

Similarly you can convert any other domain name into its IP address. You can also check the result by typing the IP address in the browser address bar.
Now, for the more tech savvy folks the nslookup command is used for testing out DNS servers.

Hope this helps.

The Domain Name System (DNS) is a focal piece of the Internet, giving an approach to coordinate names (a site you're chasing) to numbers (the address for the site). Anything associated with the Internet - portable workstations, tablets, cell phones, sites - has an Internet Protocol (IP) address made up of numbers.

The full form of DNS is Domain Name System which is the Internet's equivalent of a phone book.It translates Internet domain and host names to IP addresses and vice versa.Larger corporations also use DNS to manage their own company intranet.

The Internet's system for converting alphabetic names into numeric IP addresses. For example, when a Web address (URL) is typed into a browser, DNS servers return the IP address of the Web server associated with that name.

Each system have a different DNS for their Computer.

DNS stands for “Domain Name System”. It's a system that lets you connect to websites by matching human-readable domain names (like wpbeginner.com) with the unique ID of the server where a website is stored. Think of the DNS system as the internet's phonebook.
