What is a dns servers and google DNS server ip and more about Google DNS server not Responding with you,  The Domain Name System is a standard innovation for overseeing open names of Web destinations and other Internet areas.

Domain Name System innovation permits you to sort names into your Web program like compnetworking about com and your PC to naturally find that address on the Internet.

Google DNS server not Responding

What is a dns server and Google DNS server not Responding IP Fix all

A key component of the Domain Name System is an overall accumulation of DNS server. A DNS server is any PC enrolled to join the Domain Name System. A DNS server runs unique reason organizing programming; components like an open IP address, and contain a database of system names and addresses for other Internet has.

DNS Root Servers

DNS server correspond with one another using private system conventions. All DNS server are sorted out in a chain of command. At the top level of the progression, supposed root servers store a complete database of Internet area names and their comparing IP addresses.

The Internet uses 13 root servers that have turned out to be fairly well known for their exceptional part. Kept up by different free offices, the servers are suitably named A, B, C thus on up to M. Ten of these servers live in the United States, one in Japan, UK and one in Stockholm, one in London, and Sweden.

How DNS Works

The Domain Name System is a spread framework, implying that just the 13 root servers contain the complete database of names and addresses. All different DNS servers are introduced at lower levels of the chain of importance and keep up just certain bits of the general database.

Most lower level DNS server are claimed by organizations or Internet Service Providers (ISPs). For instance, Google keeps up different DNS server around the globe that deal with the google.com, google.co.uk, and different spaces. Your ISP likewise keeps up DNS server as a feature of your Internet association setup.

At the point when a DNS server gets a solicitation not in its database, (for example, a topographically inaccessible or once in a while went to Web webpage), it briefly changes from a server to a Domain Name System customer.

The server naturally passes that demand to another DNS server or up to the following more elevated amount in the Domain Name System chain of command as required.

In the long run the solicitation touches base at a server that has the coordinating name and IP address in its database, and the reaction streams back through the chain of DNS server to your customer.

Design your system settings to Use Google Public DNS

When you are making use of Google Public Domain Name System, you are changing your Domain Name System “switchboard” administrator from your ISP to Google Public Domain Name System.

As a rule, the IP locations utilized by your ISP’s space name servers are consequently set by your ISP by means of the Dynamic Host Configuration Protocol (DHCP).

To use Google Public Domain Name System, you have to unequivocally change the Domain Name System settings in your working framework or gadget to utilize the Google Public Domain Name System IP addresses.

The method for changing your Domain Name System settings shifts as indicated by working framework and form (Windows, Mac or Linux) or the gadget (PC, telephone, or switch).

Before you change your Domain Name System settings to use Google Public Domain Name System, make sure to record the present servers locations or settings on a bit of paper. It is critical that you keep these numbers for reinforcement purposes, If you have to return to them whenever.

Google Public DNS IP addresses

The Google DNS IP addresses (IPv4) are as per the following:

8.8.8.8

8.8.4.4

The Google Public DNS IPv6 locations are as per the following:

2001:4860:4860::8888

2001:4860:4860::8844

You can make use of either address as your essential or optional DNS server. You can indicate both locations, yet don’t determine one location as both essential and optional.

You can design Google Public DNS IP addresses for either IPv4 or IPv6 associations, or both.

How to Test Google DNS Server

· Open your command prompt and clear your Domain Name System cache

· After that use the command ipconfig /flushdns.

· Then do a nslookup for any web address and you should see 1e100.net with 8.8.8.8 as the IP address for the Domain Name System resolver.

Google DNS

Google DNS for quicker execution. If you are situated outside the US — like I am and like most APC perusers are — this is an awful thought. I just found why subsequent to encountering moderate download speeds for a while.

Like other tech devotees I bounced on the chance to switch my PC’s space name server settings far from my ISP’s defaults to — I accepted — the much bigger and speedier Google DNS server at 8.8.8.8 and 8.8.4.4 when they were initially declared.

In case you’re not acquainted with what exactly DNS server do they decipher the web address you write into your program into the real IP location of the web servers you’re interfacing with at the flip side.

For instance a DNS server will change over “apcmag.com” wrote into your program location bar into “125.7.5.1” which is the IP location of our server at Macquarie Telecom’s datacentre.

DNS server can be one reason (among numerous) of slowness in your web browsing if your ISP’s DNS server is over-burden and reacting slowly — you may encounter a deferral of seconds every time you go to a web address that your PC hasn’t seen as of late (and in this manner needs to interface with a DNS server to figure out the associating IP address).

This is one of the issues that outsider open DNS suppliers like Google DNS and OpenDNS should fix — quicker more reliable Google Lookups.

Google Public DNS Server

Google being Google, they have gigantic scale, burden adjusting, excess and DNS server conveyed everywhere throughout the world. They likewise support the most recent advancements and security components like IPv6 DNS server and DNSSEC. Their DNS server are likewise all around secured against DoS attacks and cache poisoning attacks.

It’s important that Google Public Domain Name System does not perform any blocking or sifting on the DNS asks for, as a percentage of alternate administrations do. They express that just under exceptional circumstances would they square anything.

For me, this is a decent choice in light of the fact that I utilize different apparatuses to sift through malware destinations, and so on and don’t as a matter of course need my DNS administration to be included.

The principle advantage for using Google is their worldwide server farm and the way that they have DNS server situated far and wide. Some different administrations just have DNS server situated in one piece of the world, so the execution will endure significantly.

The primary drawback to using Google is that they are about following and logging all that anybody does on the Internet and this is no special case.

Google DNS Servers

Google.com DNS Servers

Name Server IP Location

ns1.google.com 216.239.32.10 Mountain View, CA, US

ns2.google.com 216.239.34.10 Mountain View, CA, US

ns3.google.com 216.239.36.10 Mountain View, CA, US

ns4.google.com 216.239.38.10 Mountain View, CA, US

Google DNS IP

Like OpenDNS, Google today propelled their own open DNS administration that they say will make your web-surfing background “speedier, more secure and more solid.”

In the event that you need to get to a webpage (say example.com) from your program, your PC needs the IP location of the web server that is facilitating that area. The PC will then inquiry an open DNS server to discover the IP location of the site example.com.

This DNS server is for the most part kept up by your ISP yet now you can train your PC (or remote switch) to use Google’s DNS server rather than your ISP’s DNS server. Google says their Public DNS Server are facilitated in server farms around the world, and they utilize anycast directing to send clients to the geologically nearest server farm.

Select Internet Protocol(IP) Version 4 (TCP/IPv4) – Google DNS IP trailed by Properties and them supplant the IP locations of your Preferred DNS server and Alternate DNS server with the IP locations of the Google DNS server which are 8.8.8.8 and 8.8.4.4 – the request doesn’t make a difference.

If you might want to setup Google DNS at the switch level, open your switch dashboard (e.g., http://192.168.1.1) and put the Google DNS server IP addresses (8.8.8.8 and 8.8.4.4) as your DNS server settings and apply.

DNS Lookup: How a Domain Name is Translated to an IP Address

Domain Name System is the thing that interprets your commonplace area name (www.google.com) into an IP address your program can use(173.194.33.174). This framework is crucial to the execution of your site page, yet a great many people don’t completely see how it functions.

Along these lines, keeping in mind the end goal to offer you some assistance with bettering comprehend the accessibility and execution of your webpage, we will be distributed a progression of online journal articles to reveal insight into the occasionally complex universe of Domain Name System, beginning with the basics.

For the purpose of straightforwardness, this article is accepting there was no Domain Name System reserved anyplace, henceforth this is a most dire outcome imaginable.

The DNS must be determined so the program can build up a TCP association with make the HTTP request. Also, for each outside asset referenced by a URL, the Domain Name System determination must finish the same steps before the solicitation is made over HTTP.

The Domain NameSystem Resolution procedure begins when the client sorts a URL address on the program and hits Enter. As of right now, the program approaches the working framework for a particular page, for this situation google.com.

Step 1: OS Recursive Query to DNS Resolver

Since the working framework doesn’t know where “www.google.com” is, it inquiries a Domain Name System resolver. The question the OS sends to the DNS Resolver has an uncommon banner that lets it know is a “recursive inquiry.” This implies the resolver must finish the recursion and the reaction must be either an IP address or an error.

For most clients, their DNS resolver is given by their Internet Service Provider (ISP), or they are using an open source option, for example, Google DNS (8.8.8.8) or OpenDNS (208.67.222.222). This can be seen or changed in your system or switch settings. As of right now, the resolver experiences a procedure called recursion to change over the space name into an IP address.

Step 2: DNS Resolver Iterative Query to the Root Server

The resolver begins by questioning one of the root DNS server for the IP of “www.google.com.” This inquiry does not have the recursive banner and hence is an “iterative inquiry,” which means its reaction must be a location, the area of a definitive name server, or a blunder.

The root is spoken to in the concealed trailing “.” toward the end of the space name. Writing this additional “.” is redundant as your program consequently includes it.

There are 13 root server bunches named A-M with servers in more than 380 areas. They are overseen by 12 unique associations that answer to the Internet Assigned Numbers Authority

Step 3: Root Server Response

These root servers hold the areas of the greater part of the top level spaces (TLDs, for example, .com, .de, .io, and more current non specific TLDs, for example, .camera.

The root doesn’t have the IP information for “www.google.com,” yet it realizes that .com may know, so it gives back the area of the .com servers. The root reacts with a rundown of the 13 areas of the .com gTLD servers, recorded as NS or “name server” records.

Step 4: Domain Name System Resolver Iterative Query to the TLD Server

Next the resolver inquiries one of the .com name servers for the area of google.com. Like the Root Servers, each of the TLDs have 4-13 bunched name servers existing in numerous areas.

There are two sorts of TLDs: nation codes (ccTLDs) keep running by government associations, and bland (gTLDs). Each gTLD has an alternate business element in charge of running these servers. For this situation, we will be utilizing the gTLD servers controlled by Verisign, who run the .com, .net, .edu, and .gov among gTLDs.

Step 5: TLD Server Response

Each TLD server holds a rundown of the majority of the definitive name servers for every area in the TLD. For instance, each of the 13 .com gTLD servers has a rundown with the greater part of the name servers for each and every .com area.

The .com gTLD server does not have the IP addresses for google.com, but rather it knows the area of google.com’s name servers. The .com gTLD server reacts with a rundown of the greater part of google.com’s NS records. For this situation Google has four name servers, “ns1.google.com” to “ns4.google.com.”

Step 6: Domain Name System Resolver Iterative Query to the Google.com NS

At last, the DNS resolver inquiries one of Google’s name server for the IP of “www.google.com.”

Step 7: Google.com NS Response

This time the questioned Name Server knows the IPs and reacts with An or AAAA location record (contingent upon the inquiry sort) for IPv4 and IPv6, individually.

Step 8: DNS Resolver Response to OS

As of right now the resolver has completed the recursion prepare and can react to the end client’s working framework with an IP address.
