Is google dns real safe? no answer from google

[jraju]

Hi, i changed my ISP service provider dns to public google dns, as avast prompted some network vulnerabilities.
But , after changing to google.dns, a scan at dnsleak.com, found a server in malaysia accessing my network connection. I also noticed some popup from that server in malaysia.
i wrote to google forum, which did not evince any reply.
i wrote in some other forums but could not get a satisfying reply.
I also read forum topics here, which suggest switching to public dns,if we come across internet access loss or any dns inherent problems.
Either the trace could be my ISP servers or Google servers in my networking connections. What a malaysian server , not at all connected would be doing , i.e accessing my network or router?
It was almost nov 4,2017, when i did the dnsleak com test. But still puzzled by this behaviour of google, giving access to unknown service to the users .
The curse is if i use firefox also, the search engine is google .
Is google giving access to web servers for advertisement or other purpose
i really rate dnsleak.com test as perfect.
Normally one would not check those things, if one has internet access
i changed to my ISP immediately for safety purpose, as any query could be easily answered to my ISp, thro which i am getting internet connection. Any idea
After switching to my ISP, the dnsleaktest com does not produce so many servers as before

There is a new fast DNS 1.1.1.1 the leak basically means a server has done a DNS lookup on your PC possibly when you connected to their server this is often done to give you related content Netflix who won't supply some services if your not in USA

Google will read the IP you are using, Google will read the ISP you are looking at, Google will serve adverts to the IP you are using in the page you are reading

This is the way that google works and makes their vast fortune - They do not care who you are. If you are looking at a gardening page they will serve adverts about gardening If you are looking at a page showing holidays they will serve holiday ads and maybe cheap airline fares. The reason they do this is to sell products for their customers that Pay Google for this service. Without this link provided by google you would still get adverts, but they would be for random items that would probably not interest you.

Your ISP will also take the same information about what sites you visit from their DNS, the difference is that they will sell your information to anyone with the money to pay, and of course the ISP knows who you are and where you live so can sell postal information as well as the IP Data. Most people change their IP address regularly but their name and postal address a lot less often

the new Cloudflare 1.1.1.1 DNS does things a little differently Cloudflare are one of the major Internet Network infrastructure suppliers on the planet so they have an interest in better quality data transfer through theitr naetworks and the rest of the Internet so have worked with the people who issue IP Numbers to provide a service that is quicker, private and more reliable that the others ( they claim, and my experience so far agrees with this)

Hi, thanks for the reply. The fact that i do notice is that while adverts and all related stuff is one thing, the allowing of a dns server, as actual dns server at a time of browsing is puzzling me. Why do google do this? Already face book leaks are doing round the corner.
Elsewhere in some of the threads, i do come across the recommendations of using public dns, especially google 8.8.8.8. The peculiar thing i noticed that this is always not allowed, but at times , say odd hours, or dull hours of the day.
when i switched back to my ISP, the dnsleak.com test only show one server of my ISP as my actual dns server.
There is a beta version of router check beta for pc, that list the actual dns servers besides scanning for vulnerabilities in the routerset up.
Now google ask you to do a survey of your standing place, to gather more local nature and data of the users.

DNS is best provided by a network of servers, this means that if a server fails then you retain service. This is the way the Internet is designed to work, The original concept taken from the Military Communications system designed to re-route messages if a particular location was Taken out.

One of the problems with small ISPs , (and even some large ones ), is that the only run one or a small number of DNS servers, this means that they can get swamped and fail to work properly and at best most are slow

Google provides this service as it helps them collect more data as I mentioned above, they can also afford to use multiple servers which gives speed and reliability.

There is also Open DNS which allows you to block some types of site

Cloudflare are a large organisation who own and run a huge number of servers anyway they are simply making these available to private users for free
