Hello dear friends .
I had a question . I need a high internet speed to download and upload a series of files, and I read on a website that DNS can have a positive effect on the speed of the Internet and increase the speed of the Internet (download and upload speed), so I wanted to ask if What is the best DNS to increase upload speed… and how to change DNS in ubuntu 16.04?

[sAmI]

I'm not sure if its gonna increase your upload speed at all, In my opinion when i use DNS page works faster and loads way more quicker as before. I currently use Google DNS on my PC and Cloudflare WARP on my android devices, Some websites does not open up for me it gives DNS error so i use Google DNS and it works pretty much better and about ubuntu 16.04
You need to configure the /etc/network/interfaces
If you have two or more DNS add like this
dns-nameservers X.X.X.X Y.Y.Y.Y Z.Z.Z.Z

no DNS can increase upload and download speeds!
But for the best DNS is DNS brought by Cloudflare
They have better latency than Google's DNS

The best ever DNS is google DNS (8.8.8.8 and 8.8.4.4) and almost cover everything which are executed on internet. Google and openDNS attach you IP addresses to the DNS request This mean that the DATA is loaded from the server local to you. it will improve your overall internet speed.

Nonsense.

Nonsense, too.


A DNS server will never increase or decrease your overall Internet speed performance (down- or upstream). If you know what a DNS server does you will know why it will never increase or decrease the performance of your Internet connection.

For those who don't know here is a simple reminder: a DNS server looks up the IP address of a given domain and returns it to the client: google.com -> 123.123.123.123. This is needed because computer systems communicate over the IP protocol. We the humans however don't like to remember long IP addresses (e la IPv6 for example). So we use domains but our computers and servers still need the IP address to communicate. Hence why we use the DNS and DNS servers for domain to IP address resolution.

The correct and fast DNS server can however improve the overall usability and user experience while using the Internet. How/why? Well, a DNS server that is fast resolves domains to IP addresses quickly enough for us not to feel it. So to us it seems like the site is loading really fast because the DNS resolution time is really short. That however will never improve your ISP given Internet connection speed.

So what kind of DNS server would be right for you? A DNS server by a provider that knows their business and has servers all around the world offering anycast DNS servers. This means it will automatically use a DNS server to answer your DNS queries that is as close to you as possible to reduce DNS resolution timings. Such providers are CloudFlare and Google. Those are atleast the two biggest. There might be others.

I am agreed with you but my point of view is that good DNS server is a pioneer for smooth browsing.

Download via http like mega.nz website via DNS. Also, uploading via http, like picofile.com, is done through dns, and in these two sites, DNS plays an important role in downloading and uploading, and that's what I mean. Yes, I know download file with direct link is not related to DNS, but downloading with http as well as uploading with http is related to DNS, and DNS plays an important role in the speed of the Internet.
isn't it?
Am I wrong?

You don't upload anything via DNS to any site or service. DNS plays no role in terms of download or upload speed/performance. The only thing you "download" via DNS is the IP address that you are looking up via the DNS server. Although that is not anything we would consider download.

http/https is a protocol that works even without DNS/domains by simply using the server IP address. Example below.

HTTP site without a domain and thus without DNS resolution:

Code: (Select All)

http://86.83.113.141/ebooks/linux/

I see you didn't even bother to read my reply and the information about the domain name system and DNS servers. I see you are lacking some really basic knowledge and information about how the Internet works.

DNS doesn't affect your download nor your upload speed. All it matters for is how fast you get a IP address of a domain that you are trying to access. A fast DNS server will only improve how you feel the loading of websites but it will NOT AT ALL improve or make it worse how fast or slow you download or upload resources from or to a website. That kind of thing is based on a lot of factors such as bandwidth, available traffic, carriers, network load, server load and etc.

If only you read this thread well, and still think that DNS can speed up download / upload speed, please open your eyes to open Google and look for the keyword "What is the real function of DNS?" / "What is DNS? " / "How does DNS work? "
And try to experiment with downloading test files From slow sites with different DNS!
Will it affect your download speed?
Give the results in the next post!

@hamed To be honest. I'm actually glad you're not finding a high speed Internet for uploading files to your VPS. I'm crossing my fingers that the sponsor fire wall filters don't interpret the bulk uploading as "abuse".

I totally agree with the other members, but am also wondering whether possibly it's not DNS you're thinking about but caching.  Some DNS operators like Cloudflare use caching to speed up the downloading of files (provided you're close to a Cloudflare DNS Hotspot it may have the appearance of faster - if not close to a hotspot it may even be slower).  It doesn't have an effect on uploading though. And for the purpose that you have in mind it won't have any effect at all.
