Top 3 DNS Providers That Provides Good Service in SEA (Southeast Asia)

If you give a hacker a new toy, the first thing he’ll do is take it apart to figure out how it works.

— Jamie Zawinski.

DNS or Domain Name System sometimes called the phonebook of the internet is one way for us to easily access our favorite website, it translates and redirect human readable domain names (e.g. yahoo.com, google.com) to their respective IP address. Finding the good DNS provider is vital in accessing information that is sometimes censored by our government, ISP and the likes. This are my top three good DNS (Domain Name System) providers that are really fast, secure and reliable that can be use in Southeast Asia.

Cloudflare

Cloudflare Public DNS (IPv4)

1.1.1.1
1.0.0.1

Cloudflare Public DNS (IPv6)

2606:4700:4700::1111
2606:4700:4700::1001

So why Cloudflare1? Choose Cloudflare if you want less than <1ms of domain name resolution. Seriously, they have the fastest name resolution on the internet.

Google

Google Public DNS (IPv4)

8.8.8.8
8.8.4.4

Google Public DNS (IPv6)

2001:4860:4860::8888
2001:4860:4860::8844

So why Google2? You will use this if you need an old but still good reliable DNS server. Its been used as a primary name resolution on big companies as well as local workstation. Its much more better than your ISP (Internet Service Provider) provided DNS.

Yandex

Yandex DNS (IPv4)

77.88.8.8
77.88.8.1

Yandex DNS (IPv6)

2a02:6b8::feed:0ff
2a02:6b8:0:1::feed:0ff

So why Yandex3? You’ll choose this if you’re a webmaster due to super fast name resolution propagation. This is the fastest DNS for name resolution propagation, on which ever region you are currently.

These three are mostly corporate but they do provide fast speed TLD name resolution. And if you really still feel they can be manipulated, feel free to enable DNSSEC. For example on CloudFlare, a single domain would resolve at less than <1ms.

So guys, what are your top DNS providers?

Disable mDNS and SSDP Discovery in Google Chrome

We’re born alone, we live alone, we die alone. Only through our love and friendship can we create the illusion for the moment that we’re not alone.

— Orson Welles.

If you ever check your task manager you’ll notice chrome is listening to port 5353 on Linux. Did you know you could stop it? as what this sub-process is specifically doing – listening and doing some device probing like an auto discovery which is similar to avahi. In order to disable this Chrome functionality you need to first create a directory and policy file. You could do this by executing the command below.

sudo mkdir -p /etc/opt/chrome/policies/managed/
sudo touch /etc/opt/chrome/policies/managed/block_mdns_ssdp.json

What this does is first create a directory inside the /etc/opt/chrome which will be used to store manage policies and create the initial policy file that we would be editing.

Then we edit the block_mdns_ssdp.json file that we created earlier and then we put the contents below.

{
	"EnableMediaRouter": false
}

This would specifically disable media router and probing of cloud printers utilized by Chrome.

NOTE: Don’t disable this functionality if you use cloud printers.

So to conclude there are some hidden sub process/services Chrome is running under the hood to manage specific Chrome functionality. So guys, what functionality or sub-process you want to disable inside Chrome? Let me know and as always live life and hope you enjoyed this article!

Disable Snap Daemon in Archlinux

Carry out a random act of kindness, with no expectation of reward, safe in the knowledge that one day someone might do the same for you.

— Princess Diana.

One day I woke up and I just don’t want to use Snap apps anymore. So how do I remove it from my workstation? Here are the things I’ve did to completely removed it from my workstation.

In order to disable Snap apps on your workstation you must first list all snap services and the included PID (Process Identifier) sockets running.

systemctl list-unit-files | grep snap

After you listed all of it, you must disable all known snap services. Below is just a gist of running snap services on my workstation (on Fedora Linux).

sudo systemctl disable snapd.service  
sudo systemctl disable snapd.seeded.service  
sudo systemctl disable snapd.socket  
sudo systemctl disable var-lib-snapd-snap-core-6130.mount

After you completed the steps above you must then restart your workstation for a much more cleaner startup.

So guys, if you have any problem running the above command let me know? That’s it guys as always live life and hope you enjoyed this article!
