#dns cache

[captain-acab]

I saw the post about using blokada to block tumblr live on Android, and then you mentioned blocking domains. How do I block domains?

When you install Blokada 5 and launch it, there should be four tabs at the bottom of the screen. The 2nd-left tab has a symbol of three vertical bars, and when you tap on it, says Activity. From here you can view all the domains your phone is trying to connect to. Any domain that you see in green, you can tap on to add it to the Blocked list.

If you launch Tumblr then go back to the Blokada Activity tab, you should see all the domains it's trying to connect to, including ones like "auth.gateway.tumblr-live.com" (yes, your phone connects to this whenever you launch Tumblr, even if you never open the Tumblr Live page). Tap those suckers and block them! (and if they scroll out of view too quickly, use the search 🔍 at the top of the screen to filter for "tumblr" and you should see them all again.)

Role of DNS in Internet Communication - Technology Org

Domain Name Systems (DNS) refer to hierarchical and decentralized naming systems for computers, services, and other internet-connected resources. A domain name is translated into an IP address used to communicate between devices. When a user enters a domain into their browser, the browser queries the DNS resolver provided by their ISP. Then, the DNS server converts URLs and domain names into IP addresses that computers understand and use. A user types into a browser and a machine interprets that as a command to find a webpage. This process of translation and lookup is called DNS resolution.

Now we understand what DNS is and how it works, we will talk about the role of DNS in Internet communication.

Visit Websites Quickly

Domain names allow people to access websites much easier than IP addresses. Instead of entering “69.63.176.13” into a web browser, a user can just enter “facebook.com.” The DNS server converts domain names into IP addresses. This enables users to access websites. 

Enable Internet connectivity

Internet communication relies heavily on DNS and IP. Without DNS, it would be difficult to remember all IP addresses for the websites we visit daily. DNS gives an easily recognizable domain name that can be used to visit websites. In contrast, IP is in the position of routing data packets between internet-connected devices. It ensures that data packets arrive at their target destination without being lost or damaged along the route. In order to find out what your public IP address is, What Is My IP can be used to check your public IP address, IP location, and your ISP.

Provides Internet Safety

In internet communications, DNS and IP security play an important role in ensuring internet safety. DNS attacks can route visitors to malicious websites, while IP spoofing allows hackers to impersonate devices and obtain unwanted network access. DNSSEC (DNS Security Extensions) and IPsec (IP Security) are two technologies that protect DNS and IP respectively and thus secure communications.

Monitor Network Traffic

DNS and IP are critical components for controlling internet network traffic. DNS servers cache commonly requested domain names to reduce the load on the DNS system and improve response times. On the other hand, IP uses various routing protocols, including OSPF and BGP, to control network traffic and guarantee that data packets are effectively delivered between internet devices.

How to clear dns cache from your pc or laptop

If you're experiencing "Error Code 102630: This video file cannot be played" on Firefox

i've been scratching my head about it for weeks and just solved the issue today - it might not work for you, but i'm posting it here in case it helps someone else.

things i tried that didn't work (but might help you):

updating/restarting firefox

updating/restarting windows (or your operative system of choice)

manually updating the video drivers

deleting the DNS cache

deleting the browser cache

running Firefox in troubleshooting mode (no extensions or add-ons) to make sure it wasn't some extension that broke in an update

what actually worked for me:

go to about:config (open a new tab and use that in place of the URL)

look up "media.mediasource.enabled"

if it's set to "false", set it back to "true" by double-clicking it

i had this configuration set to false in order to get videos to buffer completely instead of just loading a couple minutes at a time and then stopping, but unfortunately this does not seem to play well with most streaming sites/servers. pretty sure it worked well before, but an update must have broken it.

ah, well.

Site Update II

Been fighting for my life on site issues over the past two weeks. Thankfully, my hosting provider does give me help, but DNS records, propagation times, reverting failed changes, activation errors, and caching have become my nightmares.

My apologies for the downtime regardless. I'm aware that I don't owe the site to people, it's a free resource, yadda yadda, however this was a case of trying something too far outside of my wheelhouse. Lesson learned (just not in Commander).

Once things are fully back to normal, with plenty of testing, the Summer Mega Update will be shared.

TARI.EXE (Puzzlevision Corruption)

I'm not even kidding, I had a dream where that TV guy and Tari have some sort of connection and kidnapped her so she becomes his property again, forcing the SMG4 gang to go through endless unwanted simulations to entertain him. I've been thinking about that dream repeatedly, and ever since Western Spaghetti I did want there to be some sort of connection. Can't wait to see more of TV Guy (or Puzzlevision as it says on his face). Also, the background text are just command prompt text, or rather Tari's programming. I've been finding so many examples of how to do program writing.... or coding? Idk lol. At some point my brain just stopped working. Anyways, i'll put below what the text says, and if you pay attention to the numbers in the written sequence, you'll see some hidden detail (Hint: The numbers are episode dates).

Got 100 out of 100, on both Ad blocking testing sites.

With Ublock Origin Settings (recommended Ublock Origin n other add-on Setup*) and Easy way setup DNS on both Firefox & Floorp Browser.

Adblock Testing Sites (they imperfect, but still work for test many setups):

adblock-tester.com

d3ward.github.io/toolz/adblock.html

*(There only 2 reccommend extensions, and 3 with approved checkmarks. Less is better, don't add all. And a whole category for "Don't Bother", would reccommend take those extensions off if still have installed.)

Screenshots of 100 score:

Cleared cache on both n here are results.

First Test Site.

Second Test Site.

Would you like to tell us more about how the pi-hole network thing works? I'm very curious! If not that's okay too

Pi-hole blocks ads and trackers on your home network. It works by acting as the DNS server for your devices.

A DNS server is like a phone book. It translates URLs to IP. For example, when you type tumblr.com the computer doesn’t know where to go, so your DNS server will find what IP belongs to tumblr.com and sends you the IP address. This doesn't take very long, but if you’ve ever noticed that it’s slower to connect to a new website the first time, this is why. Then this will usually be cached on your device so that you can connect faster the next time. 

So Pi-hole will block whatever URLs/IPs you tell it to on any device connected to your network. 

Though keep in mind it can’t block everything on certain websites. For example: youtube ads. This is because youtube ads come from the same source as the video, so if you were to try to block the ad you’d just be blocking the video as well. Ad blockers on your browser work differently so they are able to block youtube ads.

To actually set this up you need a home server, a raspberry pi/similar device, or a laptop/pc that will be running 24/7. Regular consumer grade tech isn’t designed to run constantly like a server is, so it’s more likely to fail.  Most often people use the raspberry pi or something similar because it's small, low power, and it’s cheap. 

I’m not going to actually go in depth step by step on the install process here as there are guides online, but it's not difficult. Though it does require installing linux, using the command line, and accessing your router settings. This is probably intimidating to most people, but you really can just follow a guide online and once it’s set up you can access it remotely through your browser.

Though if you have a comcast router like me, you will not be able to set the pi-hole as a dns server. Instead you will just assign it a static IP and manually set it as the DNS server for any devices that you want it working on. This means if someone comes to your house and connects to the wifi, they will not have their connection running through the pi-hole automatically, it must be done manually on the phone.
