Dns Blocking 4 noobs: How ISPs block websites
Вставка
- Опубліковано 7 лют 2025
- A very very basic approach to how DNS requests work, and how ISPs may block websites (just one of the ways) if they wish.
I plan on making another video going into the technical aspect of how DNS works, inspecting the actual requests and packets and a detailed explanation, let me know if you're interested
So old school and informative, loved it...
Thank you, this is a great explanation and your ms paint skills are amazing
Thanks, if you have any other ideas let me know, thinking of doing something with HTTPS
@@spaghetticode3107 I'm interested to know about VPNs and Proxies, how they work, (and so how they can get around various types of content blocking)
@@spaghetticode3107 Also, do entities like schools/universities/companies often use similar methods to block content, except with a DNS server maintained by some company (which filters out what they want)? Or do they often use some other methods to filter content
Very crisp and Informative...please make more such videos...
Nice explanation, thanks for this
The best explanation ever!
it's sad how an ISP can abuse this. Lately my google search results are very odd and the internet keeps on suggesting gore and horror. I suspect the ISP has some dirty plans. My regular sites keep on going offline, one by one and when I download game mods, the files are corrupted, textures are switched etc. The last time I tried to view games, the genres were very odd, and the content did not match with the genre. I looked for shooters, but the genre stated "action" ... so I guess that is understandable, but then again, it's not a video game term, it's a movie term...
After clicking, the site started suggesting porn games instead. And every other genre did the same. A few years back, I had a massive issue with my internet, where it tried to force me into mommy and toddler content, as rough as possible. I fought back and now it tries to provide murder related content. Should I be scared of my ISP?
the sad thing is most secured sites already block access to direct IP address in the address bar... which is annoying that the address bar must be a string of text now for those specific sites... otherwise i would bypass ISP DNS lookup with just memorizing the IP address itself....
most of the security focused sites have you blocked from accessing their resources if you used direct IP address in the address bar.... its like those django and nginx error pages when you didn't whitelist the IP address or domain name of the server resources to access the web app from the settings files.... so we will need to use a DNS lookup of some sort in the future as more and more site will probably do this to try to obfuscate their server from more people and further increase security for their servers... you could make a dummy app and try it yourself... its the same type of default error page unless they customized it....
Well I'm wondering how is a national block of the web done or upheld and checked…? How much xeeper is it and could you explain it in a simple way like here. Very helpful thank you so far.
It's similar, one way is the government will ask all the ISPs to block a list of websites, which is how EU, I think Australia as well implement blocking. This is very easy to bypass with custom DNS.
A harsher one is through DPI, I have a video on it as well
I want to learn more about vpns proxies dpis and more advanced stuff from where i can learn these? I have basic knowledge about networks.
One of the best ways is to start playing around with Wireshark and get familiar with TCP, the concept of ports, packets etc to understand how connections are made over the internet
Thanks! Great explanation.
My website was not opening only in jio network after some research i found that after deleting ( dnssec ) it will work and it did. but what if i again update it can you help
Not sure what you mean
@@spaghetticode3107 for now webiste does not have a dnssec and it opens everywhere perfectly but when i add dnssec again it will open in limited area on specific network provider. specificly on jio network it wont open. i dont know what is causing this problem
@@video-iiiem wait really? Damn. Can I contact you somewhere directly? Would love to investigate this, but I am not in India currently. I presume Jio DPI is blocking it somehow? Watch my other video on how to unblock with firefox, and try the Cloudflare test in that
I am having the same problem, my website is not working on certain networks. Is there anything i can do to make it work?
But If I try to access a blocked website using its IP address, I shouldn't get blocked by the ISPs right?
They can *also* block the IP address. Also, based on how HTTPS works, sites on, Cloudflare for example, cant be accessed via their IP
@@spaghetticode3107 could you please make a video how using some dns servers let you bypass the ban and connect to the website successfully although it is blocked by ISP?
Thank you so much. great explanation
Today my ISP had blocked Facebook due to some political issues I tried nordVPN to unblock it but unfortunately it didn't succeeded
Did the VPN connection succeed?
@@spaghetticode3107 yes absolutely
get rid of the blue switches it hurts my brain
I love them too much, sorry m9
