Can an Amazon Fire stick connect through a VPN?

[@someone-eb1hq]

what is traffic that goes to isp and website?

[@iMax1975]

After using all the major VPN's I prefer Mulvad. Mulvad is cost effective and does the job.

Where does dns lookup happen? On your computer or from the VPN server? Is a DNS leak when the DNS look up happens from your computer, then the actual connection to the website is through the VPN server? Also do ISPs ever work with private companies like Netflix to block VPN traffic? Cuz I can see the private company being able to peer as deep into the packet as they like, but things like maintaining a list of IP addresses, wouldn’t you need to work with the ISPs for that?

When you use a VPN, all your internet traffic, including DNS queries, should ideally be routed through the VPN server. In this case, your computer sends DNS requests through the encrypted VPN tunnel to the DNS server specified by your VPN provider. A DNS leak occurs when these DNS requests are sent outside the VPN tunnel-directly to your ISP’s DNS server or another DNS server not associated with the VPN. This exposes your browsing activity because, even though the connection to the website is through the VPN, your DNS requests are visible to your ISP or other third parties. DNS leaks can result from incorrect VPN configuration, certain system settings, or flaws in the VPN software. Netflix blocks VPNs primarily by identifying and blacklisting IP addresses associated with VPN services. Detecting these IP addresses is straightforward because a single VPN IP is often used by many users simultaneously. If Netflix detects unusually high traffic from a single IP, it flags the IP as belonging to a VPN provider and blocks access. If Netflix identifies that you are using a VPN, you'll encounter an error code like m7111-1331-5059, which indicates that the platform has detected VPN usage. To bypass this block, switching to a different VPN server may work, especially if the VPN has a large number of servers and IP addresses. In some cases, ISPs might collaborate with private companies to enforce geo-restrictions or block VPN traffic. However, companies usually rely on their own detection methods, such as IP address analysis and DNS setting checks, rather than direct ISP cooperation. While ISPs can still play a role in enforcing these restrictions, such involvement is less common.

@@cybernews makes perfect sense. Thanks 🙏

You can now add Brazil 🇧🇷 to the list of countries under internet censorship

[@arpanmukherjee4625]

In the name of expert level explanation you just gave the most basic things, not really going deep enough to understand under the hood. Its not really telling, how ICMP and IPv4 and IPv6 packets are changed in between. They are rewritten or new packets are generated, that you didn’t show. Is it in the application layer, transport layer or the network layer that these protocols operate? How does it differ from a proxy service? Differences and similarities between VPN servers and routers. When you go this deep then you call expert level. You have just given Noob 1-5 levels.

[@arpanmukherjee4625]

This video is more of an advertisement of VPN services than showing how VPN protocols work. Biggest thing untold is VPN’s main job is NOT security. In a corporate network, VPNs are just used to become part of a private network, and funnily enough your internet traffic from the corporate network is tracked and censored. You just threw around some random generic stuff about encryption, quantum computers and what not instead of getting into the main content. Disappointing.
