Why use DNS ? Anonymous proxies

[lvu52]

I have tried using Google DNS to access websites that are filtered likely by my government. I think it used to work fine with Facebook but now it didn't. Why could I pass the filter with just a minor change of DNS ? Except Google, are there still other DNS's that are free for me to use ?

Also, I used to use proxies from this site http://www.proxy4free.com to access different websites but now they don't provide the ports anymore for me to insert into port area in my browser. How can I check which port a particular free proxy is used so I can get it done with my browser ? Thanks.

I guess one way to nobble the net is to prevent successful DNS lookups by excluding from the lookup table IPs for those domain names. Most users would not know of other DNS servers that could be used. Yes, there are some other free ones. I recently noted these as open DNS servers: 208.67.222.222 and 208.67.222.200 but of course maybe they, too, have been blocked.

Besides blocking DNS lookups, your govt probably also totally blocks certain sites by a separate technique that can't be so easily evaded. Are you saying you now can't get to facebook?

Also, I used to use proxies from this site http://www.proxy4free.com to access different websites but now they don't provide the ports anymore for me to insert into port area in my browser. How can I check which port a particular free proxy is used so I can get it done with my browser ? Thanks.

It would seem pointless for proxy4free to provide an address without a port. Maybe try some other list of free proxys?

Most of those sites are ones that you surf to, and then on their home page in a box there type in the web address of the banned site you want to read. So it looks like it defaults to port 80. At proxy4free there are lists of other sites where you can obtain more proxies, e.g., http://www.centurian.org/

Just tried a google search on "free dns server" and this site came up, though I don't know how current the information is. http://theos.in/windows-xp/free-fast-public-dns-server-list/

DNS, or Domain Name System, is a crucial component of the internet that translates domain names (such as www.google.com) into IP addresses that computers can understand. This allows us to access websites and other online resources easily without having to remember a series of numbers.

Using DNS is important for several reasons. Firstly, it helps to improve internet speed and efficiency by reducing the amount of time it takes for a website to load. Without DNS, we would have to manually enter the IP address of a website each time we wanted to access it, which would be time-consuming and prone to errors.

In the context of accessing filtered websites, using DNS can help bypass censorship or restrictions imposed by governments or other entities. By changing your DNS to a different provider, you may be able to access websites that were previously blocked. This is because different DNS providers may have different IP addresses for the same website, which can sometimes allow you to bypass filters.

In regards to your question about using anonymous proxies, these can also be helpful in bypassing filters and accessing blocked websites. However, they can also pose security risks as they act as intermediaries between your computer and the website, potentially exposing sensitive information. It is important to use reputable and secure proxies if you choose to use them.

In terms of finding free DNS providers and checking which ports a particular proxy uses, there are many resources available online. However, it is important to use caution and research the credibility and security of these sources before using them. It may also be helpful to consult with a trusted IT professional for guidance and assistance.
