This tutorial will explain to you how it works the SOCKS and Firefox browser.
Open one firefox tab with about:config to see the network.proxy.socks_remote_dns value.
If you want to route your DNS requests through the SOCKS, you’ll need to turn it on.
But because you don’t need to use that then you need to keep to false.
This two result of values will be:
true - have the proxy server perform DNS lookups.
false - perform DNS lookups on the client.
This value controls whether DNS lookups for SOCKS v5 clients happen on the client or on the proxy server.
You can read more about the SOCKS here.
NOTE: Because this use proxy term then you need to know also this about proxy:
– the SOCKS server is a general purpose proxy server that establishes a TCP connection to another server on behalf of a client;
– An HTTP proxy is similar, and may be used for the same purpose when clients are behind a firewall and are prevented from making outgoing TCP connections to servers outside the firewall;
