DNS is used whenever you use the Internet. Every time you send an email or surf the web, you have to rely on DNS. DNS is responsible for mapping between host names and Internet addresses, which is handled by the computer, and latency occurs if the process of connecting to a DNS server is delayed or if the DNS server resolves an address for an excessive length of time. And if you can speed up domain resolution in some way, you can speed up surfing the internet, here is an acceleration method: use
DNS is used whenever you use the Internet. Every time you send an email or surf the internet, you must rely on DNS. DNS is responsible for the ing between host names and interconnected network addresses, which is handled by computers. If the connection to the DNS server is delayed, or if the DNS server resolves an address too long, the access will be delayed. If domain name resolution can be accelerated in some way, the speed of surfing the Internet can be accelerated. The following describes a
Some friends may already know the opendns service, but I did know it through a foreigner's blog today. This website provides free DNS resolution, which is faster, safer, and smarter than the average ISP:

For this reason, it is recommended that anti-virus and anti-spyware be used to protect computers connected to the Internet. In some cases, even using these software cannot completely guarantee your security. It is always a good idea to add another security layer

Dnscrypt is a tool released by OpenDNS that ensures security between the client and the DNS server. Dnscrypt, which runs as a DNS proxy, focuses on communication security between the client and the first-level DNS server, and can cache DNS resolution. In short, the Dnscrypt is able to encrypt the DNS query communication process before the native to the DNS server, thereby preventing DNS hijacking by the network service provider.

(3) Illegal Information in Google Docs must be blocked.
These three reasons have promoted the development of new interception methods. According to speculation, this method is like this: when the client sends an encrypted DNS resolution request, the DNS monitoring end immediately sends a reset signal once it finds that the request is from Google Docs.

Using Firefox and other browsers to surf the internet in Ubuntu is much slower than surfing the Internet in Windows, but careful people will find that the slow time is spent on DNS lookups. Then we can cache DNS in the native computer, that is, a DNS proxy server is set up natively. Commonly used software is bind, Djbdns, DNSMASQ and PDNSD. Let us say, with PDNSD to set up a permanent DNS proxy server, so-called "permanent", that is, after the system restart, the native cache DNS still exist, no
