 Why should you try custom DNS ?

Speed up your browsing experience.
As web pages become more complex, referencing resources from numerous domains, DNS lookups can become a significant bottleneck in the browsing experience. Whenever a client needs to query a DNS resolver over the network, the latency introduced can be significant, depending on the proximity and number of nameservers the resolver has to query.

Improve your security.
Because of the open, distributed design of the Domain Name System, and its use of the User Datagram Protocol (UDP), DNS is vulnerable to various forms of attack. Public or “open” recursive DNS resolvers are especially at risk, since they do not restrict incoming packets to a set of allowable source IP addresses.
