If you have known me for long you will know how much I tout performance and safety on your PC, MAC (OSX) (cause Apple products are the easiest hacked computers), or Favorite Linux Distribution (Fedora Core, Ubuntu, Suse , etc…).

The best way to keep your internet surfing clean fun and fast not to mention safer. Using a controlled or 3rd party DNS provider.

First we should explain what a DNS is….

From Wikipedia:

“The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participants. Most importantly, it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. An often-used analogy to explain the Domain Name System is that it serves as the "phone book" for the Internet by translating human-friendly computer hostnames into IP addresses. For example,www.example.com translates to 192.0.32.10.”

"…The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain. Authoritative name servers are assigned to be responsible for their particular domains, and in turn can assign other authoritative name servers for their sub-domains. This mechanism has made the DNS distributed and fault tolerant and has helped avoid the need for a single central register to be continually consulted and updated.”

What does this mean?

Its how you use English names and translate them into a Physical Address or IP address.

Every day your router goes out and gets the latest dictionary of DNS addresses that you request via multiple DNS servers.

So how does this help me with anti-malware and site blocking? Well there are companies and services that will take over or become a man in the middle to filter you requests and block known DNS names that harbor unsafe, disgusting or unwanted web content. The greatest part of this filtering is you do not have to install software to get this protection and monitoring like many web filters do (Net Nanny and Such.).

Today I am going to focus on 3 services (DNS):

 

OPENDNS: My favorite by far. Create an account and setup your filtering preferences. Take the DNS IP address’s and magically it all works. DNS address: 208.67.222.222 and 208.67.220.220

GoogleDNS: I like the speed however not sure exactly what “other” things google is tracking. DNS address: 8.8.8.8 and 8.8.4.4

NortonDNS: This is a beta program but promises to do as well as its software suite with this extra bit of protection. DNS Address: 198.153.192.1 and 198.153.194.1

 

With all three of these services you will see significant speed increase accessing your favorite sites. You will also see better protection with “accidental” clicking on bad links.

Be safe and if you have any questions please feel free to call us (801)682-3064 for assistance.
