Surf the Internet Faster with
OpenDNS!by Rich Pryor
One Simple Tweak Can Speed Up Your
Internet Experience, Filter Porn and Offensive Sites, AND
protect you from the Conficker Worm!
If there is one thing I love, it is something awesome and free
that speeds up my computer or makes me more productive. If I
also get some cool, free features thrown in, well that makes it
even better! That pretty much describes OpenDNS, which is why I
use it exclusively as my DNS resolver.
"But Rich, what the heck is a DNS
Resolver?" If you already know, skip a paragraph, but for those
who don't...DNS is short for Domain Name Service. Briefly,
computers speak in numbers, not in words or letters. When you
type "www.gmail.com" into the address bar of your browser, your
computer contacts a DNS Resolver, which returns the actual IP
address of the computer that Gmail wants you to contact to
login. The details of how that happens can get complicated, but
what you need to know is, the faster your DNS Resolver returns
that IP address, the sooner you are logging into Gmail, or
whatever other site you are trying to get to.
Most of the time, you are using
DNS servers that are run and managed by your Internet Service
Provider (ISP). (If you are a home user on DHCP, they are
assigned to you automatically when your computer or router
requests an IP address. If you have a static IP, they will have
given you the DNS servers to configure your router with at the
same time you configured your IP address, subnet, and gateway
information.) Often these servers are overloaded, resulting in
less-than-stellar performance. OpenDNS, on the other hand, has
numerous super-fast DNS servers located in data centers around
the world. Your request is automatically handled by the one
closest to you. OpenDNS answers billions (with a "b") of
requests a day and their servers have a huge, huge cache.
Therefore, OpenDNS servers can service your DNS request faster,
and your web surfing will be faster as a result. Sweet!
But OpenDNS doesn't stop there.
They also provide free content filtering! Are you a home user
that wants to keep your teen-ager off the adult sites, or a
business owner wanting to keep your employees focused on
work-related sites? No problem. Once you sign up for a free
account with OpenDNS, you can log in and configure what sites
you want to allow and restrict from a list of 50 categories.
OpenDNS Web content filtering uses the iGuard database from St.
Bernard Software, one of the most trusted names in the
industry, to power all categories relating to "Adult" content.
And hand-in-hand with content filtering is automatic phishing
protection. OpenDNS servers maintain a huge list of sites that
suspected of phishing - that is trying to trick you out of your
credit card numbers or other sensitive financial
information.
To top it all off, using OpenDNS
as your DNS resolver will protect you from the Conficker worm. Even if you have
been infected with it, by using OpenDNS, the worm will be
blocked from "phoning home" and thereby being activated to
wreak havoc on your machine! If you are at all nervous
about Conficker, you should switch to OpenDNS.
What's the catch? Naturally they
can't offer such an awesome service with no catch whatsoever,
but this one is easy to swallow. To quote the OpenDNS site:
People frequently ask us how
we can offer such a fantastic service without charging a dime.
OpenDNS makes money the same way Google and Yahoo do — by
showing relevant ads when we show you search results. Our
number one priority is to deliver the best possible user
experience, which means you won't find any pop-ups, pop-unders,
or anything like that around here.
