Debating between using an in-house or outsourced DNS provider? Learn the benefits and downfalls of both, and decide for yourself.

1. WHAT'S THE
DIFFERENCE
IN-
HOUSEDNS
OUTSOURCEDDNS
An in-house
server or rack
that hosts an
organization's
query traffic
A third-party
provider that
routes traffic on
a global
network
WHICH IS THE ONE FOR YOU?
In-house
systems are
costly to set-up,
and there are
dozens of other
costs to keep
users online:
DNS
providers
don't charge
set-up fees,
and you don't
have to spend
more for
greater infra-
structure. Just
one low
monthly fee
Software
Bandwidth
IT staff
Maintenance
And
then
there are
security costs
like firewalls &
individual
server conf-
igurations
BUT THIS STUFF
DOESN'T EVEN
MATTER!
If the in-
house system
gets flooded by
an attack or too
many visitors, it
will be knocked
offline before
the traffic even
reaches the
firewalls
In-house
systems
use Unicast
networks
That means they
operate out of
one location
It also means
there's a single
point of failure
DNS providers use
IP Anycast networks which
contain many geographically
unique Points of Presence (PoP)
Each PoP has dozens of name
servers, each exponentially
increases layers of redundancy

Resolution times
are faster because
the name servers
are closer to the
querying clients
