Domain Name Servers
In the previous example, assume each site had a Domain Name Server.
Each DNS contains a listing of other DNS’s in their area.
As your search propagated from one DNS to another, the risk of packet interception
increases.
Imagine the potential for disaster is a DNS were compromised.
Imagine if a host site had multiple servers and one of them was
compromised.
Once compromised, the hacker now has ‘inside’ details on other servers served by
that server.
And the saga continues through other servers, into other servers, etc.
