Setup our OWN DNS Server

[Daniel Ryslink]

Hello,

First, you have to tell us if you wish to run and maintain an 
authoritative DNS server (meaning a server propagating authoritative 
information about your domain names), or a recursive caching nameserver 
(a DNS server performing recursive queries on behalf of other client 
devices [phones, laptops, web servers, mail servers, workstations]) that 
cannot or should not resolve these queries by themselves.

These two functions are radically different, have different requirements 
on hardware and bandwidth, and are really best kept separate because 
mixing them up causes all kinds of problems. If you want do do both, you 
should dedicate separate machines for the purpose.

Please also note that if you want to run authoritative DNS servers, you 
need at least two, preferably in geografically diverse locations and 
different ip ranges (so that one disaster does not wipe your domain 
names out of existence). Some ISPs or hosting companies provide a 
service called "slave DNS", though, allowing you to run a primary 
authoritative server (master), and use their server as a secondary 
authoritative server (slave).
