DNS and DHCP in the same time and in the same LAN

[Dan Jennings]

The concept goes like this:  If you are really interested in
contacting a system that is assigned an IP address by a DHCP
server by it's hostname, the DHCP server must update the DNS
server dynamically when it serves out an IP address to clients
and when it expires the leases later on to remove the DNS
entries for client's hostnames and addresses.

The dynamic update of the DNS server by the DHCP server is
typically implemented as a call to a script, including the
DNS-specific info as arguments, that contains the nsupdate
command.  The nsupdate command is the executable used to
apply DNS resource record updates to a running DNS server.

In this way, the DNS server will always contain accurate 
hostname to IP address mapping, whether a system has a 
statically or dynamically assigned address.


  Hope this helps,

  Dan
