Beginner question on DNS ?

[Guest]

Dear all

I have a begiiner question on DNS
I order to configure coreccly a DNS server, does all client station has to be recorded manually inside DNS server database or is it the clinet which is identifying it self to the DNS server when a local netowrk connection is configured.

What I try to understand is that if all my client are using DHCP, when the configuration of TCP/IP parameter get apply does all client send a notification to the DNS server to add it to its database

Now imagine that I made a mistake and I rename the name of on client, how the DNS databse will be updated

How does it all work

Traditionally, DNS servers had to be maintained by hand.
An administrator would add A and PTR records in the Zone Files.

This is hopeless if the machines have dynamic IP addresses.
So modern DNS servers support Dynamic Update.

Also, the client should support DDNS registration.
( In 2000/XP: Register this connection in DNS check box. )

The DHCP server can also help out by doing DDNS registration
on behalf of old clients which don't do DDNS registration.

If you re-name a client, or it gets a new IP address, it will
register its new name and IP address in DNS.
