Dynamic DNS with static IP configuration

Hi All,
I have a LINUX computer having static IP configuration ( without DHCP). And if this configuration is changed, should this information be updated in the DNS server?

In short, does Dynamic DNS make sense with static IP configuration?

Any comment in this regard is highly appreciated.

Where is the static IP coming from, your router or the ISP?

The static IP is manually configured by the user.

Then it has to be an internal IP, so I assume there is a router involved. I should have been more clear with my question. If you have a server, it can be running DNS. In that case the DNS IP would be static. If you don't have a server then you would be using the DNS from your IP which the router could get dynamically.

Thanks for the reply Don.

I will elaborate on the scenario a bit:
I have proprietory implementation of DHCP client running on a machine .

There is an application which allows user to :
a) enable or disable DHCP
b) if DHCP is disabled, configure LAN interface manually (without using DHCP server )

Case 1:
=======
DHCP is enabled using the above application.
Here when the DHCP client receives the LAN configuration from DHCP server, it sends the dynamic updates to DNS server.

Case 2:
=========
DHCP is disabled and user configures the LAN interface manually. And he could do this often. Now should this information be sent to the DNS server ?

As far as I can tell from what you've said, the DNS stays the same in either case. Usually, users aren't given permission to determine their IP address. There is really no reason for that. As long as they have access, that's all they need.

Thanks for the reply Don.
You are right..IP address may not be required by users to know as far as we have DNS. But IP address or host name could be changed by user.

So i was not sure whether we should be updating the DNS server database using dynamic DNS in case of such static configuration changes.
