Hello!
I am doing a small project, where i need to describe the possibilities of locating a logserver on a network.

The question is whether it is possile to imagine this server to have a dynamic IP assigned by a DHCP and how the clients should find the server to send the logmessages.

From what I understand, ordinary DNS requires the IP to be the same, is this true?

The transmissions are to be secure, so an exchange of encryption keys will take place, therefore i cant just send a request package out on the net where the server is!

I have been speculating about dynamicdns services, but it costs money and i guess that is only possible on the internet or if i buy some expensive program to run on a server on the local network :)

Another idea was whether it is possible to assign the server an IP which is always within a certain range. Then letting the clients check which one in this range is the server.

If anyone can point me to reading material on this it would be helpful, or of course if you have some general advice.

Cheers Daniel

btw, is it possible to configure the DHCP server in a way which will give the server the same IP always?
 
The proper method is to use a static IP.

One possibility is to configure DHCP for a very long lease time so that in all liklihood, the server will keep the same IP.

you can also set-up a lease reservation (and enter the IP address you want to use) in DHCP based on the server MAC address. this will ensure that the server always gets the same IP, i have set this up for several machines and it works like a charm. just my two cents.

The proper method is to setup servers with static ip addresses. This is done in dhcp by assinging a client reservation for the servers to use. This allows the servers to always have the same IP address. Go into dhcp, click on the server, scope or superscope, then go to action and select new reservation. Hope this helps.
