Static name but DHCPServer

mahoney · 09-01-2005, 06:41 PM

Hello,
I have been recently tasked to figure out a way to have a DHCP server where the IP address is changing but the name of the Hosts is not.
These computer (s) are going on and off line frequently.

So I will also need to be able to see when a particular PC is on or off line.

I am not certain what the best way of doing this is.
My networking skills are limited and I have had deal with it much lately so my volatile memory has failed me.

Any information would be helpful,

Thanks,

Dynamic DNS, there are tons of places who offer this service for free.

Thanks,

I guess my question would be how do they ISP do this ?

I am not certain how to approach this idea/ concept and not sure were to go to find more information and what to look for when searching.

You have to install a small soft on your box which will send your new ip to their dns servers each time it changes (or update it on a regular basis).

You can find such services for free on the web, the best known is surely dyndns (www.dyndns.org), but there are a lot others which do exactly the same (www.noip.org ..)

You can find a list here : http://www.technopagan.org/dynamic/#TheList or try to google for "dynamic dns"

Thanks,

I guess I failed to mention that this would be running behind the fire wall and would not be exposed to the outside world.

Hi,

You can maybe take a look at www.prout.be and see if their "ProutDNS" soft corresponds to what you want to do ...

Summary:
ProutDNS allows you to provide your own system of dynamic dns with your domains
Currently it can:

- register new users
- register A, MX, NS and URL redirections in multiple domains
- register a predefined maximum number of hostnames/user
- update the ip address of existing users for an hostname or all in one query using
a simple commandline browser like lynx
- allows users to modify properties of their dynamic redirection like MX, NS and Wildcard
- allows users to modify their infos
- allows users to delete their hostnames/accounts if they don't need it anymore
