hey guys, so i'd like to make a small program to assign ips if we need to for lan parties. I got a C compiler called "open watcom" but cant figure it out. whats a good complier for C that runs on windows? whats a good source for C commands? and last is there a way to get the list of variables used for windows? (the variable name assigned to hold the computers IP's)

i agree Kcircyrd but i had an account here so i posted here, i really have no experience. the most i have done was make simple programs in java with eclipse and i only executed in the complier. never could figure out how to make it a jar file really. i am taking a C class this seme so i can wait for that to start up.
thanks anyways.

Don't know about "LAN parties" other then what i just googled online: you're having a bunch of people over with their own computer so you can share share the LAN and game?
In which case, i think might be much simpler to configure your router to assign a specific ip for a specific computer (it differentiates and uniquely identifies them using each computer's hardware MAC address which is unique per computer). Router need be updated only one time when a new computer arrives. Would that approach meet your needs?

use DHCP for all players and you then need only one static IP for the game server.
back on the topic:
Multiple issues confront you on this question.
In a domain controlled environment (ie commercial companies) the DNS+DHCP servers
are configured by the admin according to the company policies.
For home users (ie workgroups), we have the simple technique show at the top or
the brute force approach of assigning static ip address on every machine.

Ummm.. Maybe it wasn't clear from the post, but the "paradigm" is quite simple and quite common for home routers.use DHCP for all players and you then need only one static IP for the game server.

(3) is not the paradigm for controlling addresses on a network;

It's called DHCP Address Reservation (i.e. Reserving IP addresses based on the requesting computer's MAC address).
The function is found in all the Netgears i've used (and other vendor routers too tho i can't recall specific makes/models.. you can go look it up for your own)
I can one-time setup/"reserve" a constant, pre-defined IP address for a computer with just a few mouse clicks. (And IMHO, i find Address Reservation even simpler since i can do it all from my router).. And btw if advising someone set a static IP on a computer i'd advise they STILL need the extra steps to configure their router to remove the static IPs from the DHCP assignment range
/* edit* / as that is, otherwise, a common reason for IP address conflict error messages people reportOn a netgear router:
1. Click LAN Setup then click Add Address Reservation (see images)
2. Simply select the computer you want to reserve. (Use the default IP adress settings shown or you can change it if you like)
3. Then click to Add and Apply your settings
Seems pretty simple router setup, not brutal, to me
well..... thanks for helping me with this but i just wanted to make this to help me understand C before my class begins. More like a project than a problem i have. we have set static ip's but i just wanted to make a simple program to you could run to set a different IP/Subnet to each machine.

That is a make-work, non-productive approach.
Forget 'C' programming as a solution and drop all static IP addresses --
just use DHCP and everything will sort itself out. For the game server system, set those as
static at the high end of the subnet, eg x.x.x.253

if you're reporting the true name of the device (ie switch) then there's nothing to figure out,
a switch has no configuration whatsoever (nor does a hub).
A switch *must* be connected to a router and that's where the subnet is controlled.
For all your players, have them set the TCP properties for IP and DNS to AUTOMATIC
and delete all static information that may already exist.
