IP Networking

My work has a Unix based system that currently has the IP address 192.9.2.25
We recently changed internet providers from DSL to Cable. By doing so, we had to get a new router (Belkin) since the DSL provider had a wireless router/modem in one. With the DSL setup, I was able to change the router's IP address to 192.9.2.1 and everything worked great when logging into the system from another computer.
The problem I'm having now is that the Belkin router won't let me change it's IP address to 192.9.2.1. I called Belkin and they said the first two numbers must be 192.168 and that there's no way to change that. I wish I knew that before I bought it. I spoke with the company who's software we use on the Unix machine - which is the only thing on the server - and they said I'd have to change the IP address of the server and all the printers. They want to charge me for hardware support. I don't see it taking an eternity to do - I just want to do it right.
That being said - how do I change the IP address on the Unix server? I did a search on this forum and found this -
(copy and paste - I can't post URL's yet.) unix.com/ip-networking/6954-how-reconfig-ip-address-solaris-unix-system.html

My info is as follows on the server when I went to ifconfig -a:
net0: flags=4043<UP,BROADCAST,RUNNING,MULTICAST> MTU 1500
inet 192.9.2.25 netmask ffffff00 broadcast 192.9.2.255
perf. params: recv size: 32768; send size: 32768; full-size frames: 1
ether 00:04:75:ea:81:fd
lo0: flags=4049<UP,LOOPBACK,RUNNING,MULTICAST> MTU 8232
inet 127.0.0.1 netmask ff000000
perf. params: recv size: 57344; send size: 57344; full-size frames: 1

So...how do I permanently change the IP address and what commands do I use to get into it? What should I make the IP address? 192.168.2.25?

My internet info is as follows:
Cable Modem WAN 10.1.10.11
Belkin Router LAN 192.168.2.1
Submet Mask 255.255.255.0

If possible, can you please explain it like I'm 5 years old and never used Unix before? - because I know nothing about UNIX. It took me a little just to figure out how to get that above info to show on the screen. I do have access to ROOT if that helps. All I know is how to get to the # symbol and type ifconfig -a so far and it is Sun Solaris.

Thanks!

Which Solaris, Open, X86 or SPARC? Try "uname -a". Solaris forum might be better. This looks good, googled up as 'oracle sun slaris change ip address': http://forums.oracle.com/forums/thre...54286&tstart=0

I suppose you could leave the subnet alone. You can trick the packets into flowing with second IP addresses on pseudo devices, manual routes and an ARP server forcing packets to route through that IP/MAC.

Hi Len351
Can send us the result of:
# uname -a (to know what OS do you have)

#netstat -rn (what Gateway do you have)

This server access to Internet, if the answer is correct, please send me, the following:
#cat /etc/resolv.conf
or
#cat /etc/inet/hosts
