How to change LAN address of ADSL router
Change default LAN address of ADSL router is very important. Specially when you work with education institution that has practice class aka lab.
Same IP address will make ‘ip conflict’ and get rid of that information is urgently needed.
Here’s the process, with assumption you allready know how to setup ADSL router :
1. Login to web base configurator

Click LAN button.
2. Change LAN IP address

Enter new IP address in IP address box, for example I enter 192.168.3.1
this address likely rare people use and using that assumption it mean the service won’t get interrupted because of ip conflict.
Subnet mask, I enter 255.255.255.252
Just quick solution for your needs, read this table :
| CIDR Length | Mask | # Networks | # Hosts |
| /1 | 128.0.0.0 | 128 A | 2,147,483,392 |
| /2 | 192.0.0.0 | 64 A | 1,073,741,696 |

| /20 | 255.255.240.0 | 16 C | 4,064 |
| /21 | 255.255.248.0 | 8 C | 2,032 |
| /22 | 255.255.252.0 | 4 C | 1,016 |
| /23 | 255.255.254.0 | 2 C | 508 |
| /24 | 255.255.255.0 | 1 C | 254 |
| /25 | 255.255.255.128 | 2 subnets | 124 |
| /26 | 255.255.255.192 | 4 subnets | 62 |
| /27 | 255.255.255.224 | 8 subnets | 30 |
| /28 | 255.255.255.240 | 16 subnets | 14 |
| /29 | 255.255.255.248 | 32 subnets | 6 |
| /30 | 255.255.255.252 | 64 subnets | 2 |
| /31 | 255.255.255.254 | none | none |
| /32 | 255.255.255.255 | 1/256 C | 1 |
Pay attention to Mask and #Host.
I have this schenario for above configuration :
ISP -> ADSL router -> Proxy Server
Sum of IP ADSL router + Proxy Server = 1 +1 =2 (number of Host)
Thats why I enter 255.255.255.252
Another sample :
Q :If you plan to support 10 host, what is the subnet mask?
A : pick nearest host from that table, as you see its covered by 255.255.255.240 since its support 14 host.
As you see changing IP LAN address isn’t difficult but subnet mask perhaps a problem for some people, using that method I hope you don’t have big difficulty as I did at first effort.
Happy configure router.
