Thanks man for your Great Help ,

I want to ask you some questions regarding the Router & IP Addressing .

First, i am still confused for the IP-Addressing, its divided by 3 classes
as the following :-

1. Class A ( start from 1.X.X.X upto 126.X.X.X ).
2. Class B ( Start from 128.X.X.X upto 192.255.255.X)
3. Class C

so if i put any IP-Address in the Class A, Automatically the S/M will be
calss A, and for that the Router will understand that there is a 65365 Host
Per this subnet,

so my question is, if i change the IP-Address to Class c while its already
in class A, is there any Problem will happen to the Router .

For Example, ( 10.1.8.10 ) is class A, is there any Problem if i made it
like 10.1.8.10 / 24 ?

Event worst if tow computers are using the same IP for example, 192.168.1.1. Which one you will access to? 192.168.1.1 in location A or location B? So it is better to use two IP ranges like 192.168.1.x and 192.168.2.x. good luck!
