Beside the IP address; Another piece of info you need is the subnet mask.
Together, they determine the subnet group.
So depending on the subnet mask to be used; 130.5.1.0 and 130.5.2.0 might or
might not be in the same group.

Subject: subnetting and tcp/ip
Am studying tcp/ip now, and have a couple of questions (believe me, this is
the basics for you guys!) Im reading a tutorial on the web, and still am a
little confused. I need someone to go line by line with me, please! In
return, Ill give you a cookie :> Take the following:
1. I have a network, ip address 130.5.0.0 (why is it 0.0)? Do all network
#s end in 0? And for Class B to have the network address, must it be
x.x.0.0? Cant I have something like 172.5.5.0? I understand 130, for class
b, but where did they get 5 from?
2. Next I have the list of ips on my network, per pc (or device). Such as
:
130.5.32.0
130.5.64.0
130.5.160.0
130.5.224.0
So, are they on the same network or not? I know that each pc must have its
unique host--I dont want you guys to think Im that basic with this; yes Im
weak, but I do know that with class b its network.network.host.host--> So,
the host id seems to be on the same network while the host is having a
dfferent id. I just get confused when I read a class B and think, which
parameter has to be changed? The 3rd octect ONLY or the 4th as well.
