How to find IP belongs to which network?

[jaigs_27]

I have a file in which I have stored all the network e.g.

10.53.50.0/23
10.53.54.0/23
10.160.92.0/24
10.160.250.0/24
10.151.88.0/23
10.156.54.0/25
10.51.144.0/22
10.51.50.0/23
10.62.8.0/21
10.53.26.128/25
10.53.27.128/25
10.200.10.0/21

Now I want to find IP belongs to which network from abobe file and if more than one ips belongs to the same network than I want to know that those IPs.

Is there any way to do?

Every one of those subnets is RFC 1918 private IP space.

I did not get you.

My question is "I want to know the network of that IP from above mentioned list"

Sure - you need to understand what part of the IP is the "network address" and which part is the "node address." You have each network already listed - expand each one out and you'll see if any overlap.

10.53.50.0/23 => Network address that includes all nodes from 10.53.50.0 > 10.53.51.255
10.53.54.0/23 => Includes all nodes from 10.53.54.0 > 10.53.55.255

And keep going...just glancing over the list, it doesn't appear any overlap.

Could you please explain more about this "it doesn't appear any overlap"

and above list is just an example I have bigger list.

I don't know how do this.
But I know the DNS server --bind 9 have the capabiltiy you mentioned above.
Perhaps you can get some tips form soruce code of bind 9 (The "view" function).
