We are using class-C IP addresses in our network setup.
The first scope of IP addresses are in 192.168.0.xxx. Since all the IPs are exhausted in this scope we created another scope of Class-C IP in the same Domain Controller. This scope has IP addresses in 192.168.3.xxx.
The issue we are facing is, whenever a client with IP address in the 192.168.0.xxx scope, tries to copy a file to a client with IP address in scope 192.168.3.xxx the copy is dead slow.
For e.g., transfer rate of a 1 GB file between clients in same IP scope will be around 35 MBPS or more whereas copy of the same file between clients in different IP scope will be around 5 MBPS or sometimes even lesser (sometimes drops to 0).
What is happening here? Is there a solution to make copy faster. The type of work we do requires huge data transfer between clients and changing the IP scope to a class A scope may be a out of question since we are a little short on resources to do the transition.
Am I missing some setting or something on the Domain controller or the router which is causing the copy to go so slow.
This issue is not fixed to any specific kind of OS, it happens across all types of OS we have - Windows or Mac.
Switch to a class A network so everyone knows how to find everyone else. 10.x.x.x. – bmargulies – 2012-07-03T12:26:04.920
Classful networking has been replaced by CIRD since 1993. This means no more 'Class A' etc etc, but /X. E.g. /8 for old class A networks. This also allows you to create a /23 with up to 512 IPs in a network rather then tie two /24 ('c')'s together.
