Hi<br />
I wanted to get some help on understanding a little more about IP addressing, specifically I want to know what this means:<br />
<br />
10.210.230.0 / 23<br />
<br />
Has this got something to do with subnetting?

IP addressing help

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
