I do have basic understanding of IP Address which is unique address for each System either in an organization or over the internet. But i want to understand what is IP address range
Lets Say we have below IP'S in my company
- 10.110.80.9
- 10.145.60.4
- 10.450.90.10
Will 10.0.0.0 represent IP range of my organization or it should be something like 10.0.0.0/16
I have few questions or clarification
I am not aware of significance of value after / , i have seen IP address range like 10.230.8.6/22 what does /16 or /22 represent
If i set firewall rule to allow communication for all IPs of my compnay will below IP address range take care of it
10.0.0.0/16 . should i assume that any IP address that start with 10. will be part of this address range ?
