it is long time and i think that CIDR is just a routing method that allows routers reduce routing table size.
tonight, i was reading a book mentioning that CIDR saves address space.
This makes sense of what follows:
- assume your organization has been assigned two class C ranges 18.104.22.168 and 22.214.171.124
- CIDR may help reducing tables by advertising both as 126.96.36.199 /23 [255.255.254.0]
my two questions are:
- Is 188.8.131.52 a broadcast address?
- Is 184.108.40.206 a network address?
if so, then we have not saved address space.
Actually, i have found many misundestandings regarding network concepts in this book and other books of the same publisher, but i still need to understand this in depth.
BTW, this is not a cisco press book
thank you in advance
