Hi,
I'm looking for any tool or a way I could specify a CIDR and the prefixes
that are being used within this CIDR and the tool show me all free
supernets.
Example:
192.168.0.0/24 - CIDR
Used subnet's:
192.168.0.1/32
192.168.0.8/27
192.168.0.64/26
192.168.0.68/32
192.168.0.96/29
Tool Result => Free Subnet's:
192.168.0.2/31
192.168.0.4/30
192.168.0.32/27
192.168.0.128/25
Regards,
John
