CIDR headroom

Free space of each VPC CIDR (every subnet counts). Less than {{ low_pct | int }}% free is flagged. The recommendation is the first /{{ r.secondary_prefix }} secondary CIDR that passes the AWS association restrictions and does not overlap any network IPLens knows (all accounts' VPCs, Transit Gateway and peering routes). Read-only: nothing is created in AWS.
