An overlapping subnet can sit quietly for years - until two networks need to connect. A duplicate CIDR (Classless Inter-Domain Routing), an IP address range such as 10.0.0.0/24, may cause you no immediate trouble while networks remain isolated. During an expansion, acquisition, or cloud migration, however, that same overlap can become a connectivity blocker. Cloud peering is one place where the issue becomes unavoidable.
