-Calculates the network (subnet) address and broadcast address for an IPv4 address with CIDR notation.
-
-**Input format:** `ip_address/prefix` where:
-- `ip_address`: IPv4 address in dotted decimal notation (e.g., `192.168.1.100`)
-- `prefix`: CIDR prefix length (1-30) or subnet mask in dotted notation (e.g., `24` or `255.255.255.0`)
-
-**Output:**
-- `subnet`: Network address in dotted decimal notation
-- `broadcast`: Broadcast address in dotted decimal notation
-
-**Examples:**
-- Input: `192.168.1.100/24` → Subnet: `192.168.1.0`, Broadcast: `192.168.1.255`
