"""Generate an IPAddress with compile-time initialization instead of runtime parsing.
This function parses the IP address in Python during code generation and generates
a call to the 4-octet constructor (IPAddress(192, 168, 1, 1)) instead of the
string constructor (IPAddress("192.168.1.1")). This eliminates runtime string
parsing overhead and reduces flash usage on embedded systems.
Args:
ip: IP address as string (e.g., "192.168.1.1"), ipaddress.IPv4Address, or None
Returns:
IPAddress expression that uses 4-octet constructor for efficiency
