No, you are both worng. The answer is simple and practical:
Use a database that has a modern IP adress database type. Like
Postgres. Its IP-adress data types understand and parse both adress
strings and network strings (and, of course -- a network with the proper
netmask set might be interpreted like a host.)
The 32-bit integer trick might, just might make do for IPv4, but a proper
data type is so much simpler to use.
