okay let's meet the cast, one by one 👑

• addr — the IPv4 address itself 📍 fr fr, this is the whole point
• mask — the IPv4 address mask 🎭 she's the filter, the vibe check for the address
• valid — a valid flag ✅ lowkey just says whether this thing is valid or not
• list — the list structure, used internally 🙈 that's right bestie, she's for internal use only, not for you to play with
