IPV4CALC(1p)

💖 IPV4CALC 💖

okay bestie, gather round, because this little page is ipv4calc from the User Contributed Perl Documentation, section 1p, and she is serving subnet math realness. ✨

---

🌸 SYNOPSIS 🌸

ipv4calc [ --network | --broadcast | --netmask |
           --address | --cidr ] addr

---

🦋 DESCRIPTION 🦋

so like, if you give it an option, ipv4calc does the whole "calculates the requested element from the address" thing and prints that element on stdout. slay. 💅

but here's the tea, and it's a little chaotic: if you give it multiple options, it only prints the first one. that's it. the rest are just standing there, ignored, like 💀

and if you pass no options at all? then it prints the host part of the address, the network, and the broadcast address — all as deduced from the address you handed it. no cap. 🫶

one more thing: if the address doesn't contain a netmask or a mask length, then the default one is assumed. so don't come for her when she guesses, because that's literally the documented behaviour. 😌
