Hi all, I’ve created a subnet calculator for both IPv4 and IPv6 written in C.
As well as using it to find a network for a given IPv4 CIDR range, you can request multiple subnets with the -s option: ./netcalc 10.20.30.40/24 -s4 Or use the -6 switch for IPv6 addresses: ./netcalc -6 8c6b:dbfb:5c73:8f14:f815:a4a2:5dab:38b0/110 You’ll need to compile it with the math library linked: cc -Werror -Wall -o netcalc netcalc.c -lm Only tested on OpenBSD 6.5 and macOS Mojave 10.14 but it's probably compatible elsewhere too. https://jamsek.dev/resources/pub/netcalc There's also a man page.
