This tool was hosted at https://cidr.surge.sh in the past. It is simple tool i modified from Michel MARIANI’s code. The extra functionality allows me to workout the arguments i need for cidrsubnet function while writting terraform. This function will interpolate the calculated ip range you configure at runtime.
CIDR to IP Range
Terrafrom : cidrsubnet(iprange, newbits, netnum)
IP Range to CIDR List
Notes:
- CIDR stands for Classless Inter-Domain Routing.
