# Go-CIDR

---
## Description
The purpose of that library is checked an IP inside from a CIDR.
---
## Project structure
The project structure explained what contains what.
```shell
├── cmd
│ ├── bootstrap
│ │ └── bootstrap.go // point where init the service
│ └── main.go // entrypoint of the service
├── pkg
│ ├── config
│ │ └── config.go // config structs, methods and functions
│ ├── ip
│ │ ├── ip.go // logic to create the hosts from cirds
│ │ └── ip_test.go // test file for ip pkg
│ └── store
│ └── memory
│ └── memory.go // storage in memory
└── README.md // Readme
```
----
## Example
Using storage in memory:
```go
package main
import (
"time"
"log"
b "github.com/jrmanes/go-cidr/cmd/bootstrap"
m "github.com/jrmanes/go-cidr/pkg/store/memory"
)
func main() {
// load configuration
cidr := []string{"10.251.0.0/16", "172.18.0.0/16", "192.168.0.0/16"}
// Run the process in order to load the hosts inside the cidr
b.Run(cidr)
now := time.Now()
log.Println("---------FROM MEMORY------------")
ip2CheckInMemory := "12.251.0.162"
existsInMemory := m.CheckIfIpExistsInMemory(ip2CheckInMemory)
if existsInMemory {
log.Println("IP found ip2CheckInMemory (", ip2CheckInMemory, ")", existsInMemory)
} else {
log.Println("IP NOT found ip2CheckInMemory (", ip2CheckInMemory, ")", existsInMemory)
}
log.Println("elapse using storage memory:", time.Since(now))
log.Println("-----------------------------")
}
```
