iprange

iprange is a library you can use to parse IPv4 addresses from a string in the nmap format.

It takes a string, and returns a list of Min-Max pairs, which can then be expanded and normalized automatically by the package.

Supported Formats

iprange supports the following formats:

• 10.0.0.1
• 10.0.0.0/24
• 10.0.0.*
• 10.0.0.1-10
• 10.0.0.1, 10.0.0.5-10, 192.168.1.*, 192.168.10.0/24

Usage

package main
import (
"log""github.com/malfunkt/iprange"
)
funcmain() {
list, err:=iprange.ParseList("10.0.0.1, 10.0.0.5-10, 192.168.1.*, 192.168.10.0/24")
iferr!=nil {
log.Printf("error: %s", err)
}
log.Printf("%+v", list)
rng:=list.Expand()
log.Printf("%s", rng)
}
