go-ipprotocols is a Go library that provides a mapping of IP protocol numbers to names and vice versa. It uses a static mapping based on IANA's protocol numbers, allowing developers to easily retrieve protocol names from numbers and numbers from protocol names.
- Get protocol name by number: Quickly look up the name of an IP protocol using its number.
- Get protocol number by name: Find the number associated with a given IP protocol name.
You can install this package by using go get:
go get github.com/tomvil/go-ipprotocols
After installation, you can import the library into your Go project and use the functions GetProtocolName and GetProtocolNumber to perform protocol lookups.
package main
import (
"fmt"
"log"
"github.com/tomvil/go-ipprotocols"
)
func main() {
// Get protocol name by number
name, err := ipprotocols.GetProtocolName(6)
if err != nil {
log.Fatal(err)
}
fmt.Println("Protocol number 6 is:", name) // Output: Protocol number 6 is: TCP
// Get protocol number by name
number, err := ipprotocols.GetProtocolNumber("TCP")
if err != nil {
log.Fatal(err)
}
fmt.Println("Protocol TCP has number:", number) // Output: Protocol TCP has number: 6
}
