Random MAC Address Generator. Random Locally Administered Unicast MAC Address: 9e:07:ee:00:74:ec. 9e-07-ee-00-74-ec.
This generator can be used to create IEEE 802 conform local administered MAC addresses. get it. go get github.com/c-seeger/mac-gen-go. Usage. package main. import ( "fmt" "net" gm "github.com/c-seeger/mac-gen-go" ) func main() { // generate a random local administered unicast mac prefix. prefix := gm.GenerateRandomLocalMacPrefix(true)
randmac prints a random MAC address. This utility has been designed to give random MAC addresses to interfaces of virtual machines. OPTIONS-l, --local Generate a local administered MAC. -g, --global Generate a global unique MAC. -u, --unicast Generate a MAC for unicast. -m, --multicast Generate a MAC for multicast.
