Generate random MAC addresses — random

Generates random MAC addresses, e.g. for virtual machines, containers or tests. By default they are locally administered unicast addresses, so they never clash with addresses assigned by the IEEE to manufacturers. Uses R's random number generator, so results can be reproduced with set.seed().

Usage

random_MAC(n = 1, local = TRUE, multicast = FALSE, sep = ":")

Arguments

n: Number of addresses.
local: Logical. Set the locally administered bit (see is_local_MAC())? If FALSE, the bit is cleared.
multicast: Logical. Set the multicast bit (see is_multicast_MAC())?
sep: Separator to use, as in normalize_MAC().

Value

A character vector of n MAC addresses.

Examples

set.seed(1)
random_MAC(3)
#> [1] "FA:80:D6:D1:E0:69" "42:A1:2A:BA:54:B5" "A6:FC:0D:32:14:ED"
random_MAC(1, sep = "-")
#> [1] "4A-06-48-4E-D4-24"
