How can I add another mac adress?

[thecumap1]

I happened to find a mac adress in the forum, but I would like to know how to add another mac number and what should I do to be able to read other macs?

This is code

macPath = io.open('/sys/class/net/wlan0/address', 'r')
macRead = macPath:read('*a')
--this is my mac address, just for example
macLists = {'a0%:32%:99%:e8%:e5%:64'}, {'a0%:32%:99%:e8%:e5%:75'}

for _, v in ipairs(macLists) do
macCheck = macRead:match(v)
end

if macCheck then
gg.alert('Your mac address is registered\n'..macRead)
else
local macCopy = gg.alert('Sorry, your mac address is not register','Copy Mac')

if not macCopy then os.exit() end
if macCopy == 1 then
gg.copyText(macRead)
end

end
