# How can change horizon to show mac-address in instances table

Hi All

today the horizon gives list of networks and IP-address associated to instance in the instances table view

in the IP-Address column we have :

Net1
90.90.90.1
Net2
70.70.70.2


so in order to check mac-addresses corresponding to each of instance network ports , i need to check the network section

i would like to give also mac-address to this table like this :

Net1
90.90.90.1/fa:16:3e:36:51:1f
Net2
70.70.70.2/fa:16:3e:36:b2:d3


how can i do such ? where should i look for first ?

thanks
