allow only 2 ip's to view graphing tool

Hi i have setup graphing tool on my mikrotiks but want to now if it is possible to allow more than one ip address? I have set only to allow 192.168.0.17 but also need to add 192.168.0.16. I dont want to allow 192.168.0.0./24 becos then everyone can see the info.

The bottom is what im talking about. will it work?

[admin@MikroTik] tool graphing interface> add interface=ether1
... allow-address=192.168.0.016 allow-address=192.168.0.17 store-on-disk=yes
[admin@MikroTik] tool graphing interface> print
Flags: X - disabled

INTERFACE ALLOW-ADDRESS STORE-ON-DISK

0 ether1 192.168.0.0/24 yes
[admin@MikroTik] tool graphing interface>

use 192.168.0.16/31

sorry for asking but what will 192.168.0.16/31 do?

Allow 192.168.0.16 + 192.168.0.17

And /30 will allow 192.168.0.16 + 192.168.0.17 + 192.168.0.18 + 192.168.0.19
/32 will just allow 192.168.0.16

thanx i will add that now
