[one-users] OpenNebula 2.2 not respecting network range?

[Ruben S. Montero]

Hi,

The NETWORK_SIZE is used to compute the network mask for 202 addresses
(including network and broadcast) you need 8 bits so 24 bits for the network
mask. This gives you a network 10.243.19.0/24, so the first IP
is 10.243.19.1and OpenNebula will give you IPs from 10.243.19.1 to
10.243.19.200

Cheers

Ruben
