- tl;dr - use a subnet from this range to avoid any weird issues → 192.168.N.0/24 where N is a number from 0 and 255.
RFC1918 within NTNU
NTNU is however using the following subnets within the RFC1918 range, therefore their use should be avoided:
10.0.0.0/8 - Large pieces of this range is already in use; and this block is likely to be used in new subnets within NTNU as well. The general purpose floatin-IP's assigned in openstack is also from this range, and it can thus involve a bit of confusion if both the vm's IP and the floating-ip looks the same. It is thus recommended not to use this block at all.
- 192172.16817.0.0 - The following twelve subnets are partly used in NTNU Ålesund, the rest are free:
