I'm trying to manually configure the NIC in a normal Plan 9 install on
QEMU. If I run ip/ipconfig (so it gets configured using DHCP) /net/ndb
looks:

ip=3D10.0.2.15 ipmask=3D255.255.255.0 ipgw=3D10.0.2.2
    dns=3D10.0.2.3

and network works fine.

But if I run ip/ipconfig -g 10.0.2.2 ether /net/ether0 10.0.2.15
255.255.255.0 it looks:

ip=3D10.0.2.15 ipmask=3D/120 ipgw=3D10.0.2.2

and I can't use network. Is "ipmask=3D/120" correct?

Is this what makes Plan 9 not boot using network in QEMU?
