Hi,

I'm getting this error during the startup of my tcp/ip.
line 71 is the DEFAULTNET line, as far as i can see 10.0.0.1 is IPv4
address.
I'm using z/VM 5.1
any idea what the error here  ?

0.0.255.0 looks very strange to me. I would expect high-order ones, so
maybe 255.255.255.0


Yeah, but that's because you're used to a SANE way of doing IP
networking, not the VM (copied from z/OS) way.

Assuming that what you mean is that 10.0.0.1 should be the router for
everything from 10.0.0.1 to 10.0.0.254, your netmask there whould be
0.255.255.0.

Why?  Because Net 10 is a class A, so its inherent netmask is
255.0.0.0, and you WANT a final netmask of 255.255.255.0, so the
netmask part YOU have to specify is 0.255.255.0.

Intuitive, eh?

there must be a way to mean
  192.168.0.0 255.255.0.0
mustn't there?
