Thanks - that is what I suspected but I'm not that well versed in
networking issues.

Subject: Re: Network config question
Lionel,
Since you're going to be using point-to-point connections between z/VM and
your Linux/390 guests, the netmask on _those_ connections will (have to)
be
255.255.255.255. The netmask of the connection between z/VM and your WAN
is
a totally separate issue, so if they want you to use 255.255.255.252, then
go ahead. (It's a pretty _small_ subnet, but since you've only got one
system in it (z/VM itself), that should be OK.)

Subject: Network config question
Network guru's I have a question.
My configuration is/will be:
WAN <--> 2216 <--> z/VM <--> lots of Linux guests
I have been given my own subnet for the Linux guests (x.x.x.0) and told I
can use all the addresses from .20 to .254
So I requested dns entries for linux1, linux2, ... with linux 1 being
x.x.x.21 and linux 2 at x.x.x.22 ....
I was told that I should use a netmask of 252 and if I remember from
somewhere that using that netmask will preclude using this scheme.
The question is can I use a netmask of 255.255.255.0 and still use this
addressing scheme ?
thx
