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.)

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 -------------------------------------------------------------------- Lionel B.
