[Info-vax] What is definition of a network for TCPIP SET /ACCEPT=NETWORK?

[Dymaxion Development]

I am getting the following error for (note the a and b are placeholders for actual numbers):

$TCPIP SET SERVICE SSH /ACCEPT=NETWORK=(a.b.241.0:255.255.255.0,a.b.242.0:255.255.255.0,a.b.243.0:255.255.255.0)
%TCPIP-E-SERVERROR, cannot process service request
-TCPIP-E-INVQUAL, invalid qualifier value for /ACCEPT.NETWORKS
-SYSTEM-F-TOOMUCHDATA, too much optional or interrupt data specified

The site has 7 full IP ranges to allow (this is just 3). How would you enter them?

The limit is 16 which I took to mean 16 network specifications not 16 IPs?

Any help would be appreciated.

TIA,

John Tran
