how define network with mask 8 for dhcp server?

Sam,

Unless it is on paper, do not even try to offer a /8 network, makes
subnets out of it and have as many DHCP servers as you need.

It is simply impossible to run a /8 network, so it make no sense
offering such a thing. Limit your scripts to what makes sense.

Best regards,

Olivier
