If I understand you correctly, this is precisely how I'd like to be
able to implement things. Our old subnet would provide for static IP
addresses, either by manual configuration or by DHCP through the use of a
permanent lease; the new subnet will be used strictly for dynamic addresses
from a pool. So my questions are...
Is this possible with the TCP/IP Services DHCP server?
If this isn't possible under TCP/IP Services, what stacks
and/or DHCP servers that run under VMS will support it?
If this is possible under TCP/IP Services, what's the missing
piece that's preventing it from working?
Where is this "DHCP relay" to be found?
FWIW, we only provide service for clients for which we have MAC addresses
registered (registered_clients_only). Host name assignment is via DNS
(assign_name_by_ipaddr).
