RE: Print Distribution and IP connected Devices

Just clarifying what may be some missed points:

DHCP can be configured with RESERVATIONS to consistently assign the same
IP address to a particular device. That is a compromise in the effort
involved, you still don't have to configure each local device, it's just
an entry in the DHCP server. In a content filtering environment, I
allow devices to get a dynamic address, but that pool is the most
restricted. Then I create a reservation into an appropriate pool to
give the device the desired level of filtering rules.

If you application can't resolve DNS by name, yes, it's broken as
designed.

Conceptually, even if dynamic DHCP assigned addresses and updated the
DNS server, print by name should work. However, DNS servers use a "time
to live", they don't validate the address until that time expires.

MVS doesn't need a DNS "server" to be able to resolve names; it just
needs a list of servers to access for that service. I don't know if MVS
DNS client "caches" addresses or not or if it honors the TTL for those
entries.

I support several hundred printers across the state. What the
networking people are planning probably won't work with what has been
said about CA Spool needing IP addresses. You require static IP
addresses for each printer; how they do it is the net admins problem.
Make sure your users know whose problem it is as well.
