Contact various Internet access providers directly, and determine what
protocols and datalinks are necessary for the particular provider.
You do not need to be running a WWW server on the local systems,
though you may/will need to obtain and install an IP package such
as DEC TCP/IP Services for OpenVMS (UCX) -- you will need to work
with the provider to determine an appropriate (cost/speed) datalink,
and to determine what protocols are supported by the provider.
Once the general datalink options and requirements are determined,
the necessary local hardware and software can be determined.
