Just a quick question for you networking wizards out there:

I am trying to configure a TCP/IP-based network printer. This printer
will reside on an isolated network so a default gateway is not
needed. The network configuration of this printer is accomplished via
HTTP through a standard web interface. Although I do not want to
specify a default gateway, the printer's configuration does not allow
me to leave the "default gateway:" field blank. Is there an ip
address I can enter that will be interpreted as "no default gateway?"
is 0.0.0.0 a valid input? If so, what does it mean? Thanks in
advance for any insight on this one.
