I'm not sure, but this is the only place I can think of where this
question might fit.

I have a network 6.5 environtment. What I'm doing in our organization is
I'm turning off any switch ports that are not currently use. But
sometimes, I forget to do this.

Now, is there a way that I can limit the IP configuration on the
workstations that are not authenticated in eDirectory?

Say like someone brought in a laptop and plugged it on my network. I want
them to be able to get an IP address and Subnetmask, but not the Gateway
information and only allow them to get the Gateway information only when
they authenticate through eDirectory.

Please let me know.
