OK my dumb teacher threw a major curve ball at me today:

The local LAN has been assigned an IP network Address of 192.168.0.0/20(router1)
192.168.160.0/20(router2)

Each subnet of the above network needs to accomdate 300 host addresses.
User the 3rd usable subnet for the LAN. Do not use subnet zero as the first subnet.

I figured that the address using VLSM is 192.168.23.254 /23 but when i try to enter that into Packet Tracers router interface an error pops up sying this cant be done with that subnet mask. Anybody get a different answer.

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?

Impressed you have kept this alive this long EP! So many sites have come and gone. :(

Just did some crude math and I apparently joined almost 18yrs ago, how is that possible???
