Subnetting Question?


OSNN Senior Addict

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

The local LAN has been assigned an IP network Address of

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 /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.

Hey EP! All good with me, applying for Microsoft MVP right now, should have done this a while ago.

Notifications don't work, I only found your response by coming back to hunt up some threads, if you want, give me your email address so we can keep in touch easier!

EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there!
