Re: Running out of LAN IP addresses
If it is a gigabit LAN the degredation probably isn't even perceived
"humanly" if the actual hosts are only a small amout higher than 300, but
I'm sure it could be measured with equipment. If anything, the number of
broadcast created by that number of hosts has got to mean something, and the
LAN would have to perform be better if they were reduced. Anyway I like to
stay within recommendations and standards rather than doing something just
because I can get away with it,..especially when I am making recommendations
to others.
I wish I had a link or a reference but I don't. It was something mentioned
"along the way" within the Cisco Textbook material they use for the CCNA
exams in the Colleges that have those courses. I am on the IT Advisory
Committee for the local college in my area and so I have contact with those
instructors. I recently asked one if the 250-300 host recommended limit was
still the case to make sure I wasn't day dreaming or something back when I
went through the classes. He said that it was true but he didn't have any
exact refernces or quotes to give me. But if I ever find any, I'll be sure
to keep track of them. I still have those textbooks, but it seems to be a
needle in the hay stack to find the quote.
