How long can the Internet last if every customer needs to get a /24? That is what appears to be with Windows/NT 4.0. This server has lately become very popular with small customers that install an NT server and a few PCs and want a connection. ISPs up to know would assign a /26 or perhaps a /27 or even a /30 to SOHOs like this. Windows NT 4.0 when defining the address range as well as the DNS and inverse - only has space in the form for 3 octets. They assume you are a /24 or larger. I have had customers come back to me and say that they can't even enter the 255.255.255.224 mask I gave them on their system since the NT doesn't support it. Let alone the problems with inverse subnetting that there is a draft RFC out there that almost everyone follows. Seems to have slipped by the people in Oregon, though. I have been very careful up till now to make optimal use of IP address space but I fear with the plenthora of WinNT 4.0s out there we will see 2% utilization of IP address space in the future. Am I missing something here on WinNT installs? Or is Microsoft gonna cause the IP address space to expire sooner than we had planned? Hank Nussbacher IBM Israel - - - - - - - - - - - - - - - - -
