IT HAPPENS TO BE the maximum number of IP addresses that can be assigned to any combination of NICs under Microsoft?s Windows 2000. BugNet tests have verified that once the magical 52nd IP address is reached, without any warning or fanfare, Windows 2000 Server?s Active Directory misplaces all of its directory objects.
So who cares?
On the surface this may seem like an obscure limitation of Windows 2000. Why would anyone ever want or need to assign 51 IP addresses? For most Windows 2000 server installations, this will never be an issue. However, there are organizations that are doing their own Internet hosting (i.e. Web, e-mail, FTP services, etc.). This constraint limits the flexibility in providing Internet/intranet services for their organizations on the Windows 2000 Server platform.
ISPs and Web hosters are the most likely to configure that many IP addresses on a server. This procedure allows them to host multiple Web sites on the same computer. Using multiple IP addresses isn?t the only way to create multiple Web hosts on the same box, but it does allow the greatest flexibility for the hosting customers. It is also conceivable for a company, wanting to consolidate services, to run 50+ subnets on a single NIC.
Vage bug hoor...
