To prevent this behaviour you need to install below mentioned hotfix and add the addresses using the following netsh syntax: Netsh int ipv4 add address skipassource=true http://support.microsoft.com/kb/975808/EN-US http://jbits.se/blog/2011/02/24/prevent-w2k8-from-registering-all-adapter-ips-in-dns/ By default, IIS will bind a certain port to all IPs sharing NIC.
