SYMPTOMS

Consider the following scenario:
  • Lots of IP addresses are assigned to one network adapter on a computer that is running Windows Server 2008 Service Pack 2 (SP2) or Windows Vista Service Pack 2 (SP2).
  • Only the primary IP address is used for outgoing traffic.
In this scenario, only the primary IP address should be registered on the DNS servers for outgoing communication purpose. However, all IP addresses are registered on the DNS servers.

The issue causes the following symptoms:
  • The communication to the computer is blocked by a firewall. Because all IP addresses are registered on the DNS servers, all these IP addresses seem to be valid IP addresses that can be used to communicate with the computer. However, if only the primary IP address can pass through a firewall, communication that uses all other IP addresses is block by the firewall.
  • A large amount of DNS registration traffic and a large amount of update traffic is generated. However, this traffic is unnecessary because these IP addresses are not used for outgoing traffic.

CAUSE

This problem occurs because all assigned IP addresses are registered on the DNS servers. This is by default. Additionally, there is no option made available to change this default behavior.

RESOLUTION

After you install this hotfix, you can create IP version 4 (IPv4) addresses or IP version 6 (IPv6) addresses by using the netsh command together with the new "skipassource" flag. By using this flag, the added new addresses are not used for outgoing packets unless explicitly set for use by outgoing packets. Therefore, these IP addresses will not be registered on the DNS servers.

For example, the following is a netsh command together with the new "skipassource" flag for an IPv4 address:
Netsh int ipv4 add address <Interface Name> <ip address> <subnet mask> skipassource=true
