Dynamic Host Configuration Protocol (DHCP)






There are conflicts between the bindings of the DHCP server and the IP address ranges of the scopes present on the server


The DHCP server might lease its own static IP address to a client computer, leading to an IP address conflict and disruption of DHCP service.


Use the DHCP MMC to exclude the DHCP server IPv6 addresses from the scope.

To exclude IP address from a scope

  1. Click Start, point to Administrative Tools and then click DHCP.

  2. In the console tree, expand the applicable DHCP server, expand IPv6, and then expand the applicable scope

  3. Right-click Address Pool, click New Exclusion Rangeā€¦, type the IPv6 addresses to bind, and then click Add.
