The DHCP server role in Windows Server 2012 provides for redundancy with split scope, failover through hot standby and load sharing, and failover clustering.
Failover clustering enables both servers to assign DHCP information by sharing the same DHCP database on a shared storage location.
DHCP filtering configures how the server to responds to clients by using link-layer MAC addresses.
The DHCP Management Pack, part of System Center Operations Manager, enables monitoring and reporting of the DHCP service.
The DNS service supports configurations to enhance security including DNSSEC, DNS socket pool, and cache locking.
You can manage and audit IP addresses in IPAM. You also can provision IPAM with IP addresses that are managed by other DHCP servers.
