 * Routers only store network aggregation addresses in their routing tables, thus reducing the average space of a routing table to 8192 entries. This addresses the scalability issues associated with IPv4, which required every allocated block of IPv4 addresses to be exchanged between Internet routers, causing their routing tables to become too large to allow efficient routing.

 These addresses are syntactically indistinguishable from unicast addresses but they address a group of interfaces.
 The packet destined for an anycast address will arrive at the nearest router interface.
-Anycast addresses are only used by routers.

 These addresses identify a group of interfaces.

 If the network has a DHCP server, it is very easy to configure the network interface to use DHCP.
