Abstract

The DHCPv4 [RFC2131] and DHCPv6 [RFC3315] protocol specifications describe how addresses can be allocated to clients based on network topology information provided by the DHCP relay infrastructure. Address allocation decisions are integral to the allocation of addresses and prefixes in DHCP.

     Customizing DHCP Configuration on the Basis of Network Topology

Abstract

   DHCP servers have evolved over the years to provide significant    functionality beyond that described in the DHCP base specifications.    One aspect of this functionality is support for context-specific    configuration information.  This memo describes some such features    and explains their operation.
