This document defines a protocol, Multicast Address Dynamic Client Allocation Protocol (MADCAP), that allows hosts to request multicast addresses from multicast address allocation servers.
Multicast Address Dynamic Client Allocation Protocol (MADCAP) is a protocol that allows hosts to request multicast address allocation services from multicast address allocation servers. This protocol is part of the Multicast Address Allocation Architecture being defined by the IETF Multicast Address Allocation Working Group. However, it may be used separately from the rest of that architecture as appropriate.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 .

RFC 2730 MADCAP December 1999
This specification uses a number of terms that may not be familiar to the reader. This section defines some of these and refers to other documents for definitions of others.
MADCAP client or client A host requesting multicast address allocation services via MADCAP.
MADCAP server or server A host providing multicast address allocation services via MADCAP.
Multicast IP Multicast, as defined in  and modified in .
Multicast Address An IP multicast address or group address, as defined in  and . An identifier for a group of nodes.
Multicast Scope A range of multicast addresses configured so that traffic sent to these addresses is limited to some subset of the internetwork. See  and .
Scope ID The lowest numbered address in a multicast scope. This definition applies only within this document.
Scope Zone One multicast scope may have several instances, which are known as Scope Zones or zones, for short.
For instance, an organization may have multiple sites. Each site might have its own site-local Scope Zone, each of which would be an instance of the site-local Scope. However, a given interface on a given host would only ever be in at most one instance of a given scope. Messages sent by a host in a site-local Scope Zones to an address in the site-local Scope would be limite...
