Member Data Documentation

◆ changed_leases_

Lease6Collection isc::dhcp::AllocEngine::ClientContext6::IAContext::changed_leases_

A pointer to any leases that have changed FQDN information.

This list may contain old versions of the leases that are still valid. In particular, it will contain a lease if the client's FQDN has changed.

Definition at line 323 of file alloc_engine.h.

◆ hints_

HintContainer isc::dhcp::AllocEngine::ClientContext6::IAContext::hints_

Client's hints.

There will typically be just one address, but the protocol allows more than one address or prefix for each IA container.

◆ ia_rsp_

Option6IAPtr isc::dhcp::AllocEngine::ClientContext6::IAContext::ia_rsp_

A pointer to the IA_NA/IA_PD option to be sent in response.

◆ iaid_

uint32_t isc::dhcp::AllocEngine::ClientContext6::IAContext::iaid_

The IAID field from IA_NA or IA_PD that is being processed.

Definition at line 297 of file alloc_engine.h.

◆ new_resources_

ResourceContainer isc::dhcp::AllocEngine::ClientContext6::IAContext::new_resources_

Holds addresses and prefixes allocated for this IA.

This collection is used to update at most once new leases.

Definition at line 331 of file alloc_engine.h.

◆ old_leases_

Lease6Collection isc::dhcp::AllocEngine::ClientContext6::IAContext::old_leases_

A pointer to any old leases that the client had before update but are no longer valid after the update/allocation.

This collection is typically empty, except cases when we are doing address reassignment, e.g. because there is a host reservation that gives this address to someone else, so we had to return the address, and give a new one to this client.

Lease6Collection isc::dhcp::AllocEngine::ClientContext6::IAContext::reused_leases_

Set of leases marked for reuse by lease caching.

◆ type_

Lease::Type isc::dhcp::AllocEngine::ClientContext6::IAContext::type_
