## Detailed Description

a common structure for IPv4 and IPv6 leases

This structure holds all information that is common between IPv4 and IPv6 leases.

Definition at line 31 of file lease.h.

## Member Enumeration Documentation

## ◆ Type

enum isc::dhcp::Lease::Type

Type of lease or pool.

Enumerator
TYPE_NA | the lease contains non-temporary IPv6 address
TYPE_TA | the lease contains temporary IPv6 address
TYPE_PD | the lease contains IPv6 prefix (for prefix delegation)
TYPE_V4 | IPv4 lease.

Definition at line 46 of file lease.h.

## Constructor & Destructor Documentation

## ◆ Lease()

isc::dhcp::Lease::Lease | ( | const isc::asiolink::IOAddress & | addr,
|  | uint32_t | valid_lft,
|  | SubnetID | subnet_id,
|  | time_t | cltt,
|  | const bool | fqdn_fwd,
|  | const bool | fqdn_rev,
|  | const std::string & | hostname,
|  | const HWAddrPtr & | hwaddr )

Constructor.

Parameters

  addr | IP address
  valid_lft | Lifetime of the lease
  subnet_id | Subnet identification
  cltt | Client last transmission time
  fqdn_fwd | If true, forward DNS update is performed for a lease.
  fqdn_rev | If true, reverse DNS update is performed for a lease.
  hostname | FQDN of the client which gets the lease.
  hwaddr | Hardware/MAC address

Note
  When creating a new Lease object, current_cltt_ matches cltt_ and current_valid_lft_ matches valid_lft_. Any update operation that changes cltt_ or valid_lft_ in the database must also update the current_cltt_ and current_valid_lft_ after the database response so that additional operations can be performed on the same object. Failing to do so will result in the new actions to be rejected by the database.

Note that This method only sets fields in the structure. It is caller's responsibility to clean up DDNS, bump up stats, log, call hooks ets.

Parameters

  probation_period | lease lifetime will be set to this value
