lease4-del command handler
This command attempts to delete an IPv4 lease that match selected criteria. It extracts the command name and arguments from the given Callouthandle, attempts to process them, and then set's the handle's "response" argument accordingly.
Two types of parameters are supported: (subnet-id, address) or (subnet-id, identifier-type, identifier).
Example command for deletion by (subnet-id, address): { "command": "lease4-del", "arguments": { "subnet-id": 1, "ip-address": "192.0.2.202" } }
Example command for deletion by (subnet-id, identifier-type, identifier) { "command": "lease4-del", "arguments": { "subnet-id": 1, "identifier-type": "hw-address", "identifier": "00:01:02:03:04:05" } }";

| int isc::lease_cmds::LeaseCmds::lease4UpdateHandler | ( | hooks::CalloutHandle & | handle | ) |
lease4-update handler
This command attempts to update existing IPv4 lease. The parameters specified will replace existing lease. The only condition is that the IP address must not change. If you want to change the IP address, please use lease4-del and lease4-add instead. It extracts the command name and arguments from the given Callouthandle, attempts to process them, and then set's the handle's "response" argument accordingly.
Example command: { "command": "lease4-update", "arguments": { "subnet-id": 44, "ip-address": "192.0.2.1", "hw-address": "1a:1b:1c:1d:1e:1f", "hostname": "newhostname.example.org" } };
The optional 'force-create' boolean parameter may be specified to force the lease to be created if it doesn't exist. By default, this parameter is set to false, which means that the lease is not created.

lease4-wipe handler
This commands attempts to remove all IPv4 leases from a specific subnet. Currently the leases are removed from the database, without any processing (like calling hooks or doing DDNS cleanups). It extracts the command name and arguments from the given Callouthandle, attempts to process them, and then set's the handle's "response" argument accordingly.
Example command: { "command": "lease4-wipe", "arguments": { "subnet-id": 44 } }";

lease6-del command handler
This command attempts to delete a lease that match selected criteria. It extracts the command name and arguments from the given Callouthandle, attempts to process them, and then set's the handle's "response" argument accordingly.
Two types of parameters are supported: (subnet-id, address) or (subnet-id, type, iaid, identifier-type, identifier).
Example command for deletion by (subnet-id, address): { "command": "lease6-del", "arguments": { "subnet-id": 1, "ip-address": "192.0.2.202" } }
Example command for deletion by (subnet-id, type, iaid, identifier-type, identifier): { "command": "lease6-del", "arguments": { "subnet-id": 1, "type": "IA_NA", "iaid": 123456, "identifier-type": "hw-address", "identifier": "00:01:02:03:04:05" } }";

lease6-update handler
This command attempts to update existing IPv6 lease. The parameters specified will replace existing lease. The only condition is that the IP address must not change. If you want to change the IP address, please use lease6-del and lease6-add instead. It extracts the command name and arguments from the given Callouthandle, attempts to process them, and then set's the handle's "response" argument accordingly.
Example command: { "command": "lease6-update", "arguments": { "subnet-id": 66, "ip-address": "2001:db8::1", "iaid": 7654321, "duid": "88:88:88:88:88:88:88:88", "hostname": "newhostname.example.org" } }";
The optional 'force-create' boolean parameter may be specified to force the lease to be created if it doesn't exist. By default, this parameter is set to false, which means that the lease is not created.

This command attempts to add a lease. It extracts the command name and arguments from the given Callouthandle, attempts to process them, and then set's the handle's "response" argument accordingly.
This function covers both v4 and v6 leases.
Example command for v4: { "command": "lease4-add", "parameters": { "address": "192.0.2.1", "hwaddr": "00:01:02:03:04:05", "client-id": "this-is-a-client", "valid-lft": 3600, "expire": 12345678, "subnet-id": 1, "fqdn-fwd": true, "fqdn-rev": true, "hostname": "myhost.example.org", "state": 0 } } Example command for v6: { "command": "lease6-add", "arguments": { "subnet-id": 66, "ip-address": "2001:db8:abcd::", "type": "IA_PD", "prefix-len": 48, "duid": "01:02:03:04:05:06:07:08", "iaid": 1234, "preferred-lft": 500, "valid-lft": 1000, "expire": 12345678, "fqdn-fwd": true, "fqdn-rev": true, "hostname": "urania.example.org"" } }
