# lease > Leases of the DHCP servers. Dynamic leases are created when clients get an address from a pool; static leases give a specific client a fixed address, a pool, or its own settings. For details, see DHCP Server. ----------- ## ip/dhcp-server/lease **Type:** Directory Leases of the DHCP servers. Dynamic leases are created when clients get an address from a pool; static leases give a specific client a fixed address, a pool, or its own settings. For details, see [DHCP Server](../../../../network-management/dhcp/server). The lease is disabled. The lease was assigned by a RADIUS server. The lease is dynamic: it was created when a client got an address from the pool. Use `make-static` to turn it into a static lease. The client is blocked (`block-access=yes`) and gets no reply from the server. IP address of a static lease, or the name of an IP pool to give the client an address from. With `0.0.0.0`, the address pool of the server is used. MAC address of the client the static lease is for. Whether to identify the client by the source MAC address of its packets instead of the client hardware address field (`chaddr`) of the DHCP message. Client identifier (option 61) of the client the static lease is for, in the format shown in `active-client-id`, for example `1:4e:97:a1:4c:d1:38`. Bandwidth limit for the client, as `rx-rate[/tx-rate] [rx-burst-rate[/tx-burst-rate] [rx-burst-threshold[/tx-burst-threshold] [rx-burst-time[/tx-burst-time]]]]`. Rates are in bits per second, with an optional `k` or `M` suffix, and missing tx values are taken from the rx values. Only static leases can have a rate limit. The server creates a dynamic simple queue named `dhcp-ds` for the address of the lease, with this limit as `limit-at` and `max-limit`. Routes the server adds while the lease is bound, as `dst-address/mask gateway distance` entries separated by commas, for example `10.77.0.0/24 172.31.255.105 5`. Where to place the dynamic simple queue created for this lease: `first` (default) at the top of `/queue/simple`, `bottom` at the end, or before the named queue. Parent of the dynamic simple queue created for this lease. Default: none. Queue type of the dynamic simple queue created for this lease. Firewall address lists to which the address of the lease is added while the lease is bound. DHCP server the lease belongs to. With `all`, the static lease is valid on every server. Whether to block the client: the server does not answer it, and the lease gets the `B` flag. Default: no. Whether this lease and a DHCPv6 binding of the same client share one dynamic simple queue, which then contains both the IPv4 and the IPv6 address. Default: yes. Lease time for this client. When not set, or set to `0s`, the `lease-time` of the server is used. Whether to broadcast replies to this client even when it has not set the broadcast flag. Default: no. Options (`/ip/dhcp-server/option`) to send to this client. They take precedence over the options of the server and of the network. Option set (`/ip/dhcp-server/option/sets`) to send to this client. It takes precedence over the options of the server and of the network. When set, the lease matches requests whose relay agent information (option 82) contains this circuit ID, even if the MAC address or client ID differ. When set, the lease matches requests whose relay agent information (option 82) contains this remote ID, even if the MAC address or client ID differ. State of the lease: - `waiting` - A static lease that is not in use. - `testing` - The server is checking the address for conflicts (`conflict-detection`). - `offered` - The server offered the address and waits for the client's request. - `bound` - The client uses the address. - `authorizing` - The server waits for the reply from the RADIUS server. - `conflict` - Another host already uses the address. The lease keeps the address out of use for the lease time; `check-status` frees it when the other host no longer answers. - `declined` - The client declined the address with a DHCPDECLINE message. Time until the lease expires. Time since the server last received a request from the client, or `never`. Time since the lease was created. IP address the client uses. MAC address of the client that uses the lease. Client identifier (option 61) of the client that uses the lease. DHCP server that serves the client. Circuit ID from the relay agent information (option 82) of the client's request, in hex. Remote ID from the relay agent information (option 82) of the client's request, in hex. Circuit ID from the relay agent information (option 82) of the client's request, as text. Remote ID from the relay agent information (option 82) of the client's request, as text. Host name the client sent (option 12). DHCP option 60 from last received DHCP request Source MAC address of the client's last request. Key the server gave the client, in its reply when the client bound, for authenticating Reconfigure messages (RFC 6704, HMAC-MD5). Requires `use-reconfigure` on the server. Replay-detection counter of the last Reconfigure message sent to the client. It increases with every Reconfigure message.
