Summary
IP pools are used to define range of IP addresses that can be used by various RouterOS utilities, for example, DHCP server, Point-to-Point servers and more. Separate lists for IPv4 and IPv6 are available. Whenever possible, the same IP address is given out to each client (OWNER/INFO pair).
IPv4 Pool
Sub-menu: /ip pool
| Property | Description |
|---|---|
| comment (string; Default: ) | Short description of the pool |
name (string; Default: ) | Unique identifier of the pool |
| next-pool (string; Default: ) | When IP address acquisition is performed a pool that has no free addresses, and the next-pool property is set, then IP address will be acquired from next-pool |
| ranges (IP; Default: ) | IP address list of non-overlapping IP address ranges in the form of: from1-to1,from2-to2,...,fromN-toN. For example, 10.0.0.1-10.0.0.27,10.0.0.32-10.0.0.47 |
Example
To define a pool named "my-pool" with the 10.0.0.1-10.0.0.126 address range excluding gateway's address 10.0.0.1 and server's address 10.0.0.100, and the other pool dhcp-pool, with the 10.0.0.200-10.0.0.250 address range:
[admin@MikroTik] ip pool> add name=my-pool ranges=10.0.0.2-10.0.0.99,10.0.0.101-10.0.0.126
[admin@MikroTik] ip pool> add name=dhcp-pool ranges=10.0.0.200-10.0.0.250
[admin@MikroTik] ip pool> print
# NAME RANGES
0 ip-pool 10.0.0.2-10.0.0.99
10.0.0.101-10.0.0.126
1 dhcp-pool 10.0.0.200-10.0.0.250
Used addresses
Sub-menu: /ip pool used
Here you can see all used IP addresses from IP pools.
Read-only properties
| Property | Description |
|---|---|
| address (IP) | IP address that is assigned to client from the pool |
info (string) | For DHCP MAC address from leases menu and for PPP connections username of PPP type client |
| owner (string) | Service which is using this IP address |
| pool (string) | Name of the IP pool |
IPv6 Pool
Sub-menu: /ipv6 pool
| Property | Description |
|---|---|
| name (string; Default: ) | Descriptive name of the pool. |
| prefix (IPv6/0..128; Default: ) | Ipv6 address prefix |
| prefix-length (integer [1..128]; Default: ) | The option represents the prefix size that will be given out to the client. |
Read-only properties
| Property | Description |
|---|---|
| dynamic (yes | no) | Whether the pool is dynamic. |
| expire-time (time) | Expire time is set to dynamic pools added by DHCPv6 client. |
Example
The example will create a pool of "2001::/60" to give out /62 prefixes:
[admin@test-host] /ipv6 pool> add name: test prefix: 2001::/60 prefix-length: 62 [admin@test-host] /ipv6 pool> print # NAME PREFIX PREFIX-LENGTH 0 test 2001::/60 62bits
Used addresses
Sub-menu: /ipv6 pool used
Read-only properties
| Property | Description |
|---|---|
| info (string) | Shows DUID related information received from the client (value in hex). Can contain also a raw timestamp in hex. |
| owner (string) | What reserved the prefix ("DHCP", etc.) |
| pool (string) | Name of the pool. |
| prefix (IPv6/0..128) | IPv6 prefix that is assigned to the client from the pool. |
