<table><thead><tr><th width="203">Keyword</th><th>Description</th></tr></thead><tbody><tr><td><code>no</code></td><td>(Optional) This is the same as <code>ip dhcp6-server off.</code></td></tr><tr><td><code>off</code></td><td>Disables the DHCPv6 serveron the interface.</td></tr><tr><td><code>on</code></td><td>Enables the DHCPv6 serve on the interface.</td></tr></tbody></table>

## Defaults

The DHCPv6 server is enabled on LAN interfaces and disabled on WAN interfaces by default.

## Usage Guidelines

This command enables the DHCPv6 server on the interface. Island does not assign IPv6 addresses via DHCP; instead, hosts will use [Stateless Address Autoconfiguration](https://wikipedia.org/wiki/IPv6_address#Stateless_address_autoconfiguration_\(SLAAC\)) (SLAAC) to obtain their IPv6 address. Island's DHCPv6 server provides DNS and other requested information to IPv6 clients.

This command is valid only in interface context. Entering it will set the [interface mode](/island-router-cli-2.3.2/commands/ip-interface-context/ip-autoconfig.md) to `manual`.

## Examples

```
ip dhcp6-server on
```
