dnsmasq ipv6 dhcp

dnsmasq是一个常用的DNS和DHCP服务器软件，它可以支持IPv4和IPv6地址的分配。如果你想使用dnsmasq提供IPv6 DHCP服务，你需要在dnsmasq的配置文件中添加以下内容：

dhcp-range=::100,::1ff,constructor:eth0,ra-names,slaac

这个配置会为连接到eth0接口的设备提供IPv6地址，地址范围是从::100到::1ff。其中，ra-names表示使用路由器通告来分配IPv6地址，slaac表示使用SLAAC方式分配IPv6地址。你可以根据实际需要修改这些参数。

在添加完这个配置后，你需要重新启动dnsmasq服务以使配置生效。然后，你的设备就可以从dnsmasq服务器上获取IPv6地址了。

dnsmasq dhcp ipv6

Dnsmasq is a lightweight DNS and DHCP server software that can be used to provide IPv6 addresses to clients via DHCPv6. Here are the basic steps to configure Dnsmasq to provide IPv6 addresses to clients:

1. Install Dnsmasq on your server.
2. Edit the Dnsmasq configuration file (/etc/dnsmasq.conf) and add the following lines to enable DHCPv6:

dhcp-range=::100,::1ff,constructor:eth0,ra-names,slaac
enable-ra

The first line sets the range of IPv6 addresses to be assigned to clients. The "constructor:eth0" option specifies that the IPv6 addresses should be assigned to clients on the eth0 interface. The "ra-names" option tells Dnsmasq to include the clients' hostnames in the Router Advertisement messages. The "slaac" option enables Stateless Address Autoconfiguration, which allows clients to generate their own IPv6 addresses based on the prefix advertised by the router. The second line enables Router Advertisement messages, which tell clients about the network's IPv6 prefix and other configuration information.

3. Restart the Dnsmasq service to apply the changes:

sudo systemctl restart dnsmasq

4. Configure your router to advertise the IPv6 prefix assigned to your network by Dnsmasq. This will allow clients to automatically configure their IPv6 addresses.

With these steps, you should have a working DHCPv6 server on your network, providing IPv6 addresses to clients.

dnsmasq dhcp ipv6 ipv4

Dnsmasq is a lightweight DNS and DHCP server that can be used to provide both IPv4 and IPv6 addresses to clients on a network. It is commonly used in small networks, such as home networks, to provide local DNS resolution and DHCP services.

To configure Dnsmasq to provide both IPv4 and IPv6 addresses, you will need to edit the configuration file (/etc/dnsmasq.conf by default) and add the following lines:

dhcp-range=192.168.1.50,192.168.1.150,12h
dhcp-range=::100,::200,constructor:eth0,ra-names,slaac,12h

The first line specifies a range of IPv4 addresses to be assigned to clients, while the second line specifies a range of IPv6 addresses to be assigned to clients. The "constructor:eth0" option specifies that the IPv6 addresses should be assigned based on the interface (eth0) that the client is connected to, while the "ra-names" and "slaac" options specify that the addresses should be assigned using Router Advertisement (RA) messages and Stateless Address Autoconfiguration (SLAAC).

You may also need to enable IPv6 support in Dnsmasq by adding the following line to the configuration file:

listen-address=::1,127.0.0.1

This specifies that Dnsmasq should listen on the IPv6 loopback address (::1) as well as the IPv4 loopback address (127.0.0.1).

Once you have made these changes, you can start or restart the Dnsmasq service to apply the new configuration.
